looking for some encoder knobs - ideally aluminum, black, but have to be without "indicator" - D shaft would be perfect but I can adapt to 1/4 or 6mm these seem to be surprisingly HARD to find. ideally something like this but no top or side indicator...

I inherited a bunch of these 2N1304 - tried to measure them as best I could - see pics. Worth anything to try to sell on ebay or somewhere or not worth the hassle? Made a few fuzzes with the ones 2N1306/7 that were higher gain now theses are just gathering dust. Also have a bunch of 1N994...

I figure you all might have some experience or know someone.... Anyone know a source for part number and or parts for Boss pedals? Specifically I have a RV-500 with a bent TIME encoder and need to replace it. Not worth sending it in ext for a fix. It really looks like this at Tayda is very...

Sorry if a bit of off topic - but FX loops are a big thing with using my pedals I build. Was thinking of messing around with one of my old SS amps - good old Peavey Blazer. Was wondering if anyone would be able to give me advice on where I could add an FX loop? I looked at some of the other...

I want to make some custom power cable (9V) lengths. The only thing I can find are the super cheapo junk ones. Anyone have good source for the plug types like this? They shouldn't cost $3-8 for a connector. THESE NOT these

So I've been messing around measuring the effects of load on various 9V power supplies I have. Most are switching mode power supplies but I've looked at the old school transformer ones too. Looking at the voltage with a scope is interesting to see the switching artifacts. The BEST by far is...

Anyone use the tayda momentary footswitches? They also carry the Daier version - but Daier (sometimes) has the smaller actuator 8.5mm dia vs this 10mm. Quality? Smoothness? I see Love My Switches has some that look pretty similar. Anyone use the Tayda switches? Interesting they say it has...

Anyone know a place I can get low profile momentary switches? Only need a ON-(OFF) ie normally CLOSED momentary since it for a BOSS pedal CTRL1 and CTRL2 input. I don't want a "tall" enclosure. The "XWING" types would work switch-wise but Im looking for a little shorter. Something that would...

Interesting - can't be too difficult a circuit. Combination mini reverb tank and some optical sensors etc https://gamechangeraudio.com/shop/light-pedal/ The LIGHT Pedal is the world’s first analog optical spring reverb system that uses infrared optical sensors. This system is used to harvest...

I know not "pedal relate" but there's a lot of experience here and was wondering if you could help a fella out... Have an old Peavey SS amp with a TDA2040 - TDA2040s, from what I hears, are widely counterfeit :( Anyone know of a reliable source for a TDA2040? Cant find it from my normal parts...

Anyone diy a cable tester? I've built a ton of guitar cables, RCA cables - it's always a PITA holding the cable and multi-meter leads to check out my wiring. So I had some time and parts sitting around and came up with this. Im sure Mr PedalPCB could come up with a vastly better pcb (hint...

So I've been messing around with measuring dedicated power supplies for various pedals I have, and with some multi-outlet "pedalboard power supplies" (bricks) and have some question about what "range" of voltage supply would be acceptable. This all assumes current supply is adequate etc. Now...

I think I posted some of this before - but I'm still confused about "output" stages in pedals. I assume most pedals are "designed" to work with guitar inputs on amps. So the amp typically has a high impedance 1meg etc right? But if you want to plug a pedal into a "line level" (either +4dBu...

Anyone have one of these boxes? Would love to see inside or a schematic. Could make a cool pedal - hint hint....

So a harmonic tremolo has a High Pass and Low Pass section. Each with a LDR (not sown in circuit). Can you get a "normal" tremolo sound by only using one of the paths and opening up the filter? Something like below where you switch C7 and C5 so they are either "off" (as shown = normal...

Go the bug for a tremolo... I don't have a harmonic trem, does the Pendulum sound anything like the Supro?

Not too much smt experience - working on a driver board for some RD. First Question I have a 80 pin BGA array package that I *have* to use, with all other thru hole components. Somebody mentioned I need a "tooling rail". ? Cant figure out what that means. Is that just a boarder around the...

Anyone tried the "toner transfer" method for pedal artwork? Looking for recommendations and success stores on what brand of paper etc My -pedals have a thin (0.030") aluminum 2.1"x2.1" plate where all the graphics are - so Im not heating a large area and I would think this method would have at...

Are the Tayda standard 16mm same as or as good as the Alpha? Anyone have issues with either? Just curious - they look the same - likely from the same factory.

So I'm doing a surface mount board for the first time. I've done a few dozen though hole projects, etc. It's going to require a different strategy I guess! In my through hole designs it sure is nice to have the option of FRONT or BACK (2 sided board) due to the nature of "through holes"...
