For someone that says they don't really care for Rat's, I've sure built a bunch..... :ROFLMAO: .

Actually, I'm getting more and more into the Rat thing as I've been discovering some of the nuances beyond "in your face, dark and muddy distortion".

So this was a project I knew I had to build, if for nothing else than to keep my collection of SushiBoxFx's DIY projects complete.

Here's another one that @vigilante398 knocked out of the park! The layout was beautiful and easy to build.

I wasn't quite sure what to expect or how to wrap my head around the notion of a Rat with a tube output gain stage at the end.

But it all really works! There's a lot more than "just a Rat" in this pedal. Nathan's approach to the tone stack is an obvious departure from the Rat but it's got a ton of range. The trebles can get sharp enough to pierce walrus hide and the bass control dimed can make the room shake.
Speaking of which, there's a lot more bass frequencies in this pedal than a typical Rat. It's a very satisfying "chug" (if I knew how to chug that is heh)

There's a TON of gain on tap yet it can also sound nice with the gain turned down low as well.

Not too happy with the rattle can paint job I did on the enclosure. The couple cans of spray paint I have leftover from my "great rattle can era" are getting old and getting low. I didn't realize how much it was spitting until after it dried.

But it will do, as I don't feel like sanding it all back off.

I splurged on some aluminum knobs and mojo Motorola metal can LM308. I used my favorite JJ 12AX7 for the tube.
Did I mention how smooth the build went? @vigilante398 really has the build process for his DIY boards dialed in!

There's a toggle switch to toggle between a pair of red LED's and a pair of 1N4148 Silicon diodes. On this pedal I prefer the sound of the 4148's over the LED's.

I recorded a demo of the pedal with some knob turning but also comparing it with some of my other Rat variant builds.

Yeah man, looks and sounds good. The low end on these is petty shocking. It's not a rat, it's a nutria or perhaps a naked mole rat since they're subterranean. It competes with my favorite bass fuzz, the frantone lo-tone (which I just saw fuzzdog has so now there's 2 versions in Europe and none in the US).

At first I thought the labrat actually provided more low end but when I put it on my pedal board in the same spot in the chain after my radial tonebone and before my equilux and frequency interchange they were fairly similar in thiccnass. If the labrat had less of a power draw and didn't require me to upgrade the power supply, it would compete pretty hard which almost feels dirty to say as a "rat agnostic."
