Proco Turbo Rat - verified layout

I was surprised to see that was no layout for this on the main page, mirosol does mention the RAT2 could be modded for this but that information is incorrect.

I've used GGBB's Multi Rat schematic for reference for this layout, the Turbo RAT is basically a RAT2 but with 5mm LED clipping and the Gate resistor is raised to 2M2, and then a 2M2 resistor is added between Drain and Gate. On mirosol's RAT2 there was no way to add the 2M2 between G & D, so I made a new layout using his as reference, moving a couple of things around it came out at 18x12 with one column added compared to his. The clipping LEDs light up when you play if you wanna get creative for your enclosure.

Descrition from Effectsdatabase.com:
The Turbo RAT is the most intense pedal in the RAT family. For those brave enough to harness its power, it provides a palette of distortion unequaled by any other pedal. This is why it has been a main ingredient in the post punk/indie rock movement of the past twenty years. Boasting more than twice the maximum output of the original RAT, the Turbo RAT is hard-clipping while the mid-range frequencies are slightly scooped. With a less compressed signal, it also has a brighter tone, so you'll have no trouble being heard through the mix. Since this pedal was designed around the musical distortion that made the RAT famous, it retains these qualities without sounding harsh. The Turbo RAT features the legendary RAT Filter control. Turn it to the right to roll off brittle high-end frequencies. Having trouble cutting through the mix? Turn the Filter down and allow the natural brightness of your instrument to shine through. The Distortion and Volume controls dial in the perfect amount of gain while keeping the level consistent with your clean tone. While there's no mistaking the legendary RAT tone when the pedal is on, true-bypass switching ensures that when the pedal is off, there is no coloration of your sound.

Okay, I added a different demo video because I found out that the newer versions is just the regular RAT circuit with 5mm red LEDs for clipping, and not knowing if the other video was an old Turbo RAT or a newer I found a video that said 1990, so that would be correct for this layout.
