I've been thinking about getting a volume pedal or a boost pedal to use with my upright. There is a very big volume jump when I switch from pizz to arco. I also think it would be nice to have a little extra something if I need it for solos. Some of the music I've been playing has gotten a little more aggressive and a little extra punch could go a long way. The MXR boost overdrive looks interesting. Does anyone have any experience with that pedal or with any volume pedals?
