I have a very stubborn 6-pin transformer that won't GTFO of my Neurocyton board. I already had a Neurocyton board that sounded like ass, so I went at it again with a new board, put in the MMBF JFETS in ascending order of IDSS, took special care to solder everything correctly. Aaaaand, being a...

Well looky here at what I made this evening with some sweet and massive mojo parts kindly gifted to me by @jwin615 that he acquired from a defunct police radio repair shop. Lots of crazy things like an N-D MOS (???), capacitors rolled in paper, and transistors I've never heard of. And very...

Mannnnn, I *really* productively struggled with this one. Tried implementing the mods in my old beloved o.g. deofol and ended up with questionable sound quality and an eventually non functional circuit. What was I going to do? Was I going to lay down and die? No. I tried to do it on a new...

Having tristesses modding the Windmill, so I needed a confidence booster, and built these circuits. [Edit: oops, forgot signal chain: Yamaha 735a (passive mode)>pedals>Sunn Sonaro with bright boost on, tone stack at 12, 2x15 cabinet, volume 2ish (I have neighbors with a baby).] I had built the...

Hey folks, It's been a frustrating week with pedal builds and mods. Finally measured all of my SMD J201s so I could implement the optimal OKKO Diablo/Deofol JFET cascade, and the crown jewel, the only 0.93 IDSS I have pinged off my chest and into the wilds of my basement when I was trying to...

I am trying to follow Chucks wisdom rebuilding the Deofol with properly sequenced J201s. But I've run out of through-hole, so now I have 20 little grains of effing rice to try to measure to find target IDSS and VP. I thought it would be as easy as making a viable test bed and plugging it in to...

For those of you with experience with this unit-- Gearing up to build one--do you feel that a blend would benefit the circuit a la Darkglass, or would it be kind of beside the point? I learned that it originated in my very own backyard--Atomic Music in Beltsville, MD. I've bought two guitars...

Having built the Aion TS50b, I was pretty dang underwhelmed with the circuit. Not a lot of punch, not a lot of dirt, kinda tepid and limp. Jesus Lizard? More like Buddha Newt. I realize some bass amps are like this. I rechecked the refdes and all and all, as well as crossreferenced to the...

So.... Finished this this evening complete with all boneyard mods, and it is phasering and doing what phasers should do, but Besides being a tad dark, It has MASSIVE gain (and no gain/volume knob). Like I have to turn down my guitar volume to 2 for unity. 10 is like quadruple gain with heavy...

For the sake of posterity and avoidance of future builder frustrations: Well, I did me a troubleshoot. Finished this duophase after being away and plugged it in with anticipation, but no. First, both LEDs were on, no sound except for strangled braps of distorted signal. Did I want to...

Built the Moonn "Cyberpunk Touch" and "Drone a Little Drone", but forgot to order pcb mount barrel jacks. So, I just soldered in some wires from a regular 9v enclosure jack to the PCB jack pads, ground to the round pad in front, and hot to the square pad in back. Didn't bother with the switch...

... any best practices? Since I have been on the mats in circuit dojo with sensei Bones, the importance of measuring jfets and IDSS and whatnot has become apparent. I have ye olde TC151 Amazon/Ebay made in China transistor tester. So how do I measure a grain of rice? Tack solder some...

My praise strat guitar dude coworker wanted a transparent overdrive, so I kicked him my old Cerulean build with the aion 18v breakout board. Since I rarely do decor, thought I'd put this out for posterity. The graphic is his custom and ridiculous request. Did some creative sanding, and...

Sorry, some have no gutshots since I don't have them. pPCB deflector aka Spirit Architecture: pPCB Twin Face aka Janus: pPCB Dragon's Breath (can't remember what I called it)

Holy geez. Most intense boxing ever. Crowded layout, double layers putting component ends on top of ICs and barely enough 3pdt threads to hang the nut, that big honking dual gang pot pushing all the off-board levels up, a huge 220 cap, and that's before I decided I wanted to try to make...

Here's my next PTP project, inspired by @GizzWizzKing 's build report of @Nostradoomus ' one-knob version of this @Chuck D. Bones Boneyard circuit, here. I reverted back to the OG layout because as much as I like one-knob jobs, I like switches and potentiometers and doodad parameter controls...

I was thinking of titling this one "Over the Hedges" as we have 6 non-PPCB circuits here. As per me, the circuits are built and functional, and I'm reporting on the circuits rather than my ability to execute the aesthetics. Sorry, ladies and germs! I have to get onto building my PTP circuits...

Redid JFETs according to Chuck's mods here, ended up with 2n5457 at 1.1 and 1.3 IDSS in Q2 and Q4, 1.7 in Q5; J201s at 0.46 each in Q1 and Q3. This gave me the best sound and also the best stability to address the ducking and swelling I was experiencing with the "Dynamic" pot set below 10:00...

Built it. Bypass, no signal. The classic. Checked to see if my 9v was correctly installed (that was the duh issue for my last troubleshoot). All good. Solder points at the jacks and switch. All good. Look at all of my joints. All good. Bust out the meter, measure the jack, and IC...

Given the extremely specific information on the 5457 specs in the Migfet build docs, I used my little box of Chinese Magic, the LCR-TC-1 Multi-function tester and no fewer than 11 through-hole 5457s. It gives the report as IDSS Id @Vg Id @Vg It's not super clear to me what these mean, I...
