Doh...been having some flakines w/ the output on my toby pro-5 over the last week. So I cleaned the output jack and replaced the battery...and then it totally poops out. I didn't have time last night to totally dig into it, so I'll check for broken wires / Cold joints tonight. Prolly broke a lead to the battery. But...if that preamp has toasted, I'd really dig replacing it with a new preamp. I'd love to use the basslines 3 band setup w/ the slap contour (I have one in my warmoth). But, this is a two p/u bass and my warmoth just has a MM p/u. So the blend is kinda unknown to me. The stock knob config is a 4 hole, and I'd rather keep that the same. The master volume knob will be the slap contour...so that's Push/Pull. The Treble control is a single, and the Mid/Bass is a concentric...so no prob there. I'm guessing the p/u blend will be before the signal goes into the preamp (just acts as a single input). So, basically, does anyone have a good quick place I can go to check out how to make the 4th pot a blend config? P.S. This isn't a total bad thing, it just made me get out my T-40 and realize that it sounds very very tight w/ the SVP pro. Damn that thing has...well....toughnuts lol. It's a big output growly groaning breathy dirty thing.
