I play elecric gutar, bass and a nylon string with a piezo pickup and this pedal is great for all three!
I combine it with my full pedalbord for the electric and the bass and only use this for the nylon with a bit of reverb. This device is great for really rounding out your sound and basically means you have a boost/amp-feature laden pedal on your chain - it is very useful!
The colour is really cool and the option to have every lider light up is incredibly handy live and at home if playing in the dark.
For the features it has, which is a full 12 band EQ, I find the size of the unit to be perfect as any smaller would have made it quite fiddly, and any larger would have made it cumbersome. The pedal is great for bringing along in a box with your other goodies or in its original case which is sturdy an will last a while being brought around in your backpack.
Do not hesitate - for this price this pedal is very good purchase!
