Guitar pedal effect. Limited to 1500 units worldwide, Black Ash is a fuzz/overdrive that takes some cues from the vintage “three-knob Bender.” It uses a highly curated cache of rare and irreplaceable components including paper-in-oil capacitors and NOS half-watt carbon composition resistors from EQD President Jamie Stillman’s personal stash to light a fire under this classic fuzz/drive with an explosive-yet-detailed treble response, a sturdy midrange, and subterranean bass extension.
