Re: Fuzz Factory Transistors?

Yes, the couple of older ones I saw around 2007 or so were AC128.

The schematic on page 1 of this thread is correct. Check that to verify. :horsey:

Hmm, it shouldn't have only a subtle effect. It's actually rather pronounced on the production units.

Yes, indeed. I "appropriated" it directly from the ProCo Rat. Specific details here: https://www.electrosmash.com/proco-rat

Re: Function f(x) Clusterfuzz [traced]

To get a little more treble response from this pedal, would I just change the input capacitor? output cap? What capacitor in the tone area would I play around with to change the effect of the tone control? Any advice? Reduce the value of the smaller Filter switch cap (4n7) to something like 1n...or...

Re: Function f(x) Clusterfuzz [traced]

In the demos I have seen of this pedal there doesn't usually seem to be a huge volume drop when they switch to the 2 Si options. Any thoughts on what the cause is here? Either they adjusted the volume in editing, or they have some kind of automatic level control going on. There is a MASSIVE volume ...

I'm not a huge fan of board-mounted footswitches for production pedals, but otherwise this one looks like a pretty tight build.

Re: Triton Delay - Adding the "Glide" from EchoCzar to PT2399

Yep. Basically it just uses the R/C filter as a "bleed off" of current from pin 6. The time it takes to switch from one to the other is a function of the frequency of the R/C filter.

Re: 2020 forum updates - work in progress

First of all, great job on the upgrade! It's sooooo much faster. :thumbsup Hello modman, great job on the improvements and updates so far! If possible, I have a little request for one of the next sets of updates. Do you think that the time that is allowed to make changes to a post (edit a typo, chan...

Yep! The purple one is UV printed. The other one I laser etched. It’s easier to etch or print first. At least for me.

Re: Function f(x) - Gate Crasher

Ah, I figured R1 could be the pulldown, because the signal has to come from the relay to go to the 4049. C1 might also go to gnd at the input. Correct on both. What you have drawn is almost exactly right. The few variances won't make a difference in functionality, but might change tone slightly. Do...

Blend? Dials the in the amount of octave Correct. so there is no "drive" control, but also no leftover 1M, if one of the is used as a pulldown (maybe not) :scratch: There is no control of the input gain directly, correct. It's fixed gain with the feedback resistor set to 330K. There is a ...

Re: Function f(x) - Gate Crasher

Not a bad guess! :mrgreen: You've got two square wave shapers in there, however. Only one is necessary. So either keep the 4049 setup as is and get rid of the first XOR gate, or keep both XOR gates as drawn and get rid of the second and third inverters. You'll get the same result (more or less) with...

I'm a big fan of OshPark, but have you ordered through JLC PCB? The quality is quite good and it's insanely cheap (even with expedited shipping it's cheaper than OshPark).

Triton Delay - Adding the "Glide" from EchoCzar to PT2399

Did this one a while back but thought I'd share here. I took the basic bones of the Deep Blue Delay (changed some filtering values), added a variable LPF on the delay output (via trimmer/cap), added a second Delay Time control with a slow transition when switching between Time 1 and Time 2. It works...
