FLAMMA FX20 Guitar Headphone Amp with APP 40 Drum Grooves 52 Amp Modes 5 Delay 5 Reverb Effects 14 Modulations for Practice Recording and Creativity

I am enjoying this little headphone amp. It is small, light, easy to use, and is loaded with features. -There are a few things I would add or change, but overall it is a great product. It fits. The 270º rotation of the 1/4" (6mm) plug along with the offset when opened 180º allows it to work with most guitars. (I say most because there are some wild guitar builds out there and some might not have conventional output jacks.) I tried it with two guitars I built, a Squire Strat, and a Hoffner guitar. It fit all. As for fit, if your jack isn't tight, the amp will spin (see video). This was only an issue with the Hoffner. I will bend the contacts in slightly so the plug fits securely. Features. With a billion combinations you can't go wrong. 14 different amp models with individual save function 14 built-in effects with parameter adjustment 5 levels of TONE color 28 different drum groove options to select from Compatible with Bluetooth for audio playback Supports USB AUDIO recording and audio playback Pick your Amp, pick your EFX, pick your Tone, and pick your Groove. The selections are identified by colors that corollate to the options. See chart in last two images. Once you pick your groove you can modify it with the +/- buttons. The options are to change the speed and the beat volume (in relation to your guitar). The EFX has "hidden parameters" - hold the EFX button when EFX is selected and use the +/- buttons to adjust between ten different levels. With the Bluetooth feature you can connect your device and play along with your favorite songs or backing tracks. The amp also lets you record on a laptop, phone, or tablet through the USB C port. So yes, it can shape your sound and offers a lot of tonal colors. I listened to this amp through some cheap over the ear headphones, a pair of Sennheiser headphones, and a pair of Bose noise cancelling headphones. It sounded great through all of them. -although my playing is questionable... ha. Like I said at the beginning there are a few things that I would add or change with this power packed tiny amp. I'm not docking any stars because it works great as it is. But Flamma, if you're listening, here are a few things that might make "FX10.v2" even better: Memorizing is hard. I would add a small screen on the front with a readout for which Amp, EFX, Tone, and Groove is selected. It would be nice to add the time signature of the groove and the tempo. A three or four bar "battery Level" indicator would be nice too. You wouldn't rely on a sheet with colored dots and amp names, or guess the exact tempo, or when to recharge. The text under the selection buttons is small. It is hard to read when you have the guitar on and are looking down at the amp. The screen on the front would help with that. -a button to backlight the screen (for playing in those dark windowless rehearsal spaces) would help too. Three buttons to save and retrieve to create your own three presets. Push one to change the sound mid-song to your preset, with out having to cycle through all the colors. If there was a Bluetooth send feature so you could pair with wireless headphones or a Bluetooth speaker it would be nice. Again, this thing works great as is. These are just ideas that might make "FX10.v2" even better. (Or we can collaborate and make an FX10 - Sprocket 67 Edition.) Yes, it is a product I'd put my name on... and I'm pretty picky.

I have owned a few products like this before, but it appears they have come a long way since the last time I tried one. As someone who owns a lot of amps and effects, this is something I would mostly use while traveling or if I wanted to practice quietly. For those purposes, there is a lot to like here. The amp simulations sound quite good, and while the effects lean heavily on reverb in most iterations, there are a lot of varieties to choose from, and Flamma does reverbs quite well. The drums sound good, even if there are a limited number of choices, but it is still more enjoyable to play to than a metronome. Making adjustments to tempo and effects require a number of extra button presses involving holding buttons and double-tapping, but I was glad when I was able to figure them out, because it makes it a lot more useful. Adjustments to the amp models and effects were a bit challenging for me, because they rely upon an extensive set of color-coded LEDs, and I am color blind, so that was challenging. I was generally able to realize that the further up the amp models you went, the more gain, and as you increase the FX, you get into bigger reverbs, then delays, and combinations at the end. I would be hard pressed to know which amp I was using because of the color code, but I still found it quite usable. As intended, the plug does a great job for the guitar. It also does a great job enhancing synthesizers that don't have effects. I tried it with the Arturia Microfreak, and it adds some much needed grit and ambience to patches in a small form factor. The Bluetooth features work as designed, and though they are designed to stream music and backing tracks, they also do well with iOS synthesizers. When I purchased this, I wasn't sure what an OTG cable was, but it turned out I already had several. I had some issues getting the device to work on my iPad with Cubasis, but as it turns out, it works quite well out of the box on my laptop in Studio One as a guitar-focused USB audio interface that was instantly recognized and required no setup for me. Recordings were very low noise and sounded great. There are fewer controls or options compared to my plugins, but it is much faster to dial in a sound for quick demos, and cleaner settings do a great job of delivering a direct signal to use with plugins if so desired. I had hoped mostly to get a practice tool, but ended up with that along with a convenient audio interface and mixer, as well.

It's an excellent product and it performs just as advertised. With a couple of cables and adapters, you can actually plug it in to an amp and use all of its functions including the drum machine.

The Flamma FX10 is basically a fully featured practice amp shrunk to the size of a mint tin. It plugs straight in to your guitar and outputs directly to headphones, using very minimal cables and making it an ideal solution for practicing on the go. I've been very impressed with the amp models, while there aren't a huge number to choose from, the included models are diverse and effective. There are patches with crisp cleans, blues-style break up, as well as some more extreme, scooped 80's metal kind of sounds. The included effects are impressive too, particularly the massive sounding reverb and the sparkly chorus. The interface is simple, you just select whether you want to change Amp or Effect and then you have some buttons for scrolling left and right. There is also an included drum machine, though I haven't experimented much with it. I love that it charges with USB-C and has Bluetooth capability as well. The only con I can really think of is that the amp itself is attached to a 1/4" plug that turns on an axis and it isn't the most secure on certain guitar models. It would have been nice to see that piece have something to lock that mechanism so it wouldn't shift out of position. I also think my dream version of this product would have included a tuner, but that would probably require a display of some sort and it might not be cost-effective or as portable. Overall though, if you're looking for a headphone amp I think it would be hard to do better for under 100$.

I am super impressed with the FX10! I use it with a Fender HSS Strat and am able to get some really high quality tones from the amp models. I love all the models, and some of my favorites are the SOLO 100, Cali V, US Sonic, and the Acoustic Simulator (which reminds me a lot of the Boss pedal). Great dynamic response. Five tone settings. With my Sony headphones, I tend to like the tone set right in the middle. Also, remember the quality of your headphones will affect the sound. If you have thin sounding earbuds, you can compensate by selecting a warmer sound with the tone control. I also used a stereo Roland mini speaker with 3.5” TRS cable and went a little brighter on the tone. The effects are very nice as well. Reverbs are lush and shimmery, depending on the specific one, and you can set the reverb level you like. Nice delays, chorus, phaser, flanger, and tremolo (all include reverb paired with them), or OFF. By holding down the FX button, you can access the FX parameter control, which affects either the reverb level, delay time, or mod depth or rate, depending on the specific effect. It’s a very well-thought out, streamlined interface. You’ll have exactly the control you need over parameters. The drum patterns are a blast! Many genres are available. You can control the drum level relative to the amp, and tempo (40-260bpm). Very nice. The Bluetooth receiver works great with both iOS and Android. On Android, there will be two signals that show up from the FX10. Choose the one for audio (the one with four icons). Sound comes in crystal clear. I look forward to trying it with an OTG cable and recording some of my ideas. Again, I really love this headphone amp. Perfect for quiet practice, travel, or just being in your own world. Be sure to read through the online manual. Don’t worry; it’s quick and easy!

With decades as a guitarist, I've had any number gadgets over the years. I have used the Vox headphone amp for quite a few years, but with the purchase of another new axe, I decided to see if there was something "new". Thus, I came across the Flamma FX20. What appealed to me was: 1) more amp and effects models, 2) an iOS app for max control, 3) Bluetooth input of music tracks for accompaniment, and 4) the addition of drum tracks. I also wanted something that was rechargeable instead of having to always worry about batteries depleting. Overall, I’m pleased with the unit, but do have a couple issues. So far I’m fairly impressed with the amp and effects modeling. My practice amp is a Vox Valvetronix with absolutely exceptional models of various vintage amps and effects. While the Flamma is perhaps not quite as good, for its size and price I can’t really complain. It’s also nice to be able add a drum track for jamming. I can also say that the iOS app is fairly good and connects to the dongle via Bluetooth instead of requiring a hardwire connection like the Vox app for the Valvetronix. I also like that I can play along to music from my iOS device via Bluetooth, thus making all connections to the app and music track wireless. (And, no, the unit does not have support for Bluetooth wireless headsets.) Probably my biggest “complaint” is the setting of the 4 presets for amp/effects available on the dongle when not connected to the app. Listening to a YT video demo of this unit and following the very limited instruction manual (there are none for the app, sadly), it appears that in the app there are 10 overall sets with 4 presets available in each set (40 total presets). Only one of the 10 sets of 4 is available on the dongle if not connected to the app. It appears that whatever set you quit the app in, that set of 4 presets are then available to switch between on the dongle (when not connected to the app). Each of the 4x10 (40) presets in the app can be modified to an extreme with any combination of 52 amps, 14 modulator pedals, 5 delay pedals and 5 reverb pedals. Yes, you can come up with almost any imaginable “sound” — with the odd exception of an overdrive pedal. Of course, you can adjust the various amp settings for overdrive, so not impossible to get the effect/sound, but it would have been nice to have an overdrive effect/pedal. My biggest disappointment is that there is no “spare” bank or banks to store your own custom presets. Thus, while you can go in and set up or modify any of the 40 presets, once they are modified and you want to save the new one, apparently you are required to overwrite an existing preset. Thus a HUGE caution!!!!! If you save a new one, you might want to write down the exact settings from the stock preset before doing the save!!! It also appears that if you want to have 4 custom presets available of the unit when not connected to the app, you need to overwrite all 4 within the same set (sets are identified as 0A, 0B, 0C, 0D, 1A, 1B…etc. up to 9A, 9B, etc.). Thus, you will have to overwrite 4 of the stock presets in order to get your own 4 special presets. Then before quitting the app, be sure you are in that custom set before quitting the app. The dongle will then rotate between that custom set of 4 modified presets when pushing the dongle's Preset Selection button. It is also nice that you can connect the dongle via USB cable to a computer or iOS device to input the sound (including drum track) to that device and into something like GarageBand/Logic, etc. for recording. Pros: • Works with iOS and iPadOS • Modeling of amps and effects is quite good • Compact • Rechargeable (USB) • Bluetooth for app connection • Bluetooth for music input to headphones from iOS • Decent selection of drum tracks • USB output to a device for recording • Posted a question and within 24hrs had a response from Flamma Cons: • Cannot save modified presets without overwriting existing presets. • Cannot switch between sets of 4 presets (there are 10 sets) unless connected to app • Instruction manual is very, very limited and somewhat inadequate • There is no instruction manual for the app leaving a person reliant on YT videos and guessing

I have the FX10 and love it. When I heard the FX20 was out, I watched several videos on it and decided to pull the trigger. The FX20 is more of a down-grade and I was sorely disappointed. First of all, the swivel arm on the unit was loose causing a bad connection with the guitar which resulted in audio cutting in and out. The FX20 only has 4 savable preset slots whereas the FX10 has 14. The FX20 is mostly reliant on the App for Amp simulations and tone adjusting, which isn't awful, but it defeats the purpose if you can only store 4 presets. I reached out to Flamma Customer Service twice to address the loose swivel arm issue and they never responded, indicating they really don't care about faulty or defective equipment. If you have the FX10: keep it and avoid this version. Sometimes, newer is not better.

This is a small and great sounding guitar headphone amp. The sound quality is superb and the different amps are easy to switch between. There are also different effects such as reverb and delay and much more. It's easy to turn the effects on or off. The Flamma FX10 also have a drum machine feature which is very useful when practicing or just jamming as a perfect drumming partner. There are plenty of different drum patterns in different musical styles. The different amps sounds great and I use the clean amps most and they sound fantastic. On each amp you also can change the tone settings from bright to dark in several steps which is very good, it suits all my different guitars pickups. One thing that is rather tricky is to set the different settings for second level of effects, you need to press different buttons and learn what color is what and so on. It works but is a little tricky. I also find it a little tricky to set the tempo for the drum machine. Overall a very pleasant guitar headphone amp I use a lot.
