Hi, could anyone guide me please with a repair to the above. MM 85A SB Delux series 4 string bass.There is no output to the jack socket, and before I have to shell out £60 for a replacement preamp I would like to be able to test the circuit to find the failed item. I am technically savvy, just never played with guitar innards before, a circuit diagram would be a good start, or any help to check out the components.
thanking you in anticipation
Patrick

By the look I'd say it's the Sterling-5 it's modeled after. That uses a PCB, diagram is here. s93.photobucket.com/user/Rano_01/media/Sterlingschematic.jpg.htmlThe HB will most likely be in a wax potted box which will be nigh on impossible to test. £60 is a fair bit of cash for a preamp,is it the Retrovibe Stinger ?. This one from Artec would do the job perfectly £22.50 delivered. www.thomann.de/gb/artec_se3_basselektronik.htmArtec is no small concern,they build pickups and preamps for all the big names. Good luck. I'll keep an eye out for your progress.
