yeah it's kinda neat - nice to see some (old/new) stuff out there. I love a good fuzz or distortion pedal as much as the next person but geez there's like 4 million of them out there!

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...

Thanks!! - didn't know about them. Reliable? I hear it's really hard to get genuine versions of these

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...

>>Tayda is very good for a whole lot. Is the "post service" (to USA) ie the "cheap" method still ok if you dont need it for a month or so? Or is it a gamble it ever shows up? All the other shipping costs are about $15 which for a big order is ok but for a few parts not worth it.

Never had a break IN the cable - always the ends etc. Of course I'm not on stage or setting up gigs.

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...

https://www.metcal.com/soldering-station/how-smartheat-technology-works-a-tutorial/ I just know it heats super fast - maintains temp and is very "light" in terms of the handpiece SmartHeat® heaters® heaters consist of two basic elements; a high-frequency alternating current (AC) power supply...

Metcal - the older bases can be found really cheap.

That may be significant. (I would highly doubt the 'mains' 120VAC as an issue). Unless you know what the power supplies do under load (power curve)- the "knock off" may be dropping off in voltage with the current draw. I just ran an experiment on some power supplies and bricks - the "Voltage"...

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...

there are a lot of small screw extractors (not sure what size you have) - they require a steady hand but do work. This one is more but supposedly made in USA so may be a bit better - cheaper ones may work too extractor cheaper one

I have the older original AD for my "home" use. I of course had to (in the spirit of pedal building) made a "case" for it out of an old LabView SCSI breakout box

100% agree. Any of the Analog Discovery - would work great. Two waveform generators, 2 channels isolated input scopes, digital - can measure noise, impedance, even frequency response sweeps. Super capable. python scripting, or in-app java scripting of the software. Check out the waveforms...

I think the L5 is +/-15VDC right? you would probably not want to go 9VDC -- 9 VAC -- (+/-15VDC) something like this just go from the 9VDC to (+/-15 VDC) Not sure if the mA is enough https://www.aliexpress.us/item/2251832630848518.html?gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US

I think I found the article: "Wow! A $227 gouge. (You couldn’t call it a “rip-off” because the phrase hadn’t been invented, but perhaps that is the only reason….) Obviously, this must be a very profitable circuit. Every competitor—and many customers—realized that the P2 must cost a rather small...

That P2 was really interesting. There's an article somewhere about it - the 3d arrangement had capacitance coupling (I believe unintentionally)- not on the schematic - and when people tried duplicating the circuit they couldn;t get it to work. It relied on the physical arrangement of parts! I...

I have some of the Philbrick stuff.... cool museum pieces https://www.electronicdesign.com/technologies/components/article/21802868/an-amateurs-view-on-the-p2-part-1 Sporting input bias currents in the picoampere range (1x10-12), the P2 cost $220, which was 1/8 to 1/2 (my source for this...

I love that - I've seen some commercial stuff but am surprised there's not more out there.

Had not seen that these new JM pickus are out - interesting. Quite a bit lower 7.3k than the old J Mascis Squier 8k versions.
