I use it with a bass. It's probably a pedal more suited for guitar because with the bass the variety of sounds is a bit limited. The decay knob is useless because even at minimum the decay is quite long. The tone knob, with a bass, will also stay at minimum because otherwise you lose all the lows. The Q knob will stay at maximum otherwise you don't feel any effect. Then there's the big sensitivity knob, its setting must be adjusted according to the bass's output level, but it's very likely that this knob will always be at full if you want a noticeable effect. In conclusion, for a bass, it's usable but there are definitely better options.

Good filter even on a bass

Really cool!

good sound quality

A very distinctive, successful sound, perfect for funky or silky neo-soul. The quality remains to be seen over time. The design is basic but does the job very well. I chose it for its mini size, it's perfect

Very good product!!! I recommend
