Re: Fulltone - OCD [traced]

The schematic looks accurate, everything is hooked up the way I described. If anything needs changing let me know. aion mentioned some input buffer changes. If anybody knows anything let me know so I can add them to the pic. It's been awhile, but from memory it would have been C15 that was removed -...

Re: A Single Chip Phaser!

A general consensus states that device circuit diagrams are always drawn in the disengaged situation... I think that also applies to a MXR clone. I've been doing this for something like 13 years now and have never, not once, encountered this consensus... if anything, with regard to effects pedals, ...

Re: 5.6 Zener Diode replacement...

Look for the 1N5232B. It's an exact substitute with the same wattage rating. Mouser has them for 0.16 each.

Re: Looking for advice: Wiring the grounds on an isolated DC/DC converter [SOLVED]

Given all your info, I plan to wire this DC/DC converter's input ground and output common lead together, at the star ground point for the pedal. That's where I usually tie together all the various grounds including power, signal and chassis. That leaves the option of separating them for troubleshoo...

Re: Xotic - SL Drive

I didn't understand that decision. For 1590B, you have to use side-mounted jacks unless you use the 1590B2 or 1590BS, which are taller but much harder to find globally. A 1590B with side jacks takes up more horizontal room than a 125B with top jacks, even if you use low-profile plugs (and it's sign...

Nope, since 2018 everything has been 125B minimum.

Re: Maxon - PH-350 Rotary Phaser

That would be mine! I have the trace finished and am working on the board layout now. Hoping to have some progress over the holidays. There's nothing quite like the HTV vactrols, so I'm expecting the prototyping phase will take awhile in testing out substitutes. But it's one of my three major circui...

Re: Xotic - SL Drive

I did a reverse on my sl a couple of years ago. I see some differences. R19 (270 OHM) IN SERIES WITH THE H/MID CUT SWITCH AND C11. I measured C11 as 100nF. It's possible this was a revision of some sort, and the missing R19 and R20 in the numbering would certainly support this - but mine definitely...

Re: BJF - Honey Bee Overdrive degooped [traced]

I revisited the Honey Bee circuit recently for an updated PCB design and fell down the rabbit hole a bit. In studying the One Control version that was traced a few years ago, the Moody Sounds kit version designed by Bjorn, and the Blueberry bass variant, I started to get a feeling that we may have m...

Yep - a RAT with a couple of very bad component choices (but easily remedied... and sounds killer once you do). The channel switching selects between two drive knobs, which are voiced nearly the same, so it's more of a preset selector than anything. Schematic: stamps-drive-o-matic-trace-schematic.pn...

Re: Catalinbread - The Silver Kiss

Here you go! This is the Mk2 version, but seems to have been an early one because the RX and CX capacitors were wired offboard and it used a 2007 PCB (the same year the Mk1 came out). The PCB in the previous post looks like it says 2008 (though it's blurry and can't tell for sure) and it doesn't hav...

Amptweaker - Tight Drive

Amptweaker's first pedal design... lots of similarities to the Tight Metal/Tight Rock, but stripped down a bit. Less gain, no noise gate, a bit less tone shaping, no switches.

Re: Xotic EP-Booster [traced]

Here's the V2. The +3dB is kind of ridiculous... they added a series resistor in-line with the output that reduces the volume by 3dB, then added a switch to bypass it. So the +3dB setting is the same as the V1, and the new feature is that you can turn that setting off. Schematic: xotic-ep-booster-tr...

Thank you for your thoroughness and for sharing all those traces! Brilliant as usual.
