    What would I do with a germanium PNP with an hFE of 18??

    I forgot why I acquired these. Are they useful for anything with an hFE this low? (18 hFE, PNP germanium.)

    Would Topographer dist. sound better with the proper 42TL218? Or any 10k:10k wind ratio will do (like the 42TM018?)

    Whoops, I bought the 42TM018 for my Topographer, and when I went to build it discovered the BOM calls for the smaller footprint 42TL218. Both have the same winding ratio (10k to 10k ratio from primary to secondary.) So I'm sure it will work, but will it sound as good? What I know: Transformer...

    Snow White Ottawa, yet another auto wah, tasty and versatile. PPCB Poison Apple

    I've built 6 other auto-wahs, but I heard such good things about the Mad Prof. version, I had to give it a try. Why not? I'm apparently in the build-every-autowah club now. I like the ability to turn down the resonance to avoid being scalped by the squawk. You could use this in subtle mode...

    Another Wise Sheep from Sheepylove via Michael W

    Thank you Michael and Sheepy for making this available to the masses. I was excited to give this a go, because I've never built a “Blues Breaker” style pedal. Since I've built every other classic circuit (TS, Rat, Muff, etc,) I had to give it a try. Easy build. Slightly higher gain than many...

    SOLVED Is it possible to use a VFE switching soft relay bypass PCB with a regular Madbean PCB?

    I'm using a VFE bypass board (by Madbean) with Madbean's Pepper Spray (Harmonic Perc.) Audio switching works perfectly, but I can't figure out how to wire the LED. If I can't make it work, I'll just skip the LED, but it would be nice to solve this.

    LED Ring Stompswitches, anyone sell *just the lens?*

    I love these LED ring stompswitches. But I always chuck the switch. Does anyone know if you can buy just the translucent ring diffuser? Or buy them without the switch.

    SOLVED Intermittent (Intelligent) Bypass Board, a finger touch turns it on, I need ideas

    I cannot locate the short on this bypass board. I've reflowed all the wires and both sockets (IC and relay.) Resoldered the 2n3904 switch transistor, etc. Is there some edge case where the transistor won't switch? The reason I ask is because I'm using Intelligent Relay Bypass on everything...

    The Thing (Dynamorph from DeadEndFX) LEDs are always lit (and not in a good way.)

    I very carefully built "The Thing" from DeadEndFX, and the moment I plug in 9v, the LEDs light up. They're supposed to pulse with the guitar attack—adjustable with the trimpot. And they do at certain settings, but they never go fully dim. The 3 on the left are brighter than the 3 on the right...

    Wiring a PedalPCB breakout board to a non-PedalPCB effect?

    Can anyone confirm this is correct before I dive in with melted lead? There's a separate pad for 9v in to the Soy Sauce Subharmonizer (not pictured.)

    What's a good clean (no fuzz) octave down for bass?

    I've just been hipped to the notion of OCTAVE DOWN for bass. Problem is, all my octave machines add dirt. Is there anything clean for bass that isn't digital (i.e is buildable?)

    Awful Falafel. I just had to try the chicken and waffles even though it's a weird combination.

    Love it. Simple build. One very unique overdrive to add to the arsenal of recording options. I never heard a YouTube video of the Hotcake that sounded good. But I built one anyway because I knew it was different and I had to hear it in person to make up my mind. It's way more interesting than...

    SOLVED My Waffle wants three 100k resistors, is this a purposeful revision?

    Hi friends, building an Awful Waffle here. I'm seeing an extra 100k that's not in the BOM. I'm assuming this is just a recent addition and it's OK to build to the silkscreen. But since it hasn't been mentioned before, I figured I'd bring it up. Looks like the output pad still goes directly to...

    Rocker '83; it's a keeper.

    Five stars. Straightforward build—and contrary to popular belief, no build docs were required. ;) Colombo is batting 2 for 2; this and the Golden Falk were greater than I expected. Lots of surprise harmonic nuances in both. I'm glad this turned out so well because I like to save my precious...

    Mad Professor Deep Blue Delay (MadBean Sea Urchin PCB Layout)

    Here's one I built before lockdown. Pink LED, white washer, toner transfer graphics with epoxy resin on top for protection. Knobs leftover from an ancient Paia kit. Home-etched board using a Madbean layout. Stompswitch PCB from 1776Effects. These days I put labels on all my boxes...

    Is the C-Buffer “always on?”

    This might be a dumb question, but is the C-Buffer always buffing? Even when the effect is bypassed? My guitarist feels like he's missing out on the buffer trend. Can I build him something at the front of his chain (like a compressor) with a C-buffer that will help even when the compressor is...

    I'm out of 1n5817 reverse polarity diodes, can I use another schottky?

    Hi folks, I've got some Intelligent Relay Bypass Modules to build and discovered I ran out of 1n5817s. I have a bunch of other Schottky diodes with values ranging from 4v to 40v Can I use any of those assuming they're rated for over 9v? Or should I hold my horses and order the correct part?

    Anyone ever reamed out a 6mm aluminium knob for a 6.35mm shaft? Good idea or not??

    I wanna order these groovy ass knobs for my next envelope filter, but I can't find a 6mm shaft pot in reverse log 100k (not even from Tayda.) I have a harbor freight drill press and below-average skills with it. Can I ream these out? Is it worth trying? Or am I gonna end up with a case of...

    DEMO Did someone say Nun More Black? It's a Disarray distortion (sb an Obsidius.)

    Here's my entry into the “none more black” sweepstakes. I'm disappointed in myself because Diynot's NMB was an Obsidius, and Mbenbranch's NMB was also an Obsidius! I should've built a black Obsidius! But here we are: mine is merely a Disarray. I already ordered the enclosure before I knew about...

    A couple dumb questions about the Corduroy fuzz (input transistor swap?)

    I've always read that you can sub MPSA18 for the 2N5089, but that has an hFE of around 8-900 vs. 6-700 for the 2N5089. (I don't have any 2N5089, but I have a bunch o' MPSA18's.) If I used the MPSA18 (800hFE), would that change anything for the worse? Or should I just add some 2N5089's to my...
