This is the best expression pedal out

This is a perfectly reasonable expression pedal

I was looking for a cheap expression pedal for my Flashback X4 and was unsure if this one would work, but seeing it in the Flashback X4 demo from Pro Guitar Shop, Andy actually uses this one (emailed PGS to confirm as well)

A great expression pedal for a Voodoo Labs Ground Control Pro!

This is a nice little expression pedal, but don't expect the highest quality or durability

This is junk, spend the extra money on a good expression pedal.
