Switch to smd jfets called MMBF5457, they are much more consistent than the thru holes and much cheaper.

Me too subscribed to the upcoming mid boost to end the quest of The Mid Boost.

Yes, that was Josh's secret sauce afaik.

Can you post the voltage at every IC. Legs 1 to 8, to ground?

It's probably sandy brown. Looks like the light has a blueish hue like from a fluorescent tube.

I found the usefull range between 10 and 100nF

It was my understanding that is a part of the Foundation Overdrive concept.

Always a good combo TS > Rat. Nice pedal!

Are there still any sources to get vfe boards or at least a gerber? BTW: Nice build, Disssa. Care to show a gut shot?

You don't need 3 different 1044, the same is for 1N400x.

Don‘t get mad about them. They don‘t ship to EU either after the Brexit. Too much hassle with papers and tariffs for them. They are on easy business only. My advice: I have a friend in London who redirect my orders to Germany.

I read anywhere that the R4 resp. R8 are a bit too high with Russian Ge‘s. He recommended 68k in the spot. Anywhere lower than 7v would be okay. I got two black 416 in my stash. They have the lowest hfe readings of all my BARTs. How is yours?

White noise means there is no signal from the RM going into the FF. I see you are using thein and out stereo jacks. Just plug in a cable and check with the multimeter where the signal flows.

The CA3130 gives a nice mid push to a rat, just sayin….

If it has stabilized, put you finger on the transistor, you will see it countdown again. Spooky!

Quick! Go away and hide! This is a countdown..

Like Robert said only little improvements possible. Did you omit C12? This makes it briter and tiny bit louder. If you like the led clipping (middle position) you could a swap with the leds. The reds into D4 and D5, while use blue leds as d2 and d3. Blue leds have higher vf.

No input buffers. A FF needs a passive guitar impedance to work as intendend or a debuffer circuit with an input transformer, if you want to use it upstream in your signal chain. Old school circuit, y’know.

Yes, the schematic is faulty. It should show R4 or the trimpot, as alternative option.

To my limited experience the pot settings on the FF circuit were more important than different trannies. I swapped different tranny combos around until i found the one. My friend liked the Fuzz pot on fixed point of 80% and opted for input pot instead. This works like the smoothing out with the...
