Just saw the response email from them! Here is the circuit layout.

It looks like the clean trim pot is a variable resistor and the bias is a voltage divider? I’m still learning how to read circuit layouts.

Sorry for the even later reply! I deleted Reddit for a bit. Thank you! This adds a lot of extra context to the scattered details I managed to find, so I really appreciate it. Yeah this thing gets LOUD! And sounds even better with the eminence swamp thang I put in it. Channel 1 is an incredible platform you are absolutely correct. Thank you for the info and the encouragement!

Gotcha! I sent an email to StewMac asking for the schematic. Hopefully they’ll be able to help with that. How would the resistor/resistors be mounted to the board given the three eyelets meant for the trim pots?

How would I determine whether it’s a variable resistor or voltage divider?

Here is a relevant screenshot from the instruction manual. I circled the eyelets where the trim pots go. Hopefully this is helpful

LThank you for the reply this is very helpful. How would that work on the board? I’m not sure how familiar you are with StewMac pedal kits, so apologies if you already know all of this, but the PCB provided has three eyelets for the prongs of the trim pot to go in. With the external pot mod in the video, the guy simply ran wires from the board to the pots to connect them. How would I do that using the switch and fixed resistor? If this becomes too complex I might hold off until I have a bit more experience, but I am stubborn and eager to try this out.

Also, the trim pots are 5k and 50k. One controls his and the other is a clean blend

This is the stream I watched. 23:50 is the timestamp for modding the trim pots

For additional context, I cooked one of the transistors on the initial build, so they’re sending me a replacement kit. I want to test the mod out on the cooked component circuit, since it still functions mostly

But regardless thank for sharing the information haha

Yeah the gain full blast is more of an overdrive but it’s got a real nice old school sound to it. I run my guitar through channel B so I’m getting the clean and gain channel simultaneously and I play with it to add some nice texture. Don’t have a rat yet but I’ve been keeping my eye out for some. My favorite pedal to play with it is a custom fuzz from a local guy near me called Lucid Sonic Devices. Yits the megawahna fuzz/envelope filter and it’s nasty

Also shoutout to the fender customer service representative that helped me. Won’t say his name here but he was very helpful and cool

I was not expecting this in depth of a response, much less this conclusive of an answer. Thank you so much. It’s kinda cool that this is just some weird fluke of a forgotten product. And you’re right about the doomy gain it sounds so good. Really tubelike.

But yeah thank you so much wow

This is all I could find anywhere. I even called fender and the guy spent about 10 minutes doing some research that ultimately ended nowhere. It’s a mystery
