Hypervintage Fuzz
A fuzz made for sonic titans and explorers. Using the same vintage transformer as the original, this octave harmonic tone generator is as unique as it is useful. Based upon the venerable and vintage Maestro Brassmaster with some modern conveniences, the Greenseer excels on bass and does very interesting things to 6-string guitar.
On bass, it runs the gamut from slightly-wooly warmth to all-out doom apocalypse, and might be the only bass dirt you ever need. A specially-designed circuit ensures that you don't lose lows and retains clarity of signal while wrapping your bass tone in a fuzzy, ripping tone jacket. Tired of muddy bass fuzzes and losing your low end? This is for you.
On guitar, the Greenseer is a whole different beast. At its core, it is a vintage fuzz in the spirit of the sky (wink). It can spit, oscillate, and squeal on solos with the best of them. However, it works great stacking with other dirt, especially into overdrives, and almost immediately goes to heavy territory when doing so. Think of it as a fuzz enhancer for the rest of your dirts!
