Another BMP fuzz; Green russian with no mods.

Handmade enclosure with hammertone paint. The switch cap and face plate was etched with NaOH - see tutorials.

A tremolo and a reverb (belton brick). 

To fulfill the wishes of the customer, no extra mods or knobs for this one. Actually, to set the reverb length you need to open the enclosure.

The enclosure was handmade. If you want to try it yourself this document could be a help. And this spreadsheet for calculations.

Phase 90 with vibe switch. 

I tried all suggestions for a rate indicating led, but none of them worked. They did not work at all, had way too small intensity amplitude or turned the led on and off rather than made it pulsate. So I designed my own using two darlingtons (PCB). I’m not claiming it is the best way to do it, but it works.

The box was reverse etched, which together with the hammer paint was a nightmare. I won’t be doing that again (famous last?), but if you do, I have one advise: don’t try to sand the unetched areas (the text in this case) - use a knife to scrape off the paint.

A fuzz with switches for tone scope and clipping mode.

A tone bender based on MP20B transistors.

I made the enclosure by cutting an aluminum sheet with a jig saw and bending it with a home made bending brake. Finished with hammer paint and a reversed etched plaque.  

Gut.

A Korg DST-1, which I am fairly sure is identical to Yamaha DI-1.

I have added a diode selector to switch from between silicons, germaniums and LEDs.

The enclosure was etched, normal and reversed, and polished.

Gut shot.

PCB.

A tonebender on steroids. Russian transistors (GT108G) with such a high gain I had to add a separate gain knob - a 10 K pot between the emitter of the first transistor and ground. If turned all the way up, this effect gets really nasty (in a good way for some sounds).

My first 1590A box as well as my first reversed etch. Quite happy with how all the thin lines came out. 

It was painted with engine enamel. I can really recommend it. After 15 min in the oven it gets rock hard.

Gut shot.

PCB.

Tubescreamer with the following mods:

Clipping switch: Symmetrical, asymmetrical and hard clipping.

Range: 0.47 µF capcaitor in parallell with the 47 nF capacitor from pin 2 to ground. A 10K pot in series with the 0.47 µF capacitor lets you widen the range of the overdrive.

The labels was done with diy dry-transfers, with a slightly new technique.

Gut shot.

Another Echo Base delay.

I used the same mods as for No 17, but with a pot for shape and a footswitch for modulation on/off. The circuit is pretty massive, but luckily you can buy a two-layer PCB from musicpcb.com.

The enclosure was etched with NaOH and PnP blue as the mask. The back was however labelled with UV curing ink:
