ozzy138 Posted July 12, 2023 Share Posted July 12, 2023 A question for the Basschat experts My 2009 4003 Jetglo right out of the blue developed a fault, the bridge pickup sounded thin, i mean real THIN, no sound of it at all when you switch to neck/bridge. Also the vintage push/pull made no real difference. After a trip to a guitar tech Im told the bridge pickup is faulty and needs either rewinding or replacing. A new pick up was fitted (a Retrovibe 12k high gain) and the same issue is pretty much still there, however now i seem to have some bonus problems... The bridge is still way too low and muffled, the treble tone pot may well as not exist the same as the push/pull, there's no noticeable difference in tone... The treble volume, when on full makes everything sound thin again, a few notches back and it seems to get added bass. Turn the bass volume back a few notches and i get another change in sound, its seems to take some bass out..!! Im at a loss, new pots needed? a new cap? or a whole new harness? It appears to be a simple change out of old pickup for new.... bad soldering on my part? Quote Link to comment Share on other sites More sharing options...
Bigguy2017 Posted July 13, 2023 Share Posted July 13, 2023 Could be many things.... The way to approach it is to prep a cable with 1/4" jack (amp) to croc clips. Start with the pickups- unsolder at the pots and connect to the amp with the croc clips - how do they both sound? Next, wire pickup to a volume pot (disconnect tone pots) - does it still sound good - does the volume pot work as expected? Next connect the tone pots (one at a time) - do these work like tone pots? Next, the switch.... croc leads on the 'output' - do all three positions work as expected? If all is good then so far you have two working pickups, two working vol pots, two working tone pots and a working switch OR you will have found some problems to fix... Finally reconnect the output jacks - these are a flippin' nightmare on Rics with the whole Ric-O- Sound stereo / mono switching. It's often easier to fully rewire than try fixing previous dodgy fixes. I'm looking for a good Ric 4003 wiring diagram - best I could find is this... what you really want is a diagram with the parts and wiring shown as-is.
