Had a request for a clone of the eqd black eye boost recently. Basically a sho etc. so figured id just make up a board. Recently I switched to using an I/O pcb for dc and the jacks and ribbon cables (one of my best decisions ai think). Circuit is awesome really pushes my black pearl 30...

Anyone actually tried any of the vactrols on ali express. First thought is they have to be crap, has anyone tried?

So looking at the datasheet this appears to be internally connected but both of these schematics have me questioning this somewhat. Theres not a pin that available so I’t got to be internally connected. It just seems weird they’d label it v+ and I don’t see a “G” in the valve wizard...

ok so aside from what robert did with the flock any good suggestions for dealing with the height difference between most rotary switch shaft height and a pots. The slightly higher shaft annoys me. Obvious one is to just seat the knob a little higher up the pot shaft or cut off the end of the...

More just documenting this one. As I figure it out. Next step is to replace the jfet again with one from a different batch. So basically fully ccw the the pedal seemed to be working fine. As your turn the bias pot up it hits a volume jump then hit a volume drop and would get...

So I built a circulator and I’ve built one before and I dont remember there being a slight tick when the effect is on but your not playing. But it could have been there its faint enough. But anyways I can hear a slight tick of the lfo when not playing. Its not there in bypass. And you...

I've seen a few different circuits where the soft clipping diodes have a wire connecting between the two sets in between them. IE the Cast Iron Overdrive How does this effect clipping, is there any difference audibly if its not there?

I am looking at the Frequency Interchange circuit and am wanting to run it at 18v. I'll probably just end up doing my own layout for this and use a charge pump running a dual supply to do this. Can/Should I remove c1 and c8 from the circuit as vref is now going to be ground so I don't see...

Anyone use these? Im always hesitant on aliexpress stuff but seems to be the source for this style pinout which size wise seems like the best option for io boards. Curious if they are crap I guess.

I’m looking at adding a feedback loop to the parentheses mini board, basically just looping the output back to the input. My understanding is this one inverts the phase of the signal. Will i need to invert the output before going back to the input then? And to do this would I just use...

Anyone tried the gl5528 instead of the 5516 in the moonshot. I swear i had some but either i used em all or they found the parts blackhole. Difference is 10-20k light resistance vs 5-10k. Edit: sorry, compared it to the 5516, I’m trying it… just can only compare it to a demo when I’m done

Just wanting to do a simple high pass filter that is passive and would be in its own box. Goal is -6db at 90hz. Which i can get close enough here. Do I need to use Rin and RL ?

Obviously I can socket/breadboard which I’m going to do anyways. Just curious on what others have experienced with q2 hfe being 150-170. How much have you raised q1? Normally i do 70-85 q1, 120-135 q2. Have you ran into bias issues? Im assuming its a bit more compressed? Just...

So this is oscillating at higher gain settings. I incorporated an order switch so there is plenty of wiring in there. The oscillation stops when you play, and comes back when you stop. It almost seems like the whine from a fake charge pump. This is like #22 used from a batch from digikey...

Hey looking for STEM projects to do with my son, was thinking this arduino would be cool. As well I’d learn too. Anyone bought one the many starter kits and liked it? Or a suggestion for getting started.

Put this one together, don’t do too many build reports anymore but I ran into an issue with this one and since I dont see any mention of it anywhere I figured I’d write it up in case someone does. So I of course didn’t test this before boxing it. Got it all boxed up. And go to test...

Hey guys, Mjust curious if anyone knows if this will work. Friend of mine wants a box so he can have basically a second setting that he can hit the footswitch and activate and then release so momentary. I was thinking just wire the trs jack to momentary 3pdt, connect one side to the pot the...

Anyone know which hfe bucket the original used? Building for someone else looking for exact a clone as possible. Thx

I was screwing around on the breadboard recently with the mxr distortion + and decided I wanted to actually build one. As this is probably the 5-6th time ive breadboarded it for various reasons. I played around with a bunch of stuff and really liked the gray channel values sound. But...

So i pulled several of these out of some old amps and pedals i got a bin of free as they all didnt work. I think. Got a bunch of 3007’s some 3005’s old jrc 4558 (sound just like the new ones). Im assuming they are legit but id expect them to say mn on them which they dont. I...
