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...

Trying to upload a gerber to jlc and I’m doing the same thing i always do and the text for this faceplate isnt showing up. My other faceplates are all loading fine and showing. Only thing i can think of is im using a different font, could that cause this? The outline which is the same...

It has been awhile since I’ve posted a build report. I have one of these for me already. And i was trying to come up with something special to do with this LMS powder drop from September… Good friend of mine has mentioned a few times interest in having one, and his birthday is coming up...

Ok so i feel like it matters here but will make my layout a lot easier if it doesn’t. After the 10k resistor does the signal have to hit the nodes in order ie if my trace goes to the 2n2 (which now has a tone control pot) with a intersection heading to the clipping diodes that then goes to...

Exactly what the title says. Anyone know of any other pcbs available for something similar? I know fuzz dog makes one, reviews mention noise issues. And Moonn does as well. Also theres the xr2606 chip which looks like youve got to take the ebay gamble on. Wondering if anyone knows of...

So i finally pulled this board out and saw the gotcha resistors. 2M7 (just when you think you have every used value on hand lol). So anyways these appear to be a voltage divider. I could easily do a series thing but I always that. I was thinking id just shove a 2m2 or 3m3 there, but i...

Is there a way that I'm just completely missing to change the default making on components. Or even better batch change them. So in the pcb editor I want to have it show ref des. Then at the end is here an easier way then going through every component to change it to show value instead of...

hey all im looking for some russian germs in the 60-100 hfe range. My last gt310b’s out of 100 i got one in the 90’s everything else was 100-150. All very usable but im lacking for FF Q1’s at the moment. Thinking of picking up 100 gt309e’s but the price is a bit higher than ive been paying...

Just thought I’d share a pedal building dumbass moment. So i recently built a pedal for a guy it was more or less tweaking a circuit. I breadboarded the idea biggest thing was getting the tone stack right, and i felt pretty good about it. Went with a baxandall active. Get it all done...

Anyone have a working desolate fuzz that can share their ic voltages?

Would the difference be noticable if the 5v1 was subbed for a 4v7 here? Turns out my one 5v1 is shortrd.

Ive seen some talk of this with a body control. Im assuming they are just replacing the tone pot with the muzique two knob bmp tone stack. Anyone know any different ?
