The Pre-Owned Pigtronix Resotron Analog Tracking Filter (18v) is not your average pedal — this is one of those wild, character-heavy bits of gear that turns a simple guitar signal into something seriously expressive. If you’re into synth-like textures, envelope filters, or just pushing your tone into new territory, this thing goes deep.

At its core, the Resotron is an analog tracking filter, which means it doesn’t just react to your playing — it actually follows the pitch of what you’re playing and shapes the filter in real time. The result is a much more musical, responsive effect compared to standard envelope filters. Notes feel connected, almost vocal, and you can get everything from subtle movement to full-on synth sweeps.

You’ve got a lot of control here too. The pedal lets you dial in filter type, resonance, envelope response and sensitivity, so you can shape everything from funky auto-wah tones to sweeping, almost modular-style filter sounds. It rewards a bit of experimentation — and once you get into it, it’s seriously addictive.

Running at 18 volts, it’s got plenty of headroom, which keeps things clear and dynamic even when you’re pushing it. That extra voltage helps maintain definition, especially if you’re using it with hotter pickups or stacking it with other pedals.

Being a pre-owned unit, it’s a great chance to get your hands on something a bit more unique without going full retail. These aren’t your everyday stompboxes — they tend to find their way onto boards where players want something a bit different.

At Musicmaker, this is the kind of pedal we’d point out to someone who’s already got the basics covered and is looking for something more adventurous — something that reacts, inspires, and maybe even gets a bit weird (in the best way).
