if you have anything between 33r and 100r it'll be fine. The Rat for exemple uses a 47r there I think. Pretty standard value.

D taper? 🤔 Yeah without knowing anything Id try a 47k or 100k resistor between lug 2 & 3 of the pot and see what happens. And if its doesnt change anything try the same thing between lug 1 & 3.

Whats the taper of the pot? Lin (50kB), log (50kA)?

A pseudo tape echo that I love is the old Ibanez EM5 that uses the M65831 chip. I’ve been thinking about building one but with a PT2396 (that can replace the M65831, omitting a couple resistors, according to the datasheet) and a modulation section. Im sure it’d be an excellent candidate for a...

I like it with C5 on a switch. About 20-30% less gain, so if you’re into low gain you’ll probably like it too Also I usually dont populate C10.

Isnt the Fulltone a clone of the Echoplex EP2?

Its a good gain pot value. Log is better than lin. The Timmy v2 used A1M. Go for it!

Yep, I was about to say the same thing!

Haha well done

I cant tell if you’re joking or being serious :)

There already is a feedback section in the Ghost Echo. If yours doesnt oscillate when you crank the « dwell » knob, try and reduce R8 (22k) :)

Yes, an audio probe is easy to build and extremely useful. Did you already post voltages? Does the treble pot work as expected? Could you try a pair of back to back diodes (germanium or schottky - bat46, bat41) in parallel with one of the Ge diodes? Just to see if you get distortion with a...

Dual 100kB for gain, 10kB for treble yes :) A = Audio / logarithmic B = linear

I always use A10k instead of B10k for volume in a Klon for that reason. You should try it :)

Very nice build! I wonder about the HPF section of the pendulum. It seems the cutoff frequency is 1950Hz, which seems very high, as I remember both the Cardinal and the Twin Peaks tremolos use a cutoff frequency of about 750Hz The LPF section seems a bit more standard (400Hz, the cutoff chosen...

Hey, sorry Im not gonna be very helpful, I can't remember what I did, and I didn't take notes. I think I based the electra circuit on the JTM from tagboard, don't know if it's the same schematic as the pedalpcb one. Maybe try and change the diodes to diodes with a higher threshold, like 1N4148...

Hey! Sorry I didn't reply sooner, glad you found the answer :)

Love your dedication and passion, thanks a lot for that! Yeah my rational mind has doubts about the sonic difference with the resistor change but who cares! I love those conversations, and that you're so passionate about creating the sound in your head. (With that said, I would love to hear...

Funny I was also thinking about that Paul C message on thegearpage or the madbeanpedals forums! Totally agree with your message. This small HPF change should be absolutely inaudible.

what did you use for input caps? 10n or 22n?
