I'll keep it brief, sorry but I just can't seem to find the answers here or elsewhere online.... I have a 97 EBMM Sterling 3-band (obviously active). Weak G syndrome. A while back a got the Basslines SMB-4D. Great mellow sound but loud hum. I had the stock pickup re-installed. Recently I revisited this issue; apparently the wrong pickup. I need the SMB-4A (I think) *Can someone confirm that the SMB-4A is compatible with the EBMM stock 3-band preamp? I'm not sure if this is an active or passive pickup. (SD won't return calls or emails) Also opinions if anyone did this upgrade...sorry to bring up a much-discussed topic, but I'm having a hard time finding Sterling info, almost all Stingray... Thanks!
