Does anyone here have experience using a Rolan GK-2B or compatible MIDI pup on a 7 string bass? I would just try it out if I had a GK-2B, but what I have is a bit more permanent. I just reeceived a GK-KIT-BG divided pickup kit and am considering puting it into my Conklin 7 string. If this is doomed to failure, I will just have to grab a cheap 6 string to Frankensteinify. Thanx for any info!
