You can run a passive Bax tone stack with high input impedance, you just lose a good amount of volume and have to play with values a bit to bring the HF response back up. So you could experiment with putting it in without a buffer and see if you can make up the desired volume with a single...

Jumping on to say thank you to everyone who contributed to this thread, and wishing I'd read it last year. I've been away from the site a while because I decided to design a pedal, start a company and ruin my fun hobby by trying to monetize it. I launched the website and payed to play with a few...

Thanks! I've been contemplating PCBA daughterboards but am intimidated by the process and have failed to research on my own.

Sorry for the late reply. I can't remember where they came from but I'm guessing my local electronics store. The whole place is a collection of old stock from the 60's-90's just because they haven't needed to restock maybe ever? I never see anyone else there, I don't know how they still exist.

Scabbard drill template The hole for the led is sized at 6mm for one of these bezels. Tayda has the mounting hole sizes listed for the other bezels, so if you want a different one or a bare led, just add 0.2mm to the size of the mounting hole.

Just finished reading the 2nd book after getting through the first a few months ago. I didn't/still don't know much of how things work and thought both books were pretty great. I have a much better understanding now despite largely ignoring the more complicated math included in the text because...

I also signed up for a month, I like it so far. There aren't a ton of component choices, at least for what I've been using - jfets, bjts, and diodes - but you can import spice models in text format and save them. From a quick look at the menu, all the schematic export options are graphic...

I'm also interested. I would grudgingly shell out some dough for something more intuitive than LTspice that can do all of the above.

Thanks, it's possible to get a clean reverb with the clean blend mod, but it also really limits the wet mix of the reverb. The other option is to roll back the guitar volume, or otherwise limit the input signal to the beholder and turn down the fuzz control, then you can also get a clean belton...

Keeping them in the current position has better isolation from the power supply anyway, probably the best spot without a major layout change, don't mind me, keep up the good work.

I don't know how I missed this thread, great idea and execution. I'm a little worried about the tubes mounted horizontally next to the pot and switch wiring, but it's probably fine and not worth it to mess with different pin headers to get them standing upright. Now I want to build one in a slim...

Thanks, that's what I do with 3mm LEDs, but your picture fooled me into thinking it was a flush lens, it looks much nicer with 5mm, I'll have to try that.

I really like that led bezel/lens, are you willing to share where you got it? It just looks so clean and appears to sit flush or close enough.

I used 1N34A's for the D6-8, but you can use any diode you like. The spot is meant for a germanium diode, but if you don't have any or want to pay inflated prices or wait for one from Eastern Europe, a schottky diode like a BAT41 will make a reasonable substitute. The muff circuit has two...

Thanks! It's a jfet preamp into a Si FF output stage using low gain soviet transistors with a foot-switchable dirty boost in front. Toggles are for the coupling cap into the FF stage and a low pass on the output. Waiting on enclosures to arrive from Tayda them I'm going to send some out to a...

Still not a masterpiece, but it's getting less chaotic, great inspiration on this thread, and of course from the master @Robert

This is my second build of the Sputnik II, the first was the DEFX Laika Fuzz V2, which was one of my favorite fuzzes, but in a visually displeasing horizontal 1590BB layout with all the knobs straight across the top. So, I saw @PedalBuilder 's post of his Polaris Fuzz and ordered a board from...

All I have left are the actual PCBs. I was in the habit of overwriting the layouts when I updated them. I'm saving independent versions now so I can look back at what I did. But yes, it was very much not a scientific test, lots of variables.

My newb 2 cents is that I had two versions of a board made recently, one with the best I could do, but still not optimally placed 9V routed trace with ground pours on both sides, and another with a 9V pour on the component side and ground pour on the reverse and then nicer/shorter routing for...

I've used them in DEFX Spaceman projects, all of which are pretty low noise, but I can't say how much the ferrite beads are contributing. I never thought to check Tayda, just got a roll from a seller on ebay like these, probably the same thing at Tayda. Edit just found these at digikey for 18...
