Used, in excellent condition. Complete with box. Reissue of the classic DOD envelope filter, giving your guitar sound a funky quack. The addition of the up and down switch gives you the option of deciding which part of the signal to emphasise, the "UP" setting gives a more classic filter sound while the "DOWN" option is ideal for bassists by emphasising the lower frequencies. The Level knob lets you adjust the DOD Envelope Filter 440's sensitivity for a dynamic response to your pick attack. The Range knob, meanwhile, controls the range of movement in the envelope's sweep. Unlike the original, the DOD Envelope Filter 440 is now true bypass so it won't colour your tone when disengaged. Postage options listed for UK only. If you live outside of the UK and are interested please don't hesitate to get in touch and I'll add the postage option for your area.
