As I wrote in my review for the VT20+, I use the built in effects a lot on this amp, so I thought I could benefit from this foot switch. It does what it's supposed to do, but could be better. For one, it could do with LEDs to let you know what switches you have on. I my opinion, it's a bit too big. The lead on it is huuuuuuuge. That might be good for on stage use, but in the living room, when the amp is right beside me, it's a nuisance. I actually don't use it half as much as I had hoped I would.
