I've looked at a couple different options to get a little more 'grit' out of my gear. I'd jammed w/ the SVPCL a bit before buying mine, and still completely dig the tone I get w/ this pre. That being said, I'd like to get just a little more growl from it, and it looks like getting a boost pedal going into my pre ought to do the trick. I've looked at a few different options in the Effects forum, and thought I'd see if any of you might have some input. So far, I'm inclined to look at the Fulltone FB-2 Fat Boost, but am definitely open to other options. Typically, I'm using the "#4" setting on my Ultra Low (contours the sound to emphasize the low end like the original SVT), no bright, no ultra-high. I keep the crossover on both of my cabs turned down, at approximately 20%. The tone I'm going for is akin to Mel Schacher's tone on the early Grand Funk Railroad, also Johnny B. Gayden on some of the Albert Collins albums...not a wildly overdriven "N.I.B" growl, just a burly, ballsy drive. Thanks for any and all suggestions, much appreciated!
