Functionality confirmed. This is a so-called TS-type pedal, but it's simple, versatile, and easy to use across all ranges. It sounds great even with the GAIN set to zero, and the crunch sound is classic. The lead tones when you crank up the GAIN are incredibly satisfying. It distorts beautifully on its own, without the need for a booster. The full-bodied mids cut through without getting buried, which is a characteristic of Jimmy Wallace pedals. The pedal has been aged, giving it a vintage look and feel. Highly recommended for those who want instant distortion! Used only at home. I've been busy lately and haven't had much time for my hobby, so I'm selling it because I haven't been using it much. Please note that there may be some scratches, as it has been aged from the beginning. Thank you.
