The AMT SS-11 3-Channel Dual Tube Guitar Preamp boasts minimum size with maximum functionality for full tube overdrive using the highest quality components. The SS-11 is brother to the SS-20, but designed to be different. While the SS-20 is the more aggressive "METAL" pedal, the SS-11 was intended and manufactured for that famous CLASSIC tube driven over saturated guitar tone that eveyone loves and craves. 

Description of SS-11 Channels: 
LEAD channel provides thick, viscous sound for playing both chunky rhythm parts and singing solos with excellent presence. TREBLE SHIFT toggle takes your lead sound into bright mode, similar to the good old "Treble Booster" pedals of the 80's that guitarists used to enhance their solos. 

OVERDRIVE channel features a more open structure of the sound. This is the SS-11's sweet spot, offering tubey and saturated sound, much like that of the classic tube amps of the 70's and 80's. A wide range of sensitivity adjustment results in the sound starting from light crunch to thick and bright lead channel-like sound with real tube tone. If you're looking for something other than that dull sounding solid-state OD or TS clone sound, then this is it. 

CLEAN channel focuses on crystal clarity clean sound. Low, Mid, and High controls for tweaking your sound; as well as and TREBLE SHIFT toggle for adjusting high end response.
