Chaddy Posted May 10, 2023 Share Posted May 10, 2023 Had abit of fun today... my Sub musicman just went up in smoke in a literal sense. No sound and some head scratching later wondering why and then a gush of smoke out the jack port was a nice surprise. It seems a short happened which burnt the board, abit of the inside went up and the battery was very very hot. I've been debating ripping it out for a while as its one of the too hot China made ones (prefer 12* radius necks). Any recommendations? Open to suggestions but no 100 quid pre-amps!, I feel passive might be safer which is fine. 1 Quote Link to comment Share on other sites More sharing options...
Waddo Soqable Posted May 10, 2023 Share Posted May 10, 2023 You let the magic smoke out....! I would just get a couple of ordinary replacement pots and wire the PU to them as a regular passive thing. Would only cost pennies comparatively. 1 1 Quote Link to comment Share on other sites More sharing options...
fleabag Posted May 10, 2023 Share Posted May 10, 2023 Be careful on which pots you buy if you intend to use your existing knobs. Ask me how i know Quote Link to comment Share on other sites More sharing options...
PaulThePlug Posted May 10, 2023 Share Posted May 10, 2023 Passive... Have a look at the Artec QTP (stellatone-a-thing...) for a Passive Tone Control... bit more 'scope' than a pot 'n 47u... 1 Quote Link to comment Share on other sites More sharing options...
Downunderwonder Posted May 11, 2023 Share Posted May 11, 2023 Idiot question. I always thought pickups were designed with active or passive in mind so is it ok to blithely covert to passive? Quote Link to comment Share on other sites More sharing options...
itu Posted May 11, 2023 Share Posted May 11, 2023 Pickups are designed with some output in mind. If you want a buffer and some tone tweaking with the little help of a battery, it is up to you. True, EMGs need the battery because the buffer circuitry is molded beside the coil(s), but the pickup output can be doped with nearly any preamp. Find your favourite or leave everything out, it is up to your preference. 1 Quote Link to comment Share on other sites More sharing options...

bloke_zero Posted May 11, 2023 Share Posted May 11, 2023 People like these: https://retrovibe.co.uk/product/retrovibe-stinger-77-classic-mm-stingray-bass-eq-pre-amp-2-band-pre-eb-circuit/ I've not tried it myself. A portion of the Stingray sound is the preamp - it adds a bit of bass IIRC. Depends on how keen you are to keep the original tone? I like the MM passive - there is quite a bit of discussion on here about it. Like: Quote Link to comment Share on other sites More sharing options...

Spent ages searching and waiting for a black body maple neck one and now two have appeared online.... sigh. Tone wise the installed pre-amp was terrible and would be too hot for nothing. Pretty sure it was a design fault ( remember reading about it online for a hotfix ). Quote Link to comment Share on other sites More sharing options...

What are you going to do with the extra hole in the control plate :-)? You could try the Passive Treble and Bass circuit they put in G&L basses? I think I have some details if you're interested. The only thing is it's a bass cut and treble cut. Quote Link to comment Share on other sites More sharing options...

Chaddy Posted June 9, 2023 Author Share Posted June 9, 2023 I went l passive with CTS and the old switch craft. My brother has my old multimeter a so I've been head scratching and failing to marry up the pick up wiring correctly by the old trick of headphones and connecting stuff by hand to see the results. There is the following from the standard sub pickup which I think is a dual live and ground for series? Red Black Red & unshielded combined. Anyone got recent experience of subs to confirm this theory? Quote Link to comment Share on other sites More sharing options...
