I've recently installed a set of SJB-3 Quarter Pound into my MIM Standard Jazz bass.
I've recorded both the stock and SJB-3 Quarter Pound pickups.
The recording was done straight into my pc, so it's purely the sound of the pickups.
I've recorded them in this order.
Stock: Both full, tone full. (pick)
SJB-3QP: Both full, tone full. (pick)
Stock: Both full, tone off. (pick)
SJB-3QP: Both full, tone off. (pick)
Stock: Neck full, bridge off, tone full. (pick)
SJB-3QP: Neck full, bridge off, tone full. (pick)
Stock: Neck full, bridge off, tone off. (pick)
SJB-3QP: Neck full, bridge off, tone off. (pick)
Stock: Neck off, bridge full, tone full. (pick)
SJB-3QP: Neck off, bridge full, tone full. (pick)
Stock: Neck off, bridge full, tone off. (pick)
SJB-3QP: Neck off, bridge full, tone off. (pick)
Then in the same order again using fingers, then in the same order again but slapping (if you can call it that lol)
This is nothing special, I've only played a few notes, this is only to compare the two pickups that's all.
