My Shergold has stereo electronics and it's really annoying me because I have to mess about with mixers and stuff. The problem is that this is causing me to lose power and tone and also means that I can't just plug in and play. I can't bi-amp the bass using a stereo splitter because at the performances I do there is only one amp and I don't have another 450w amp to match it. So any suggestions as to what I can do? There is only a single stereo connection port as well.
