So, how does it sound? If you've heard a demo, those are a very good indicator of how it sounds. It reminds me a lot of the Tone Bender Mk. III family when it's running at higher fuzz settings, but it does a better job of cleaning up with the volume knob than any of the Mk. III-type fuzzes that I've played. The gain control goes from a dark, fuzzy light overdrive all the way to face-melting fuzz. The filter knob has a lot of cool sounds from one end of the dial to the other, with genuinely useful tones across the sweep. Does the pedal doom? Yes, it does. Does it do Ziggy Stardust? Also yes. What about chimey cleans when you roll down the volume knob? It does that, too. The filter switches have a subtle, but still noticeable effect when the pedal is operating in normal mode, and a massive effect when the pedal is in feedback mode. The feedback mode initially seemed to be a cool gimmick, something that you might do once and a while at the end of a solo, but otherwise something that would go unused. After playing with it for a while, it's actually a much more versatile tool. It can do blasts of feedback, but when the feedback knob is set just at the edge of oscillation, it lets you get a lot of interesting textures—ring modulation suboctaves, glitchy gated fuzz, smooth synth tones, and other sounds that I don't know how to describe. It's a ton of fun to play and is a great creative tool IMHO. Building it was definitely a learning experience, but I'm very happy with how it turned out.
