Another Rat, because that's all I know how to do. Built on a pair of DirtMonger MultiRat boards, and housed in. Deucetone-style enclosure. Brutalist knobs, cuz duh. Soft touch mini DPDT footswitches

The right-hand side features a Soviet UD1408A, which is a slightly darker, less gainy take on the LM308.
  1. Soft clipping - LED (Soviet metal n glass)/ None / Symmetrical Silicon (KD522B)
  2. Hard clipping - Germanium (unmarked) / LED / Silicon
  3. Shift - 47uf / 2.7uf / 6.8uf. the toggle throws the bigger caps in Parallel with the 2.7u to approximate the Juggernaut and FatRat cutoff frequencies, respectively
The left side features a NatSemi LM308
  1. Soft clipping - LED (square reds) / None / asymmetrical silicon (1N914)
  2. Hard clipping- LED / None (Clean Rat) / Silicon
  3. Shift is the same as above


Both sides include my typical tweaks to slightly tighten and fatten up the traditional Rat -
  1. R9 increased to 2.2k, C11 increased to 4.7n, and Filter reduced to 50kA to limit the range to what I consider it's most usable limits
  2. R7 decreased to 470R to slightly increase the gain and raise the cutoff of the lower pole
  3. C5 increased to 2.7u to slightly lower the cutoff of the higher pole
  4. C3 & 12 increased to 27n because I have a glut of them
  5. C8 decreased to 27p to let a lil more high end hash through and allow a bit more room before the chip starts collapsing with higher Distortion settings
  6. Distortion is 100kD for a more gradual increase than a typical Audio taper. I've also added a 1k between lug 1 and the board, so it never bottoms out into a buffer

It's a Rat. It's two Rats. It's rad. The DirtMonger boards are awesome
