Re: STC-3a alternative wiring?
Hey badfunkn. Thanks for the post and welcome to the SD UGF.
How were you thinking of wiring your controls? (a) volume / slap; (b) pan / midrange; (c) bass / treble? I guess it could be done, but we don't have that harness wiring available. You'd need to get a custom made harness. And source the pots. Sounds like a hassle to me. Sorry.
I think the easiest alternative would be switching to the STC-2a preamp. It's optimized for a three-control bass: (a) volume / slap; (b) pan; (c) bass / treble. Sure, you lose the mid-range control, but you don't have to worry about a custom harness and finding those weird stacked pots.
That's my advice.
