I've had my Bass V-Amp Pro since 2009, when I bought one from Craigslist. I'd get it all dialed in and then next time, the sound was awful. CR2032 in 5 minutes fixed that.
Well, now I have a more pressing issue. I accidentally broke the effects knob off of the thing while moving it from one rack space to a different rack space. the knobs pull off easily (except the master) and they reveal a plastic shaft underneath. The shaft was broken, not the knob itself. The shaft itself is kind of 'D' shaped so that there's a flat spot on the shaft, and the shaft itself is hollow. This allows adjustment of the effects using a small flat blade screwdriver inserted into the inside of the 'D' but I'd like to get this back in action, as my daughter is wanting to learn to play bass and I'm ready to get her a short-scale from Rondomusic. I probably should just use the editor software and set up a good bank of 5 presets and then be done with it. I'm just wondering if anyone has ever had this issue of breaking one of the selector shafts like I have. I have a call in to the service center in my state, but I may have made the unit somewhat unusable. I will say that I quit using this live at our church, when the church bought a Zoom B3 - which has great presets, and it can connect via USB. There's a B2 unit also, with a volume pedal, which can be found used for $50. So, I'm not married to my Bass V-Amp Pro unit, if someone can help me fix the knob that's great.
