First and foremost, it sounds fantastic. I absolutely love the harmonic percolator, and I have assembled quite a few PCB’s. This is my first turret board build, and am looking for honest critique. What could be improved at first glance? I am aware of come jank, esp the led resistor. I found...

Excellent! I’m embarrassed to admit but this idea never even occurred to me. Found the schematics and service manual, all it says is silicon diode but it confirms things. Super helpful idea, I have a pile of other electro with questionable components, looks like I have some detective work ahead...

I pulled a pile Of these diodes from a Hewlett Packard pulse generator. Unknown era, but my guess is 1960’s. There looks to be a Fairchild “F” on the base but I cannot confirm. Vf according to my Peak is .595 to .659 @ 5.00 mA. They are black glass, brown stripe at cathode end and a yellow in...

Question: I am getting some static and crackle when the pedal is on, but not playing. The catch is, 99% of the components are reclaimed from older obsoleted electronics. I have swapped transistors so it’s likely not that. Any suggestions as to where to start? I wanna say I’ve had this “issue”...

I bought some obsoleted electronics at a local recycler, and there are a ton of these jfet’s. I am having trouble identifying them. Markings are “S” and “F2701”. They sound good in a simple DOD 210 FET strip board circuit. Mostly curious what they are or what they compare to The IDSS for one...

its a Hammond enclosure, maybe a 1590XX? Its whatever the build docs state. I dont have a drill template, I just printed the one that was in the build docs, but I enlarged it to the point it was an exact match to the actual PCB

I am making my first attempt at wiring a circuit using stripboard. HP-1 because I like it and it has a reasonable number of components for my pea brain to grasp. Plugging all the components in is easy, but I am not sure about the footswitch. I have a 3PDT footswitch, how would I wire this...

Thanks, of course now I realize its listed right there...

Thanks all, really helpful. @Ginsley, do you happen to know the value of the trimmer in the second pic?

Guys, not sure if I wasn't paying attention this past month of using this pedal or not, but I have noticed some popping upon turning this on and off... 1meg resistor on the input jack? Of is there something else I should be troubleshooting?

I am a visual learner. I have the schematic, but I am still very very new at deciphering them and how everything flows. My request: If you have a breadboarded RG Keen style leakage tester that doesn't stray much from the actual schematic itself (I have seen some w/ switches, trimmers...

@HamishR thanks for the idea's. One issue I also have is the hook up wire is super floppy. I might need something a bit "stiffer" so I can train it to stay put. But I agree, maybe I will run it all under the pcb. It sounds great. I havent been able to set the distortion and compressor trim...

yes, correct

I went through a preamp phase last month and between this and the IVP Preamp build I think I am set (yea right) Overall, this was an easy assembly, just a lot of parts. No traces to score for loop wiring, just a crowded PCB. Swapped the called for 4558 opamps for Burr Browns because I am a...

I just finished the build, did the loops because I knew if I didnt, I would regret it. Even if they are not used all the time lol.

All, Apologies for resurrecting a long past thread. I am currently building one of these as we speak and I am crippled with indecision regarding the effects loops. I get that the usefulness of one in a pedal is limiting, but now is the time for me to decide. So, if anyone was to do it...

Great idea. That rotary switch takes up a lot of space it seems

Man, I would love this in a 1590BB. I have zero need for the fuzz, is it possible to make that optional? Or modular for those who want the fuzz? I just dont think the evil filter fuzz sounds good.

yea, Ideally.

Hi All, Apologies if this is a basic question that has been discussed ad nauseum, but being a noob at this sort of thing, I guess I have to ask to learn. Long story short, I have a DBA Evil Filter pedal. Two things: Its f*ing massive, and I have no use for the fuzz side. What would it take...
