### ⭐⭐⭐⭐⭐ 







  
  
    Omg this is so powerful
  

*by G***1 on Reviewed in the United Kingdom on September 13, 2024*

Neat and petite. Typical Boss construction- would survive a nuclear holocaust, strong and is the size of most other pedals. The sounds are superb. Easy to use but as this is a slow learning curve for me I could do with a tutorial. Great pedal.

### ⭐⭐⭐⭐⭐ 







  
    Costoso ma stupendo.v
  
  

*by S***O on Reviewed in Italy on July 26, 2024*

Bellissimo....un mucchio di incredibili effetti. Io lo uso come tappeto di sottofondo. Simula abbastanza bene la tastiera che posso miscelare con la chitarra. Molti effetti per me sono totalmente inutili.
