If I wanted to make the circuit a bit less bright, say by 25% or so, what would be the best way to accomplish that? Thanks for any help! https://docs.pedalpcb.com/project/Cobbler-PedalPCB.pdf

Just used my last TL019’s and have a Tactical Fuzz to build. I’ve got a few TM019’s and was wondering if those would have any audible difference? The difference I’m seeing so far is in the primary resistance (M is 600 ohms and L is 450 ohms), would that have any impact using them as a pickup...

Seems the converter needed for this build (IAB0105D12) is now obsolete. I did happen to notice Newark had 20+ of them in stock now for under $3 a piece. If you’re planning on building one of these, maybe a good idea to pick one up...

Just finished a CJ build and while the pedal sounds pretty good, the buffered bypass not so much. All of a sudden my Rockerverb sounded a bit anemic and almost as if it lost its character. Unplug the pedal and it’s full bodied and crystal clear. The difference is subtle, but definitely...

One of my all time favorite fuzz pedals. Love the sub octave “trombone” effect you get when the circuit is starved with the Mood knob and Range toggle. Also, very responsive to your playing. Dial the Mood knob back a bit and play softly, you’ll still get that sub octave sound. Although, pick...

I really hate to do this. I recently had an issue with a TS808 popping, that @music6000 kindly pointed out that I had an incorrect resistor installed. In that thread I had mentioned that I had a Skeptical Buffer doing the same thing. After replacing the usual suspects for leaky caps (all...

So, I’ve been scouring for the last couple days, read the AMZ article and combed through the forums. Found a lot of helpful tips and suggestions for solving this. My question is, what could cause switch pop when LED is engaged in a particular TS (the LGSM pcb) build, when all others have been...

Got your Vibrobot all built up only to find there’s no trem? Try clipping/lifting pin 6 of your 8038. Apparently some will work without doing so, mine didn’t at all until I did this. Huge thanks to @DGWVI for the info!!

I see there are a few folks on here that have had great success with the GPCB Buff n Blend circuit and I’m hoping someone could shed some light on this. I’m sure I’ve overlooked something. I’ve built a Univox Super Fuzz and want to add a clean blend to it. Super Fuzz tested perfectly. Wired...

Can anyone confirm if the Two Tone Fuzz has the typical CBE layout or is it ECB for GT402’s like the original? Thanks!

I recently looked to see if this guy was still on the “coming soon” list and didn’t see it there. Got all excited, then realized it seems to have disappeared from the website altogether. Was it renamed and I missed it? Curious if this one will be available in the near future. Thanks!

Alright, I’m stumped. It’s been a while since I couldn’t debug a build. I’m hoping one of you kind folks could help. I built two AionFX DZ4 (VH4 Preamp), one works great one does not. Did the usual continuity checks and everything checked out. Traced signal path with the schematic and...

Has anyone heard of/used the Philips ON4292 MOSFET? I recently purchased, what was described as “Philips BS170” and instead received Philips ON4292. I didn’t find a ton of info on these, or whether they’re a direct replacement/different manufacturer number for the BS170. Curious if anyone...

After building a couple Death By Reverb pcbs from PCBMania and being disappointed with a strong muffled/super dark tone on both, I stumbled across the Space Is Fun by Moonn Electronics. Not only does this pcb just nail the RM, it’s got a couple mods to choose from as well. One is a dry kill...

Stumbled across these and thought they’d be great for the Carbon Fuzz and other circuits that require low hfe silicon BJT’s. Just got some in and they all seem to be in the low to mid 80 hfe. For whatever reason, description on below link says 2n3904. Once you click on it, you’ll see they’re...

Hello All, Hope the PedalPCB family is doing well. I recently came across some pcbs that don’t offer drill templates (Moone Electronics) and thought, rather than to draw/measure free hand, there’s got to be software (or something) available to do just that. I’m not great with computers...

Just finished one of two last night. Used an MP38 (88 hfe with very low leakage) and two BC108b’s (319/322). Biased MP38 to 4.5v and it sounds fantastic! Also, used a 15k trimpot (just in case) but I’m not sure it’s needed as it seemed that 10k would work no problem. Gonna audition a few...

First of all, this is just amazing. Fell in love with this fuzz mere moments after first activating the pedal. Then I hit the second footswitch…. I’m done folks. I’m not a fuzz aficionado by any means, but this is probably my favorite so far (I keep saying that, but it’s true, I swear!). Not...

I’ve built a handful of these (cause they’re awesome) and on the last builds I could’ve sworn each of the three foot switches (Boost, Octave and Distortion) could be activated independently from one another and not like the EQD version where the Distortion had to be activated for Boost and...

I don’t suppose anyone has built this yet, or if Robert has a diagram for the footswitches on this one? Much appreciated!
