Adding a Reverend-style “bass contour”

MSedg · July 2023

Evening all,

I’ve a 2010ish SG Classic which needs a new loom (“need” is perhaps too strong, but I refuse to live with the PCB controls - one of the stupider Gibson ideas). I think the pickups are going to stay as I actually like them quite a bit (unusual for me as I usually ditch Gibson pickups).

I’ve been thinking about mods. I’m not really that taken with out of phase tones, but I’ve always been quite interested in the bass roll-off which Reverend offer as standard on their guitars - has anyone done anything similar as a mod? How have the results turned out? Is it feasible in a small-ish SG control cavity?

Cheers!

Don't condemn the PCB out of hand - it's not a problem, both it and the pots are actually very nice quality. The problems it causes are all to do with the crappy jumper connectors.

I did this to one which was cutting out and randomly changing tone and volume - just cut off the connectors and soldered the wiring directly to the pots and jack... it not only fixed the problems, I sure the guitar actually sounded better afterwards.

I know that doesn't answer your question

.

A bass roll-off is very simple to implement *provided* you don't mind the full bass to be at the zero end of the travel and minimum bass at 10. (Which I find logical in use anyway, since 10 is still 'bright'.) To do it the other way round, you need a reverse log taper pot, which aren't that easy to get in all sizes. Apart from that, fitting it is easy, it takes up no more space than a standard tone pot and cap.

It can't be done with the PCB though, that is one of its restrictions.

Answering questions is overrated

James’ Home of Tone have audio taper reverse CTS pots - is there a reason it should be log taper?

Log (10%) will work best, but Audio (usually 30%) will be usable.

G&L do it too. I think they use a 1M C-taper (which I think is reverse log). Might be findable as a spare part, or I have one in a guitar somewhere and can see if it has useful markings.

G&L do have wiring diagrams on line somewhere.

A quick Google revealed this - suggests it's an Alpha part. I thought the one in mine was full sized but I'm not sure that matters enormously.
