Tone search! That never ending quest for the perfect tone. We all deal with it, I know. Here's where I'm at. Playing my 1985 Westone Spectrum GT, I started making a few patches on my Korg Pandora PX4B. Using the 1st compressor model set at 57 % and the 1st Valve amp model, using headphones, I have found THAT sound. Big, full and warm, yet somewhat bright and very punchy, not quite dirty, but the sweetest growl I have ever heard. Closest comparison I can give is somewhere between Tommy Shannon's tone on In Step and Eddie Jackson's tone on Operation Mindcrime, with a touch of Duff Mckagen's Appetite sound. I would like to replicate this sound with my live rig. I am currently using Hartke XL cabs; 4x10 for most gigs, and 1x15 added for the bigger clubs. These are my favorite cabs, and will remain in the equation. My current head is an Eden WT400. This is what I'm thinking I want to change. I also use a Zoom B9.1ut and have spent hours experimenting with amp and cab models, and EQ'ing, with both headphones and the rig, and I'm just not getting this tone. I'm not 100% sure, but I believe the Valve model in the PX4B is a Mesa 400+. Perhaps this is the missing link? Maybe an SVT? Aguilar DB750? Maybe GK 700RB with a good tube overdrive? What do you all think? I'm open to any suggestions on the amp that will get me the tone I have described, and so desperately crave!
