I've tried and like their 2-Conductor Guitar wire and their 4-Conductor Guitar wire. I've used them in guitars and pedals.

Cables? Have you checked for DC voltage distribution on the PCB? (Is the proper voltage getting to the chips and is the VRef present & correct?) Have you double-checked the component values and orientation? Have you tried an audio probe?

I'm quite happy with and fond of LoveMySwitches' "24AWG Pre-Bond" (stranded). Seems to be identical to what Barry was selling at GuitarPCB. For specialty wiring, I prefer to use Remington Industries. They provide some nice selections of small gage shielded wire too. All at decent prices.

It doesn't get squishy to the ears like the X100 in clean mode. It's far more subtle in this circuit. It's important that the JFET's Vgs(Off) value measures -1.00V, ±0.15V

This circuit is the Dunlop version (Blue Button) of the Acoustic Guitar Pedal. And with the JFET bias section they used, it extends the range of Vgs(Off) selection from -1.00V ±0.05V to -1.00V ±0.15V without the need to futz with manually selecting the bias resistor values. The comp in this...

Woot! Nice work!

The called for charge pump is a TC1044SCPA. The "S" in the suffix is important for this application.

IMO, BJT selection does make a difference in FF circuits. Primarily between silicon or germanium. Silicon BJTs will typically be rather consistent in a FF circuit. Whereas germanium BJTs will always exhibit a temperature sensitivity that silicon does not. From day to day, or even hour to hour...

T'was a general reference. Not seen any real personal attacks here in this forum. Pointing and laughing is still OK; right? ;)

TBH, I get the impression we're all Bozos on this bus. As for tariffs, (my opinion is mine and mine alone), I suspect our president is playing the long game. He even said at different points that it might hurt certain businesses in the beginning, but they would eventually level the playing...

IMO the limiter section of this circuit is far more subtle than a dedicated limiter. A decent, dedicated limiter typically has three main controls: threshold, release, and output ceiling. But it should still do a trick.

After meticulous tracing both the Rockman (SR&D - gray button) Acoustic Guitar Pedal and the Dunlop Acoustic Guitar Pedal (blue button), and all the heavy lifting in KiCAD for PCB layout work from @rwl, we've accomplished a working PCB for this oldie goldie. We went with the Dunlop blue button...

Another nice surprise from @Robert. The "Closed Circuit Booster Limiter". Who knew such a great utility pedal existed? Not me. Anyway, here's my build out of it.

IN is the logic input and ought not be left floating. "COM", "NC" and/or "NO" can be left floating - those control the signal path. "IN" is the logic that toggles the switch.

Right, but I didn't go there for these builds.
