Summary I spent the past few months figuring out the dynamic sag portion of the Smallsound/Bigsound (SSBS) Fuck Overdrive and stuck it into "a Fairfield Circuitry Barbershop + SSBS Mini"-hybrid drive. The companion effect - an envelope-controlled voltage starve circuit - mimics a dying tube...

Video demonstration: Dying battery simulator - aka variable voltage regulator - aka (modded) JHS Volture. Overall circuit design by RG Keen. I also used Volos Projects' insight on the LM317 for additional assistance. PCB by me in Eagle. When the Volture first came out, I immediately knew it...

I used this schematic that I redid from FSB. Gray Bench Electronics also did a teardown of the pedal that showed a few variances like the Bass potentiometer (C500K -> C1M) and the Gain potentiometer (B100K dual gang -> A100K dual gang) and JFET selection. PCB was designed in Eagle. I did do a...

Very weird issue that I am having. Example Video: I incidentally discovered this while doing QA on my pedals - I get squealing when the following conditions occur: (1) Cord plugged in between amp and pedal. (2) Pedal is powered but effect not engaged. (3) No cord plugged into input jack...

Hello, Hell, I am working on a Harmonic Percolator clone. I want to add a bypass switch as seen here: Link. I have drawn up the following diagram. I will be using an SPDT ON/ON switch. Is my diagram correct in my thinking?

Good evening. Currently working on the Son of Ben (Benson Preamp) pedal. I am not getting sound when the pedal is engaged - however, the LED is turning. Furthermore, I have built an audio probe, and it appears the signal drops when I reach C6 in the schematic. To note: I used jumpers for...

I’m curious and I can’t find info on the subject.

Quick and fun build. I really love how this pedal sounds; high gain but full bodied. I play music in the vain of Brand New and Thrice, and I was super impressed with this pedal. The only modification I made is switching out the Cut pot (A100K) with a linear pot (B100K). I think it gave me more...

Where do I begin. I built this up on June 16 and it worked like 20 minutes but then the LED would stop oscillating and just stay on. So then I confirmed every component was correct then resoldered all my joints, which required me to also scrap the dual gang pot. Luckily I always buy 3-4 of the...

Currently building The Abyss. Two little metal spots, not touching the tracks. Cleaned board with isopropyl alcohol and metal spots still there. Wondering if this is a defective board or it’s merely cosmetic.
