Hi all, I've got a B-Band UST (forgot the model, it's got a battery, but no other controls, just a preamp as a part of the endpin itself) installed in my Guild acoustic and I've never had any problems with this setup. But at this 1 particular gig that i do sometimes, it picks up a terrible hum. I tried all kinds of combinations ( different cables, with and without the DI, different DI ) and the hum is always there at this spot. I also tried a different DI with a ground lift, and although there was a very slight improvement, the hum was still there, and prominent. However, the hum will go away when I : 1) move about 2-3 feet off the stage 2) touch my DI box (LR Baggs ParaDI) and the strings at the same time. For the record, the other guitar player was using a mid-end Ibanez acoustic with onboard preamp/electronics and it was totally hum-free. Any suggestions on how I can overcome this problem? I'm thinking the B-band wasn't installed properly or the B-Band is too sensitive to this particular venue's electrical system/Radio waves/lights? Any help or suggestions would be great! Thanks in advance!
