Up for sale, a 2012 147 Pedals envelope filter in good working order. This one-off pedal is a variation on the original MXR Envelope Filter design and was even built into a vintage MXR enclosure! Using the Tonepad A-gua Filter schematic, this 147 pedals creation adds a Sweep two-way switch to the original Threshold and Attack knobs. Very responsive to your pick attack, this pedal creates some sweet, vocal, and funky sounds, with a sound analogous to an auto wah.
The enclosure shows some dings and flaking of the finish, and 147 pedals added a smattering of postage stamp graphics on top of the white basecoat. The pedal works as intended and will run either on a 9v battery or power supply (not included).
