Ok, thanks to Induction's invaluable help, I have finally got this to a stage I am happy with.

I have changed R5 on the schematic (the left hand one of the two 47k resistors on the layout) to 33k. The right hand one is unchanged at 47k.

I am now getting a steady 5.52V on pin 3 on the IC. It does sound better as a result.

I have used KD521V clipping diodes, which sound best out of all the diodes I tried.
I did try 3mm red LEDs as well. Some builders say they sound great in a Mongoose, but personally, I did not like them - seemed to rob it of character.

I tried a load of transistors, before settling on ME4003 as my favourite. Metal can 2N2222 sounded great too, but not as smooth, and took away a little of the bass.

I know it is a alternative take on a Rat, but it does not sound like a Rat at all - far less spitty and farty. IMHO it blows a Rat into the weeds on every setting.

It's also really versatile. It can nail that Gossip "Heavy Cross" driven funk sound, and at full drive is pure Kevin Shields (not suprising as he uses one), and makes a great Stoner/Doom pedal.

Don't like Rats - build one of these instead. It's awesome!


Now on the Giant Hogweed!
