JIM DUNLOP - Ten Band EQ.
Upgraded with noise-reduction circuitry, a lightweight aluminium housing, brighter LEDs for increased visibility, and a second output so you can run two separate signal chains. With ten carefully chosen frequencies and both input and output level controls, the Ten Band EQ will let you tune your bass or guitar rig to any room in seconds. With +/-10dB of cut or boost, create earthshaking low-end, restore punch, level, and treble response to a crowded pedalboard, warm up an amplified acoustic, and much more. 18V operation for increased headroom. For ultimate tonesculpting ability in a bullet-proof enclosure. True hardwire bypass. Complete with ECB004 (18 volt) AC adaptor.
