For some time I've been curious about Sean Michael's 4-knob Deluxe pedal. I have a Les Lius, and I love it. And I really liked the idea of a brown Tolex-type sound in a box. This pedal delivers the goods. It's a low-gain pedal, but I've come to realize that this is what I like: something that sounds like it's pushing the amp to the edge of breakup, but not into full saturation. The High Powered Tweed Twin setting does that on the Les Luis. And this 4-knob Deluxe does it while offering a slightly "browner" sound. One of the things I really like about this pedal is that it has knobs for treble and bass (bottom), in addition to volume and gain (top). If Lovepedal can be faulted for anything, it's probably for having too little control over the contour of the sound of many of their pedals (including the Les Lius). Not so with this one. I often hear people say of pedals that they can make your amp sound overdriven even at lower volumes. That is, you don't have to juice the amp to get it to sound juiced. I thought that was pretty much bunk. Well this 4-knob Deluxe does it. Really. And it's not only about giving you an edge-of-breakup sound; it also provides the touch sensitivity that normally only accompanies amps at high volume. I have not experienced anything like that from a pedal before. I ran this through my 1976 Deluxe Reverb with a SSS Strat tonight. Amp volume on 3.5, and the pedal at the settings below. The guitar responded like the amp was on 5, and the sound was tremendous. Volume just below noon. Gain about all the way up. Treble at 1-2 o'clock, and bass at noon.
