    Where's thr Cornerstone Gladio's at?

    What happened to the Gladio post? There were some gutshots in that thread but the whole thread is gone now?

    Nope. Northern FX.

    Low gain fuzzes

    I recently acquired a Tarpit by Greer. It's a take on the v4/5 op-amp muff, but I found it to be great with low gain settings. The tone pot it seems has a bigger range than most muffs. It can do gated/broken sounds with the gain on 0 and all the way to Billy Corganish at max gain. I set the gain...

    You might find that in a certain companies pedals. Won't name it, but they're FX build somewhere NORTHERN.

    Shrapnel missing 9v zener?

    Edited my previous post (bout the 47k, misread the photo) I will check again tonight with the schematic, thnx!

    Shrapnel missing 9v zener?

    Note: I modified mine slightly with a 3.3k upon 4.7k for a bit more gain/ a 150nf and 220nf metal film cap instead of the tantalum and a silver mica 47pf instead of the original 51pf ceramic. The 100k in my pic was original though. I drew the trace of the zener too.

    Shrapnel missing 9v zener?

    I checked mine, ser.nr: gun0897 and the "SHO" zener does make a ground connection. It's a "V1" big enclosure but the pcb states "V2.1" so that leads me to believe there are some previous revisions done. I tried to trace the "missing" zener and found it to be in a loop with the 100R resistor...

    Shrapnel missing 9v zener?

    Just finished my shrapnel pcb and testing it. Sounds awesome! But comparing it with my original thorpy gunshot circuitboard I found out the thorpy has an additional (2nd) 9v zener in the circuit that the shrapnel hasn't got. They sound similar but that has me wondering how essential, and what...

    Clone comparison

    In the past year I've build a pedalpcb Pyrocumulus, Mach1, Duocast and expecting the Shrapnel next week. Still want the Southern belle too, but not available yet at musikding. (I'm in the Netherlands so Klaus is my go to for Pedalpcb products) Here's the thing: I had a thorpy Fallout Cloud...

    Duocast noob question

    Got the 35v caps. This is a great pedal and I seem to dig it most at 24v as a boost on low mode. It brings a presence to my sound with a bit of grit that's usable with clean or overdrive sound. Still experimenting with the gain trimmers and my stash of telefunken/rca/Phillips and mullard...

    Duocast noob question

    Thnx, i think I'll just leave out the 1054 ic out first then, got no more 35v or 50v lying around but i really want to finish it and hear it. I figure when switching with no voltage doubler present in the circuit, but the 5817 diodes all present might give some interesting results as well 😅

    Duocast noob question

    How essential is it to have all electrolytic caps in the Duocast rated at 35+ volts? Are there any that don't require that rating? Especially the 330uf. And is it possible to modify the charge pump to 18v? By removal of a 5817 ? Noob.. i know..

    Shrapnel Overdrive Mockup Pedal

    Build a bufferless tubescreamer with a zvex SHO in 1 box and run them in series to a shared master volume. That's what a Gunshot basically is 😉

    Bc 107b philips

    Thnx! I got a 24v supply max, how fast will it discharge with the 10k?

    Bc 107b philips

    I only measured capacitance which read well over 200uf, which is quite a drift. They are rated 63v.

    Bc 107b philips

    I did! 2 of the 100uf read way over 200uf! ? The 10uf were fine though, even as the tropical fish caps, these were pretty consistent in their values. Also a few polystyrene 1nf in the bag, they measured: ... well.. 1nf precise! I'm really impressed by these old philips stuff, and thats not only...

    Bc 107b philips

    just found a little NOS treasure with a bunch of philips bc107b's and mustard/tropical fish caps/radial Electrolytes. Need some inspiration and suggestions for something to build with them.

    "Express Lane" Pedals

    Emerson's EM drive. A whopping 5 parts on the board. 2 resitors, single transistor, 2 caps.

    Soothing frequencies

    Thnx for your replies! Tweaking pedals and amps is a thing a lot of people spent time with, and do too much sometimes I noticed. And that was what started to intrigue me. Is there a "secret" frequency setting regarding your amp and pedals? Or pedals that sit exactly right and operate in that...
