when i first discovered this board in the pedalpcb shop, it came to me at just the right time.. before i had even tried an ST-9 circuit (my favourite), at the time (‘22) i was all about the 808 circuit (OD808/TS808). I had this idea where I really wanted to do a discrete opamp version, and was...

in what way? does this cause noise or something? always wondered what the point of series resistors in power supply inputs were for. e.g. opamp muff:

already built one 3 years ago lol jk but yeah idk, a mic pre built into a delay? looks like another solution looking for a problem very few would have.

well @Feral Feline you are an odd fellow, but I must say, you steam a good ham

got one of these? if yes, assemble this, and drop your lil guys into D1 & D2. \

OP07

it doesn't matter. parts list doesn't specify for either B or C. BC560 is PNP. if you want to sub it, it needs to be PNP. i used a BC557 in my build. no issues.

i'd say these will work fine. FYI - your attachments are hidden/private.

or, breadboard the circuit first, pick your favourites, THEN solder it to a board. sockets are hideous.

well, look at the legs. gotta be careful when bending, cos all of the force that gets put on those legs goes into that piece of brown phenolic plastic, so it is subject to quite a bit of stress. learned the hard way one day when i was trying to bend all 3 at once by prying against the bench...

https://www.deadendfx.com/product/hooke this one uses a TDA7052B to drive a mini accutronics tank. there's a veroboard layout available for the above project (spaceman orion/hooke). fits in a 1590J. i reckon it sounds pretty good. (build thread w/ demos)

i ended up going with values from the fuzzdog 'stable version' schematic. (those x2 100n caps will be replaced with some slim 220nf i got from mouser recently) started a board, got distracted, and haven't finished it yet. (maybe that was intentional, cos the tone cap position is still vacant...)

do you mean collector or emitter? apologies, the references get a bit confusing when the transistor is flipped. for context, i’ve currently got your schematic breadboarded with some MP11A NPN Ge. with the collectors hooked up to resistors (390R) to ground, im seeing about 0.03V at Q2C and Q3C...

cheers guys, it’s not too bad making one when you can just use the metal lid as a template. i didn’t get it perfect, little bit wonky but im just glad the holes lined up

ayy thanks! 🤟🏻

i’m sure anyone that’s had a browse of the range at effectslayouts has seen this nifty little board. i only bought it cos i thought it looked cool, and it is cool, but i was never really sure if or when i was going to build it. but recently i’ve been enjoying building with 1590B, and getting...

hell yeah brutha 💪 built one of these last year, on vero. will go full on tight metal if you try boosting it with an 808/SD-1. i was also a little bit shocked at how much gain is available. which diodes did you sub for the Ge? (i also used 4148s in place of 51E) only really noticed a...

if you're willing to try building with something different... https://tagboardeffects.blogspot.com/2013/04/1-knob-fuzz-bonanza.html https://tagboardeffects.blogspot.com/2013/01/electro-harmonix-lpb1-with-trimmer.html

yeah i saw that one, was kinda shocked to see someone had actually used my layout. probably wouldn’t be that hard for someone (smarter than me) to adjust that schematic for a pedal application.
