Does anyone know if it is possible to perform the "gambit mod" on the new ATmega48 version of this pedal? I was prodding around at shorting some resistors but couldn't find this result yet: https://www.youtube.com/watch?v=gNHh_yVZyAE I, too, would love to know if the gambit mod is possibl...

This is very cool!

Anyone have a recommendation for a 4 wire connector set used to link a footswitch pcb to the main pcb? Typically I have seen one mounted on the main pcb & the other used on 4 wires coming from the footswitch pcb. Part numbers & vendor would be appreciated. Maybe these? http://www.taydaelect...

Hey Dino! Is that a 1590bb enclosure?

Is Q2 a 5088, or will any small signal PNP BJT work? According to the schematic I have from Tim, it's a 2N3906. That's what I have in my two builds. The info below was also included on the original schematic. For best octave effect: R8, R11, R14 and R15 - Match to indicated value. D4 & D5 - Mat...

Did anyone ever end up creating a vero layout or PCB for this one? I can't seem to find a layout, specifically the FZ-2 (not the FZ-3, which is IMO very different-sounding).

Okay, looks like Q12 was bad, breaking down under load. Replaced it and signals look a lot better with higher output. have to wait until I get home to try it, but it looks like that was it. Awesome! This is one of those pedals I wish hadn't "disappeared" from my possession. One day I hope...

Happy you like it mate, thank you for giving it a go. I am slowly working on a refined version. Do you use the true bypass layout, or the original not true bypass? The not true bypass version pops a little for the first couple of stomps; I had no probs for the true bypass version, but I use a split...

Very proud of this shitty thing... gives around 170 msec of delay (you have to use the "less time" trimmer to set a max time delay without bbd whining) with repeats and even self oscillation :shock: Only problem is it's quite hissy.... put a tonebender in front of it to cure the problem 8...

Awesome! Yeah, it's really worth a build for anyone who likes octave circuits. Cuts through in a mix really well.

Has anyone seen and/or built this? I have built a few of them and it's a really useful circuit IMO.

FWIW, I purchased a xr2206 chip from a USA seller on eBay (for way too much money). It could very well be just coincidental, but this circuit sounds waaaaaaay better with the pricey xr2206 chip when compared with the three I purchased from tayda.

Thanks for that

Slick as usual, John. Would you be willing to share your PCB layout? That tilt option is awesome.

i just finished building one today and i dig it. here's the PCB layout that i drew up for it: Clusterfuzz Layout.png and here's the PCBs in a pdf file: http://johnkvintageguitars.homestead.com/Effects/Fuzz-ODs/Clusterfuzz/001-clusterfuzz_PCBs.pdf Awesome, John! I like your PCB layouts. They etch be...

Greetings, I am in the process of building RG Keen's Neutron circuit: http://www.geofex.com/PCB_layouts/Layouts/neutronpub.pdf I'm so confused by the toggle switch wiring! For some reason, the diagram is not clicking in my brain. :scratch: If anyone could point me in the direction of a gut shot show...

Just perfect!

Awesome! It always feels good to finally figure it out.

The guys over at TagboardFX have done a few vero layouts of this one:

Dino, your dog is really cute! My dog does the same head turn-y thing when we listen to Hendrix. All the phasing and panning really trips her out!
