Nope, no change. Didn’t get to do much troubleshooting tonight, so I’ll leave it for the morning before work. Steps thus far: - swapped power supply - removed from enclosure and re-tested - checked for bridges, gave another clean up wipe, brushed off board Tomorrow, I will try swapping out...

Ok, not exactly sure how to describe what’s going on, but basically my most recent build (newest iteration of ADHD w/ enhanced bypass board) is making a high pitched squealing noise. When pedal is in True Bypass mode, the noise only occurs when the pedal is engaged. When the pedal is in Buffered...

Got it, thank you! Found a couple of sites that have the component differences for at least V1.1-4, so that’s a start. Should be able to sort it out.

Also looking for ADHD docs. The values on the PCB are fine for most builds, but building a specific iteration for this particular board would be nice, especially since I’m looking to do multiple different versions and have a few boards sitting and waiting.

So I'm looking at adding a switch to go between symmetrical and asymmetrical clipping, specifically in the Cast Iron overdrive. I've attached a schematic of the clipping diodes, and just want to make sure I'm thinking about this right. First, if I want to just make it asymmetrical clipping, can...

Never mind, I believe I answered my own question. When uploading the design PDF to Tayda's website, it asks you which gloss type you have selected, either matte or varnish. It does not appear that both can be done in the same design. Oh well!

Ok, so I'm finalizing a design and getting all of my layers ready in Affinity Designer. At the last second, I thought it would be cool to have the main logo done with the gloss varnish, and then the text/controls in the matte. Is this doable? The template that Tayda gives for the layers says...

Hmm. Yea looking at the schematic I’m not sure R5 would have that effect. Hum sounds like a ground issue to me. Squealing seems like a feedback issue to me. Have you tested it IN the enclosure and it’s not working? Have you tested it OUT of the enclosure and it’s not working? Both?

You may still need to jumper R5?

Appreciate it! I'm pretty sure I read something like that as well, but I can't seem to track it down. Something about "gain to max" and then bias. I gave the schematic another once over, and I think maybe I'm seeing what's going on, but I'm still a novice at this. Leg two of the "drive" pot is...

Please, sir. My crops, they are dying.

Cast Iron Overdrive (Lollar Overdrive). Basically a Timmy-ish with a mids control. Perfect for adding a bit of grit with a lot of control over the EQ section to boost/cut what’s needed. I use it a lot to boost the mids for leads and give it just a hair more gain.

Ok, I know there are a bunch of threads about biasing the Son Of Ben, and even more about just biasing in general, but I could not find an answer to this. I have built two separate pedals that need biasing (3-4 of each), one being the Son of Ben (Benson Preamp) and the other being the Taqueria...

Paper size should be "Letter" (8.5" x 11"). Print scale should be "Actual Size" or "Default" or something along those lines. What exactly isn't lining up? Pictures?

LED bezel? I had this exact issue with a build. When I would tighten down a specific pot, it would short. Drove me nuts. Turns out that once tightened down, the pot was contacting the nut of the LED bezel, which was in contact with the washer, which was in contact with the enclosure, which was...

We need pictures.

Occam’s Razor? Im guessing you did, but did you make sure to turn the volume and drive knobs clockwise? If so, next step would be double-checking the polarity on electrolytic caps, but they look ok based on the build docs. After that, it’s audio probe time.

Thank you both! So, from what I gather, it’s mainly the digits that I’m worried about. So the JRC or NJM or RC doesn’t really mean much, it’s just the 4559 portion that I need to focus on?

Hey all, I have a couple of builds coming up that call for the JRC4559D (Sliver and Stagecoach), but sourcing this part seems a bit difficult, with the only real option being AionFX. I will also be building a Cast Iron soon, which calls for the RC4559, which is readily available at...

Lytt Effects is proud to present the: Benny the Jet The PCB: obviously from the fine folks here at PedalPCB. The layout of this one, like with most projects, is easy to read, follow, and work with. The bias instructions are also super helpful to get it into the ballpark, and then adjust to...
