Do you have a strategy for PCBs with LFOs out of interest? If you are willing to share? No worries if not.

That looks really neat. I wish I could let go of the symmetry and arrange boards this way. What's the circuit? I like your staggered pots in the top row, I'm doing similar on my designs.

I was definitely going to enlarge those 47N caps before getting the board fabricated :LOL: But now I am going to have a long hard think about how to make the smaller switch footprint look bigger!

I've got about 15 separate projects on the go, but this is a Son of Screamer/Eternity hybrid with switches altering the high and low frequency response of the circuit. The hope is to get the best of both circuits in one. I'm building it for Christmas for my teenage daughter who is learning...

I've been reading back through this as I immerse myself in Tubescreamer info in preparation for a Christmas project for my John Mayer-loving daughter. Thanks so much for what you contribute here @Chuck D. Bones. Does the order of C4 and R8 matter? For example, the Eternal Burst schematic has...

@debrad I haven't tested it yet (due to the long and constantly-changing list of projects I'm working on), but my schematic did end up with a B10K pot blending both paths. The advice I got on another forum was that the proximity to the opamp stages was a benefit - but @jwin615 has pointed out a...

VERY late to this but I've been looking at TS10 schematics because I'm designing and building some Mayer-inspired pedals for my daughter for Christmas. The main differences between the ToneGeek TS10 schematic and the LGSM are: 1) An additional 220R resistor between C2 and R5 (LGSM reference) 2)...

Wow @Brett, what a treasure trove of information. I will probably re-read this a lot, thanks. You've already anticipated my thinking about having the LFO and power section of the Univibe on a separate board to the audio circuit, and with their own separate ground arrangements, connecting as...

I've come back to this thread like a proud grandfather. Didn't expect it to still be rolling 2 and half years later! I love seeing the stuff some of you guys are making. Quick question - any advice before I tackle my first stacked PCB design? I'm working on a designing a custom modded Univibe...

I'm often doing that, or using AI to generate enclosure art.

Even if you don't get it fabbed, it's good practice and fun to do. Your layout is really nice and clean. And symmetrical, which shouldn't really matter, but does to me. In turn, I stole the background colour idea from some Pirate Midi product shots. Coral goes so nicely with black.

It's not lost on me that some of my tweaks to the circuit came from the datasheet too. I wouldn't then claim that my variant of this circuit is designed to sound like an obscure and expensive amplifier. It's the exaggerated claims when all they've done is configure the part according to the...

Yeah I built a reverb into an amp project I made for my kids, and learned that J Rockett were selling a reverb pedal that is 100% datasheet haha

I've been on a bit of a tear with PCB design lately. This one is a result of playing around with the El Sol/Acapulco schematic. I found something reasonably funny while looking through LM386 datasheets, namely that the Acapulco Gold - famed pedal "based on the sound of a cranked Sunn Model T" -...

The Skewer fuzz: what you get when you combine a Meathead and a Doomstick II. (Meat + stick = skewer). I thought I would squeeze two one-knob fuzzes into a 125B and have them on a switch. I decided against 2 footswitches as I don't like 2 in this size enclosure. Using an on-on-on switch allows...

It's nice to see this thread still kicking at 10 pages. Obviously a lot of interest in taking DIY to the next step. Here's what I've been working on: It's a modified Life/Parentheses. I've recently fallen in love with this circuit, after realising how nicely it can be used as a dirty octave...

I was thinking about a potential mod to this circuit, where the Scooped and Full paths could arrive at a pot for blending, rather than at a switch for toggling. Would it work the way I am imagining if the Scooped path went R26 to lug 3 of a pot, Full went R27 to lug 1, and lug 2 connected to...

With the MMBFJ201, that's almost certainly the main driver of availability at the moment. A lot of manufacturers still have a backlog to work through from that period of time. The MMBF5457 is a different kettle of fish, once we use up whatever finite stockpiles we have, those are gone. I should...

If we look at parts availability data, we know that these parts exist in far smaller quantities than they have in the past. The reason I started thinking about this at all is this graph of MMBFJ201s from last year: The MMBFJ201s haven't been discontinued yet and are occasionally restocked...

Recently I've been messing around with the HM2 circuit and throwing around different design ideas. During that process, I've noticed that the stock of common SMD JFETs is seriously dwindling in the usual places I look. I know someone somewhere will have a stash of them - getting my hands on a...
