Analog Man Block Logo Envelope Filter Pedal

Get your funk on!!

Analog Man's Block Logo Envelope Filter starts with the 1970's classic MXR circuit, and updates it with modern benefits.

In 2017 they finally finished our high-quality circuit board to make more of these, with a better layout and cleaner build than before.

They previously made 100 using real New Old Stock (NOS) MXR circuit boards for original sounds, but they added the third knob and toggle switch so you could get more tones. The UP/DOWN toggle allows those Mutron type reverse Wah sounds. The EMPHasis knob allows more or less extreme tones. Most of these modifications were discovered by the guys on the diystompboxes forum, like Mark Hammer and Steve Giles. Their new circuit board is the same circuit, but should be a higher quality built pedal as it is designed for these mods and had better shielding.

Also they added an LED, a True bypass switch, and 9vDC power jack.

Very easy to use, unlike many envelope filters which are difficult to set for easy triggering. All knobs at noon usually sound pretty good, then adjust to taste by ear.

SIZE: 2-5/16" x 4-5/16", original MXR size 1290/1590B enclosure.

Uses normal 9Vdc power or battery, very little power, well under 10mA.

This pedal is not as "synth filtery" sounding as the Mu-Tron, maybe more like an auto wah.

As usual, they do a little tweaking to make the pedal more usable. They put a blue trimpot inside on the circuit board, so you can adjust the envelope for different guitars.

Turned all the way up (clockwise) it's exactly the same as the old MXR and works great with weaker pickups like single coils. They normally set it turned down a bit, vertical, to work better for humbuckers or allow a deeper sound with single coils. You can turn it down further to get lower frequencies, even sort of "sub-bass" frequencies that are cool on bass guitar!

Works fine into dirt pedals, even a germanium Fuzz like the Analog Man NKT Sun Face, as it's output impedance is fuzz-friendly.

BASS GUITAR: With the toggle UP and all knobs at noon, it sounds good on bass. You still hear the low end and normal note, like a clean blend, with the envelope filter sound on top of it. You can use the internal trimpot with the toggle UP to get some deep, cool sounds. With toggle DOWN on bass, you get a more intense effect without as much of the normal sound.
