Kool and Elfring

The Kool & Elfring ACE Boost pedal is an all tube clean boost pedal. Designed to push the first gain stages of a tube amplifier, it will yield beautiful, natural tube saturation. Adding harmonics at lower gain settings will enrichen your clean sounds and warm your tone up nicely. Medium gain settings will result in some really tasty crunch-tones. Turn it up further and experience full blown, open, harmonically rich, 3D lead tones.
