pedal not working with mixing console

Im using the XLR imput successfully now, but I had to, not use the -20db XLR on the Vtbass, and instead turn the master way down. With the -20db angaged I got crazy clipping, which is kind of odd, because I did not turn the preamp gain up on the mixer to compensate..

anyway
- It works, and XLR is a very nice solution (also because of the phantom power)
thanks for your engagement!
