I used the 125B PCB and filed it a little so it would fit a 1590B box.
Sounds sweet :)

That looks AWESOME. Really simple. Labeling is just a gold pen marker?

Thanks.
Yea it's a gold pen, and the enclosure is prepainted from smallbear http://www.smallbearelec.com/Detail.bok?no=960.

I don't have enough time for spraypainting and decals, so I try to do the best I can with colored enclosures, knobs, layout and a pen :)

I did some beer-measurement so there was not enough space for a battery, but I never use battery anyway :)

I got the PCB from Haberdasher here at the forum.
It's jkokura's layout.

Nice build... the lettering looks great!

I love using gold paint pens for the lettering. I painted a pedal with that purple Krylon X-metals and used gold paint pen than clear coated - looks really cool.
I found some cool fluorescent paint pens at Hobby Lobby that i want to use.

Ah, cool. The board was the same kind I had used so I couldn't help but ask thinking we built the same circuit....but we didn't. :)

Nice build, any chance you'll post sound clips? Where did you buy that sweet LED bezel?

Very tidy build, Trond.

I've seen a couple of the European guys use those bezels, I don't know if there is a source in the states. They are pretty sweet looking!

Thanks!
I might do a soundclip some day.
Nice etch Keefe :)
The LED bezel is from musikding.de a German DIY webshop.

Ooh I like! You put the knobs backwards though :)
I still gotta populate mine from Haberdasher, some people believe this op-amp muff is the biggest, gnarliest one of all...

Thanks. I had to have the knobs bacwards because of the way i mounted the pots. Some ehx big muffs have the knobs this way. It sounds killer:-)
