This is the highest gain fuzz we've ever made. We got to "10" and thought--let's go past 11 and make it 12 or 13? Why not? The treemolo side also has some additional gain to drive your amp, the fuzz, both, or whatever else you have on your board. The treemolo side is smoooooth and subtle, surely to remind you of classic 60's tremolo sounds. You can use each effect independently (true bypass of course), both at once, and even pick the order of the two. This effect was designed for The TONE MOB and is only available in The Tone Mob Store.
We always recommend isolated power supplies. If you daisy chain effects on one supply you may inject noise, ripple, ground loop hum, etc. This effect requires 9v, center negative power. In other words, the industry standard power supply.
