Finally after months of research I was able to check into the geetar shop. After much anticipation, I finally played the SVT-VR (which is great, but not as good as the real deal), but more importantly went on a fuzz/od/distortion spree! Here are the pedals I tried: 1. EBS MultiDrive 2. EHX Big Muff 3. EHX Sovtek Big Muff 4. Pro Co Rat 5. Ibanez TS9 Tubescreamer 6. Visual Sound Route 66 American Overdrive I also wanted to play the Marshall Guv'nor, the Metal Muff, and the Little Big Muff. Of the three, they only had the Metal Muff, but I didn't need to try anything esle once I heard the Big Muff. Damn, there's not a SINGLE tone on that thing that doesn't sound great, no matter how high or low the tone knob is. It's like a smooth, rich, buttery chainsaw (funny, right?) that translates so well to bass. Even with all the rave on TB, I was skeptical because I heard it on guitar and I didn't like it. I really need to look no further. This is the one. Comments on other pedals: 1. Pro Co Rat: Breaks up more than it sustains. Great sounding drive, but not so versitile. I can see why this pedal has love/hate reviews. 2. EBS MultiDrive: Somewhere between the Rat and the Muff with breakup/sustain. Pretty versitile with three different settings (standard, flat, tubesim). If I ever felt the need to have 2 ODs, I would strongly consider this one. 3. Sovtek Big Muff: Crap. Sorry, but I got nothing out of it. 4. Ibanez TS9 Tubescreamer: Sounds kind of cool. Thin and trebly with very little low end retained, but I can see someone wanting to use a sound like this, just not very often. Reminded me of Flea's "All Around the World" tone. Not exactly, but pretty damn close. 5. Visual Sound Route 66 American Overdrive: Definitely the most transparent of all the pedals. Great tone and sustain and very tweakable (compression & bass boost). Personally, I think the transparency made this pedal a little too tame, but I can see many people digging it. Next to the Big Muff, there's no contest. Many came close and many were more tweakable, but why get something that sounds almost as good, and get tons of different "almost as good" tones, when the Big Muff sounds great at every setting with just 3 incredibly useful knobs.
