My client (my one and only client!) requested a phaser. He wasn't sure between a Boss PH-1R or EHX Small Stone. But, as always, the community here was extremely helpful. We ended up going with the Boss PH-1R clone via the AionFX Emerald Resonant Phaser project. It's a fairly densely-packed...

Duty Calls.

Just to hopefully add to the conversation, there are some pedals that use a simple capacitance multiplier for further filtering. I don't know if all Boss pedals do this, but many of the schematics I've looked at include one, e.g. OD-3. The Chauffeur Drive has an interesting power supply, which...

To be pedantic, there will be some current-dependent voltage drop due to RDSon. But as in temol's examples above, having a series resistor is useful for creating the low-pass RC filter with the bypass cap. Another alternate solution for reverse-polarity protection is a diode between Vin and...

There's a few folks around here who do "stacked PCB" builds, with a custom bypass board that mates to PCB-mounted input/output jacks. The actual effect circuit is directly below the bypass PCB. So in bypass mode, the effective wire length is roughly the width of the pedal. But I agree...

@Stickman393 - thanks, that's really useful info! You didn't mention it, but I'm guessing that over time, wear and tear on the contacts (via arcing, or maybe even just friction) will cause the bounce behavior to change somewhat too? Now I've gone down a SPST momentary rabbit hole. I think I'm...

There is plenty of open-source code for microcontrollers. Shamelessly linking my own code, and the credits and links section of my README has links to other open-source implementations. I'd argue the only really tricky part of writing simple on-off mcu code is the debouncing, and that's a...

Random thoughts… I prefer soft-touch switches, either for use with a relay bypass system, or even a Boss style electrical switching scheme. But that’s my personal preference. To those who prefer mechanical 3PDT I say cool! (Unless they don’t post gut shots of their builds, that’s not cool! 😎)...

I recently commented on Sunnyscopa film-free laser jet waterslide decals in this thread: Waterslide paper suggestion. There it was mentioned that there is new/different glue that now comes with these waterslide decals, and that it's process is different than the old glue/aka transfer agent...

This is my build of the Aion Cepheus Amp Overdrive based on the Cornish CC-1. Aion's description of this pedal and Cornish pedals in general is good; he goes into even more detail in the tracing journal. The same board can be used to build the higher-gain GC-1; Aion's build docs have the BOMs...

Just wanted to post a follow-up. I've been using this pedal since I built it, and it's pretty much exactly what I wanted: a Spark Booster better tuned to my needs. Chuck managed to read my mind when he tuned and tweaked this circuit! Comparing the modified Dark Esbat to my Cast Iron, the Cast...

Because of my infatuation with the Animals Diamond Peak mod, which is a similar circuit that also calls for low-gain silicon transistors, I've got some notes on some you might be able to find: 2N4123 - Tayda - HFE 84-106, most at 94 MPSA42 - Tayda - HFE 85-108, most 85 or 95 2N2369A (plastic...

Thanks guys! I pointed him to this thread, hoping to get a little more direction, and he said: He also said he'll watch some demos. But based on his comments, and the feedback here, it sounds like the PH-1R is probably the better fit.

I have someone who wants me to build a phaser, either a clone of the EHX Small Stone, or the Boss PH-1R. Looks like Aion has boards for both of these, the Sunstone OTA Phaser and the Emerald Resonant Phaser, respectively. I haven't even played a phaser, let alone built one, in decades. The...

I assume you're referring to this discussion. Note that this Dark Esbat CDB mod shown here uses a different switching system: it uses a CD4053 for the actual circuit switching - it's an electrical switch, as opposed to a relay/mechanical switch we discussed in the other thread. Sure...

I finally got around to making a PCB for this! Build report here: Chuck D Bones Modded Dark Esbat / Ember Boost. Spoiler: it's exactly what I hoped it would be, a TCE Spark Booster with the mode/mids knob better tuned for my purposes. I have a few extra PCBs for anyone who wants one. I can...

A few years ago, I build the PedalPCB Ember Boost, which is based on the TC Electronic Spark Booster. This is marketed as boost, which it certainly is, but the "fat" and "mid" modes also make it useful as a light overdrive; the Baxandall tone stack gives it a fairly flexible EQ. The core...

100% this. Awesome badass work and build!

Great build, thanks for sharing!

@Eugene_M - See here for an answer. (Thanks @jwin615 for the mention, otherwise I wouldn't have seen this.)
