around the same time that I had the idea of doing the discrete opamp SD-1 with the Wilhelm Scream PCB, i also pondered similarly about the ST-9 and thought what if, instead of having an ST-9 based around the TS-808/TS-9, why not build one based around Boss SD-1 values instead? initial...

https://amzn.asia/d/5CU5jXo this is what i’ve been using for all my demos

alright, here it is. finished a HM-2 build on the breadboard this arvo. it's gnarly. gotta do a demo soon. so tonight i plotted out a russian muff on the free space left (minus tone circuit & q4), and got it running into the HM-2 EQ. but it’s 1:45am so i can’t properly test or hear it yet, but...

so sorry to hear about the passing of your wife. i would absolutely love to help with this, and finish these off. but unfortunately i am too far away in madmaxland for this to be feasible 🫤 and then there's the risk of it going missing in the post

the key to all of this is to DRY FIT everything (and i mean everything) to ensure fitments etc. before applying solder to anything. (here's a pic where i've checked the fitment of the two boards together with the header pins/sockets already mated together, which is how they should be when you...

ay great work! 🤟 looks excellent. many thanks for taking one for the team and warning us about the jack fitment. (yet to build mine 😅)

despite claims that the amptweaker tight metal is meant to emulate a 5150, the aionfx version, "ember metal distortion', i built was quite a disappointment. there's definitely better distortions out there. e.g. the brown betty i built was way more fun. [although i reckon the 6 knob version...

cheers! none of this is really all that serious, (my preferred rig/method is a drive boosted high gain tube amp channel) it's all just a bit of fun and experimentation with the circuit that left a huge impression on me from my youth, by making otherwise awful cheap solid state amps fun and...

i was considering posting this in the modifications sub-section but im not sure that a couple cap changes is worth a post there. or anywhere really, but i guess this thread will do since the MT-2 is the largest circuit i’ve breadboarded so far. after fixing a few errors, the build sounded...

Brown Ball

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.
