Dual-Harmonic Boost

The Echopark Dual Harmonic boost unit.

This is our 2nd version of the Dual Harmonic Boost.  The same legendary “Dual Stacked” OD, but modified with OD boosters on  each circuit for a “Maximum” OD. The center “tone” Pot has been replaced with a “Master Volume”, allowing you to crank both OD’s  for maximum distortion, at lower volumes. Because of the “Insane” Overdrive, the DHB2 has a 3 Way “Tone Control Switch” ranging  from (Far Left) Low, (Center) Med, (Far Right) High. This switch can  be used to filter out unwanted frequency feedback at higher volumes, or a tone cut for playing certain styles of music. Far Right  Knob is OD Gain BOOST 1, Far Left Knob Controls Gain on OD BOOST 2.
