The Keeley Manis Overdrive uniquely combines both germanium NOS transistors and diodes for more compression and saturation plus a 3db bass-boost makes it unlike any other mythical Klone! The Manis is Hard Clipping “clean boost” using Russian transistors as germanium diodes. Ge-Trans Switch – Diodes or Transistors – Huge difference in feel with increased saturation and tube like compression. The Bass+ Switch – Lowers the frequency response by one octave and then pushes 3dB harder. True-Bypass or Buffered Bypass/silent Switching – Whichever works and sounds best in your rig. • MFSKU KManis • UPC 810026442025
