I recently bought a Bass Max pickup from (All Hail!) Mr Gollihur. Unfortunately I've not been able to try it out properly (loving it so far) since the bass I've been borrowing needed repair and I don't want to mess with the one I have in the meantime. The BM was well worth it's price even before I tried it out though, because of the nice dollar currency here in Sweden : ) My question now is; If I'd like to , in the future, update to say the Bass Master Pro system, could i use my existing Bass Max or do I need to get rid of it and get a whole new system? Probably wouldn't matter financially 'cause I'll probably get a good price for the BM if the dollar doesn't keep dropping, but just out of curiosity... Could I?
