Love it! Tell us more about the alcohol ink sides. Process?

Thanks,
John

Probably the best thing to do to check out alcohol inks and how to use them is a look on youtube for tutorials. It is a very easy and quick process, applied over bare metal.

Nice build !

I like to add metal or plastic faceplates on my builds too.
Pots and switches conviniently act like giant screws to hold them on the enclosure.
"unity-gain non-inverting stage", "ground leg","post-pick moments", I love this colorful forum.

New year, newly completed build. Timmy clone -> Straight Up clean boost -> Notorious OD in a 1590X with reversible order.





I may paint it one day.

The Polytrog - EHX Polyphase. Took me a long time to get this one together. For some reason, I recently watched a 2-hour long documentary on youTube about "Gorefield" - the Cthulhu/Old Gods take on Garfield the cat. So I used that as inspiration for the artwork. Etched on .033" 2oz black FR-4.

Looks insane! Could you please share the link to that documentary? I'm eager to watch!

How'd you manage to find those optocouplers? PCB is yours, or you bought it somewhere?

I got the optos from Scruffie (they came at the perfect time). The PCB design is mine. I actually went through something like 4 different layouts for this one. It was a labor of hate, haha.

Here is the youTube video:

I like to add metal or plastic faceplates on my builds too.
Pots and switches conviniently act like giant screws to hold them on the enclosure.

I find that a lot of pots I have only have a few threads and cannot be used with a metal enclosure (even a stamped sheet metal one) and a piece of plastic.  I ran into that on one build where I was using a plastic sheet behind the metal that had holes for the anti-rotation tabs because I intended to use chickenhead knobs and the holes would show.  Some pots have as much as an inch of threads but a lot of them have only a quarter inch that has to accommodate the metal, the plastic and the nut.

Our favourite Alpha 16mm pots and many similar brands have just enough threads on the bushing for a Hammond enclosure (usually 1590N1 in my case - typically about 2mm thick), a lock washer, the thin dress washer and nut.

I build modular synth modules as well, and for my own designs often use 3mm lasercut and engraved acrylic. Usually do not have an issue with 16mm and 9mm pots, but the nut is often precisely on there, switches are never an issue, the pc mount 3.5mm mini jacks (eurorack) need a little countersinking from the back (they have a little collar) to allow a nut to be fitted.

Blues Driver

A first perfboard build :





It's a bit crowded in there, I need the plastic bag or the board gets shorted by the back of the enclosure :



based on this layout :

http://effectslayouts.blogspot.com/2017/01/boss-blues-driver-2.html

Tone control is B25k instead of B10k, Drive is a stereo A500k instead of A250k (too light). Working with 4x 2SK117GR instead of J201.

The switch on the pics (sym / asymetrical clipping, no audible change) has been replaced by an other one, allowing to change from stock to bass decrease and mids boost. It changes R12 (1M to 75k) and R11 (from 15k to 47k). It gives a slightly brighter sound and a bit more gain with a little more mids presence.  Based on this article :

https://www.analogisnotdead.com/article25/circuit-analysis-the-boss-bd2

It took half a day and half a night to build it, 1 or 2 hours for the "artwork" (I didn't really think very hard on this one).
Sounds amazing, I strongly recommend this layout.
