Ordering parts for a Lumitron and just need a gut check on this rather odd value mlcc (C15 470nf) called for in the power section Is that extra (and seemingly negligible) capacitance really necessary when it is in parallel with the 10uf electro? Does the nature of an mlcc offer some superior...

Was approached today by an acquaintance asking if it would be possible to make a Mu-Tron III based pedal that could be switched at will between EF and wah (with the use of an expression pedal). He wants his board real estate and cake too. Thinking on it my plan would be to (somehow) put the LDRs...

Was approached by a fellow marching band dad who plays trumpet in a few local bands who really wanted to dip his toe into the world of pedals. After setting him up with some of my personal pedals to try out he decided that these were keepers and commissioned me to build some for him. He said he...

Long story short, the L78l33 in a recent HAARP build is putting off 6.7v to the eeprom and FV-1. The effect is there, just distorted when hit with the lower strings. How long can these chips withstand that voltage, are they baked now? Data sheet says max v for the FV-1 is like 3.5v. 5.5v max for...

Legit cure for tube rattle or snake oil? My Swart 6v6se has some wicked rattle that I’d like to put in check.

Hot off @steviejr92 CNC and brake I saw these and needed one. Not really wanting to go down the Ge tranny circuit rabbit hole to build what it was intended to emulate I opted for a Kazoo instead. The Kazoo is a simple but unique fuzz that I just really like. The only change from stock is that I...

Is the Kazoo Horn switch really an SPDT on/off/on? Looking at the schematic it really doesn’t appear to be offering 3 options. The last one I did way back when I think I just used an on/on and that seems to match with the demos I’ve seen.

Anybody got a schematic of this pedal? I was given one that isn’t doing the fuzz. Probably because the “Dry” trimmer is jacked and stuck on all clean, but would like to do a more thorough investigation before just replacing the trimmer.

Yup. All this talk about flangers gave me the push to finish this behemoth. I have built a few of the larger AionFx projects, but I have to say this was the most intensive one yet. 16 jumpers between the footswitch and main boards alone. The build docs weren’t lying with their warnings. At least...

So for this Bronco bass project I have going, has anyone ever tried filling holes in a pickguard? This came with some J style bridge and pup covers that I don’t intend to reinstall, but don’t want to buy or cut a new pickguard because……cheap. Was thinking JBweld, but am open for suggestions

Having ideas and need to get suggestions. Ideally this would be a 4 state intelligent relay channel switch off one footswitch. Want to use it for toggling 2 fx loops, state 1-both off 2-loop 1, 3-loop 2, 4-both on. Having the ability to have LEDs corresponding would be exceptional. Anyone seen...

Was looking for a more challenging build and since I have been predominantly ampless, was looking for a potential alternative to my Quilter superblock UK. So when AionFx dropped their sale more than a few months back (not the last one) I grabbed the L5. Had it not been for the digital BOM, this...

I see on the Broughton website that the LP/HP has a 1M input impedance and suggests that it is high enough to accommodate acoustic pickups, but would it be beneficial to buffer the piezos in my stick bass (there are 2) before running them to the frequency interchange? I am planning to replace...

Never really thought ab it, and so long as you measure accurately it doesn’t matter the units, but out of curiosity, are PPCB drill templates measured in imperial or metric units? I tend to use metric since you get fewer trailing decimal points. @Robert ?

Calling @DGWVI and @Mentaltossflycoon and anyone else who might have thoughts. Mkay, not the reason I thought I was going to open this thread, but while my vibrobot is trem-ing, it has some distortion/fuzziness on the signal. After chasing rabbits before lifting pin 6 I am 99% sure of parts...

Awhile ago I presented a unique project to @steviejr92 it took a lot of planning on his part and time waiting on his new brake and cnc to fully realize the scope, but man did he come through. Some of you may have seen the teaser in the What’s in the Mailbox thread, some of you on IG may have...

Anybody know of a resource that shows the frequency responses of some of the more common speaker cabs out there? Thinking ahead on how best to use this Unicab board once I get it into play. Tried the Omnicabsim users manual but came up dry.

So I got caught up in the Aoin fx sale frenzy and ordered the L5 pre Board. I had been looking at it for a while, but never pulled the trigger because of the lack of a balanced out. Well that and the $16 converter, but why let a little thing like money get in the way…. I know I had asked before...

Not a new build but I took this out of a combo build using an acetylene as a pre and it’s just been sitting there begging to be boxed and used so here you go…… The power Jack got a little off center, but it doesn’t make me go into a white knuckle, eye twitching rage at its abhorrence and...

So my build inertia has pretty well hit the wall, but I do still build some stuff. I have been pretty meh ab posting my bare bones builds. So why start now? Because reasons. First up is a Tearjerker Wah with all the Chuck D Bones bass mods: First let me say, if you are planning on building one...
