And particularly the troubleshooting process laid out by playsforfun. It’ll take me a while to get what I need and run through the steps, but I’ll report back once I have.

Cheers,
Mick

Sorry for the delayed response. Had other priorities unfortunately.
Anyway…
re: playsforun, I’ve post two new pics of the wiring per your suggestions.
re: brd, I know the boost section is working but have tried every possible order of the 3 wires on the common lugs of the on/off switch with no success. Also worth noting that the boost…Read more

I tried the suggestions that playsforfun offered, but it’s not working. However a slightly different result than the first one.
The on/off switch still does nothing (LED comes on). Just bypasses the signal. However with the Boost switch on, the master volume, tone and overdrive work (as you’d expect) but the boost level pot…Read more

That’s very helpful. I’ll wire it up as described and see how it goes.
re: power for the boost LED, there is a trace on the dual FS board that runs across from lug 2 of the boost switch to lug 2 of the on/off switch. When I apply power to the board, I get 9v at those lugs so I’ll try that after I get the FS’s functioning.

I’ve attached a photo of what I’m working with. I have two 3PDT pcbs, but assumed I only need the one (shown on Boost).
The 4 wires coming off the main pcb would presumably go the corresponding points on the switch pcb (V+, Gnd, From, To) (labels on main pcb on other side) but I’m at a loss as to how the two switches are…Read more

I built a Full Drive kit from Tayda but I’m having trouble with the switching circuit.
It uses a separate pcb for the dual footswitches (on/off & boost). Unfortunately there seems to be a problem with the switch pcb.
There is bypass signal, but the on/off switch does nothing and when the boost switch is engaged, it mutes.
I’m sure it is…Read more

I guess swapping chips is technically a mod, but it almost doesn’t feel like it because it’s so easy to do (providing they’re socketed).
I don’t have any problem removing/replacing them, and I didn’t even know there was a tool! (apart from me!)

I’ve had that “life of pots” article bookmarked for about 20 years! I’ve referred to it ma…Read more

Firstly, the pedal sounds GREAT! I used to have a “68 Pedals” clone (Hong Kong) of this and I have always regretted selling it. Now I have my own!

I will get into the sound and what I changed a bit later, but one thing I would like to…Read more

Pretty happy with the tones. The differences in clipping are most subtle than I expected, but are certainly audible.
I’d be interested if anyone has done any tweaks to this design that might be fun to try.
I only used a socket for…Read more

I’m just using the red LED that was included in the kit. It’s just an opaque red one. I have no idea what the mcd brightness is but it’s not like some of the water clear coloured ones that will burn out your retnas!

I also have used a 10k CLR with some other pedals, but I’ve tested the kit one with a 1k8 and a battery…Read more

My kit came with (2) 1k8 resistors. R19 is the only one with that value (which I presume would be for a main board status LED).
If I’m using the 1k8 on the mini-board as the CLR, I don’t need anything at R19, right?

Some gut shots…Read more

All went well with the exception of not reading about the fix for the “toggle makes no difference” issue in the forums.
After diving back in, I changed R5 to 220k as Barry suggested, and it works much better. Still a bit subtle but absolutely can hear the difference, and I like…Read more

I’m contemplating an external switch instead of the DIP, but not 100% there yet.
I’ve seen some other posts detailing the wiring for it. More research to come!

Cheers,
Mick

New member and beginner BYO pedal guy here. I’ve only built two pcb-based pedals so far (Angry Charlie clone and Crunch Box clone – by other supplier).
About to start the T-Drive kit but having trouble finding a clear-cut description on the DIP switch operation. eg: 1 On / 2 Off = ???, 2 On / 1 Off = ???, 1 & 2 On = ???, etc you get the…Read more
