It's old, but I think it's a rare model. It produces sound normally, and the rubber on the back, which often goes missing, is somehow holding up. What's noteworthy is its distortion response; rather than a so-called high-gain distortion, it reacts more like a Fuzz Face, if I may be so bold. At full volume, it distorts quite thickly, but when you roll it back a bit, a shimmering component mixes in, allowing for operation with a nuance similar to creating a ringing sound with a fuzz. There's a fair amount of noise, but it's an old model, so it can't be helped... Feel free to ask any questions in the comments!
