The goal was to bring back one of my favorite features, the Low Mid EQ control as well as allow for additional control over more aspects of the circuit allowing you to dial in just the right flavor of HM2 style chainsaw for your sound.
Pre v2.1 - The original ran at 12v so if you find it too nasty at 9v, go with a higher supply voltage. I personally use EQ Only mode while plugged into 18v the most.
July 16th, 2023 - v2.1 - Updated sweep and range of Clip, EQ controls, and adjusted gain structure so it's not quite as gnarly but better for users without a 12v supply.
CONTROLS
Name Location Description
Level External Controls the output volume.
Blend External Mix between 100% buffered dry signal and 100% wet signal to bring back the dynamics of your clean signal.
Clean External Adjust the amount of gain on the dry signal side of the blend.
Gain External Controls the amount of distortion.
High External Cut/boost the treble frequencies.
Mid External Cut/boost the high mid frequencies.
L.Mid External Cut/boost the low mid frequencies.
Low External Cut/boost the bass frequencies.
Clip External Adjust the amount of hard clipping saturation. Stock HM2 is full CW.
EQ Only External (footswitch) Toggle between the HM2 gain and a clean buffer to use the pedal as just an EQ platform. Does not work if pedal is in bypass.
Gate External Adjust the threshold of the coring circuit diodes for noise reduction.
This is a modification of the HM2 coring diodes, don't expect it to work as an intellegent gate such as Zuul or Decimator.
Frequency Center Shift Internal (trimpot) Sweep the center frequency of each EQ band individually. M.Q adjust the Q width of the Mid Frequency. Stock setting is ~noon. Q width is CW for narrow, CCW for wide.
Bypass LED Brightness Internal Adjust overall brightness of front LED.
Default setting at minimum (full CCW).
POWER
9-18VDC - CENTER NEGATIVE
This product can accept up to 18VDC supply input for additional headroom.
9v for real nasty, 12v for the OG sound, 18v for smoother and higher headeoom. 18v recommended if youre normally running EQ Only. Powersupply not included. .
CONSUMPTION 17mA
SWITCHING TRUE BYPASS Soft click (1.1KGf) mechanical 3PDT.
