    Special K Ge vs Si

    I was thinking 1S1588 were much lower than 1N4148, just spreading misinformation in an area already full of it, oops. Ignore my post, get the Soviet ones like @PedalBuilder said.

    Special K Ge vs Si

    1S1588 diodes have a lower Vf than some other silicon diodes but still higher than a D9k or a shotkky, sort of a middle ground. I'm not totally sure but I think they still have a steep curve like most other silicon diodes as well, so they should give different textures in addition to different...

    Bring out yer Diptrace

    Feeling real dumb, -9V on one side and +9V on the other wouldn't be a 9V power supply. I wasn't thinking, just trying to fit things from the supply pins category of the rullywow library into the schematic for the pads I knew I needed for connections on the board. Many thanks, I also forgot I had...

    Bring out yer Diptrace

    Thanks for all the tips, I definitely need to rework the power supply section. The clipping LEDs occasionally pulse while I'm playing, so I assume they're working? They're just there to prevent hard clipping from the jfets. -9V(T) is the pad for the negative connection from the DC jack, I wasn't...

    Steggo Builds Another Vintage Fuzz - PedalPCB Octa Mayer

    Great looking build and art! Archaeopteryx was my favorite dinosaur as a kid when I wanted to be a paleontologist, but then I did drugs and worked in kitchens instead, so thanks for the reminder of my amazing life choices.

    Bring out yer Diptrace

    I just got diptrace and finished my first "original" design, it's cobbled together from online schematics that I've fooled around with on the breadboard for the last 2 weeks, anyway, please point out any glaring errors you see in the schematic. I ran the electrical rule check and corrected the...

    Special K D9K vs 1N34A

    I got 60 D9k's a while ago and there's a decent variety of forward voltage drops. They were pretty cheap from Ukraine or Bulgaria, so they're my default Ge diode because I can usually find one in the same range as whatever a circuit calls for, so I'd say unless there's a Vf specified it probably...

    US customs are assholes, if Portugal is the same then my condolences to you.

    PPCB Arkaim and DEFX Zuperbee

    It's the only board I know of. They also make a board of the TAFM, which I like better on bass, and slightly better on guitar, but this one is still cool.

    I had a rough day yesterday.

    I got the fx888d a couple of years ago when my ancient hakko died, it's been great for me. Sorry about the crap day, reminds me of one of my favorite book quotes: "Truly, life is the misery we endure between disappointments"

    What's your current headache?

    I left Chicago 2 years ago but I bet my apartment from 3 moves ago is still unrented. It's huge and cheap and heat is included, but one of the rooms is mostly mold and I moved out when the ceiling in one of the bedrooms caved in and they wouldn't fix it. DM if you want the address, but the...

    What are you currently reading?

    Finished Use of Weapons by Ian M. Banks last night and started The State of the Art. I've just been reading his Culture series in publication order, though it doesn't really seem to matter, and have be pleasantly surprised at the ideas, plot and quality of writing.

    What’s on *YOUR* workbench?

    First thing I've built from a schematic, and first project on a breadboard, and it actually works, doesn't sound great yet, but it works. Hybrid Si/Ge Meathead Dark. I think I just need to swap some bias resistors/trimmers and find good values and it'll be pretty good. Using low/mid gain 2n2369...

    PPCB Arkaim and DEFX Zuperbee

    Arkaim first, very pleasant build. Low parts count, beautiful pcb layout, drill template was spot on for UV printing and drilling my own holes. I don't love the sound on guitar, most high gain metal fuzz sounds kind of cheesy to me, but on bass it's tons of fun and seems like you could find a...

    Adding indicator leds

    Probably the easiest thing to do for a power indicator is to have an led on the breadboard, long leg to the 9v supply and short leg to ground, use a current limiting resistor in series with the long leg if you don't want it to be blindingly bright. I'm stumped for wiring a bypass indicator on...

    What "brand" of wire are you using? consolidated wire- pros/cons

    I've been using solid core on all electronic projects other than cables for a long time, but it can be a pain for cramped off board wiring. I currently have a bunch of remington industries 20awg(also available in 22awg) that I've been happy with, my only gripe is that it's pvc insulation, so a...

    Glass Capacitors?

    A long time ago I bought 200m of 1940's speaker wire from the West German Telefunken factory, it was supposed to have some mojo and I was impressed by the provenance, but mostly it was just a nice price for cotton sleeved pairs of rubber insulated tinned copper wire. I still have a bunch and use...

    Glass Capacitors?

    No personal experience, but Wikipedia says the advantage of glass capacitors is that they can be made to be virtually non-microphonic, with the downside being cost. They seem to fit the canon of mojo parts in the sense that they may offer better or worse performance on paper and likely have no...

    Aion Spectron(Lovetone Meatball)

    Thanks, it is fun before gain. I like to do light fuzz into the meatball with color and intensity turned down and then run that into the TAFM clone which is a fuzz with a clean blend. Maybe one day I'll record something with all my fancy music and recording equipment. Edit: highly unlikely...

    SOLVED Ritual fuzz no output signal

    Easy test for that one is to use a cable and see if there's less hiss, but I bet wireless introduces more noise than a cable.
