    STFU Optical Noise Gate

    Another question - is the anode of the vactrol really connected to ground? Several of the DOD 230 gates have the anode tied to pin 7 w/ 10k and cathode to ground, which I would think is normal. Unless we're relying on the inverting input driving negative, which the supply isn't capable of.

    DEMO Figment Preamp (Acorn MIGFET 50P)

    Exactly - I guessed a 30-50% reduction would help, a random 11k resistor was the closest I had extra of that would accomplish the drop while keeping similar impedance.

    DEMO Figment Preamp (Acorn MIGFET 50P)

    That was just my implementation of getting a more useful sweep given the parts I had on hand. Felt like a more intuitive sweep with the log taper, and I also broke the linear taper when lifting a leg. The resistor is the main component to add, limiting the overall output. I've used internal...

    EEPROM Builder…I’m sorry if this is dumb…

    No comment here - I used the arachnid and spatialist PCBs as-is which work great

    Select what you want already programmed to it. It'll have a custom part number when it shows up reflecting your selection. I've done 2, super easy process

    Valhalla Distortion issues

    I built the aionfx version and it squeals without a buffer pedal before it, or something like an OD.

    Electro vibe mini - with mods!

    Given the lack of published refdes DWGs, where is "R4 - 2M2 - Unity vol mod"? Your images do not jive with this google cached image of R4.

    TPA3118 60W Power Amp Module

    Confirmed all 4 feedback resistors match, as well as the feedback loop caps, and their connections to ground. A standard PAF output humbucker will give clean tones up until about noon, after that it starts clipping. I messed with it and changed R1 to a 82K and B250K pot in series, R9 to a...

    TPA3118 60W Power Amp Module

    Update, tried another 3118 module., one of the ones with "35v" caps and no mute pad. No problems. It gets a bit of mild clipping when running at very high volumes through my 16ohm speaker. Not really sure what was going on there. Maybe an input gain knob would help to limit some high volume...

    TPA3118 60W Power Amp Module

    Testing with just a guitar on the input. It's clean until about 0.5/10 on the TMB volume knob, after that it gets louder and more distorted. I did the perf board first, then breadboard to debug it. Both behave the same way with or without the TPA3118 board attached. Using my audio probe with...

    TPA3118 60W Power Amp Module

    I'm running the circuit from post #161 - the TMB. Is it expected that each half of the opamp clips and introduces significant distortion? Powering mine with 23V+. 1in+ and 2in+ are both at 1/2VCC. I've soldered onto perfboard and breadboarded it. From most of what I understand is that this...

    Lead Solder Overdrive

    I too needed careful positioning of the wires to prevent oscillation. Even going as far as rotating the jacks helped let the gain knob ride higher before squeal. I built two boards at the same time, one was more subject to having issues than the other. Put shielded wire for in/out and the...

    DEMO Figment Preamp (Acorn MIGFET 50P)

    That sounds amazing, I need to find something that does the same magic as the super tube screamer, my sd-1 gets the figment close. I ended up swapping the b10k master for an a10k with a 11k in series after the 2.2uf of the output. This gives excellent volume control.

    DEMO Figment Preamp (Acorn MIGFET 50P)

    Any thoughts on changes to make the master/volume knobs more useful? Mine is also only tame with them below 9o'clock before things get out of hand.

    Intelligent Relay Channel Switching Bypass Question

    Amazing! Thanks for your input. I'm short a few parts (relays) , but will definitely try one of these methods in the future.
