Just when you thought it was safe to go back in the water... This would have been my entry in the most recent MBP competition, except I couldn't get it to work in time for the deadline. Pulled it from the shelf of shame today and whaddayaknow, had inserted one of the ICs backwards. Should really stop doing that. In case it's not obvious, it's a Mad Professor Snow White Autowah clone on a GuitarPCB Swah board.

Had a number of accidents with the graphic, some happier than others. I've got another Swah PCB somewhere so may do another with less deranged graphics. I sprayed the laser decal with nitro that was apparently way too thick as the decal pretty much melted up immediately. Learned to do a mist coat first next time. However, the result was kind of interesting, as you can see.

Guts.
Brilliant! One of the greatest movies ever made
Whatever happened to the graphic made the water and shark look awesome. That's a nice happy accident.
I didn't realize it was messed up until I read it. Nice job!

Yeah, I think it looks great. Has a vintage feel to it. Good work.
I have one of those boards laying around in my random collection. Maybe I should think about building with it.
Looks awesome indeed! 8)
Wow, that does look cool, even if it wasn't intended!

Same here... Looks killer... really psychedelic
I thought maybe you ran the art thru Corel Painter or something for effect. It'd be damn hard to duplicate :-)

Will Corel still work on a modern computer?

I see what you did there :) Cheers everyone.

Very nice graphics !!! This circuit is really fun but I would highly recommend mounting the bias pot as a knob :/ you really loose a lot with having it inside as a trimpot imo ....!
I can only echo everyone above, great build. The graphics are perfect. I have a fuzzdog board of this circuit, how does it respond and sound compared to other filters?

That graphic does look great. Kind of like the whole pedal is under swahter....

Your best option for running an older program is to upgrade to Linux Mint and run a program called Wine. I've had a lot of success getting old Windows programs to run like that (probably better than they ever did). There's really no point in ever having to shackle yourself to Microsoft's "broken computer" philosophy.

Only played with it briefly so far but it seems to be a little too subtle for my taste. (Nothing exceeds like excess!) Would messing about with the bias make the effect more pronounced?
I built this one too & love it. A few tips for getting more pronounced effect: keep guitar volume up, hit the strings with some degree of force & set the resonance fairly high (you can reduce once you start hearing more of the effect).
Sensitivity knob is a bit odd - for me at least, setting it lower (9:00 say) means MORE sensitivity. Maybe I wired it backwards... Setting the bias trimmer in the middle or so wound up being a little darker so I went a little higher. I agree with putting the bias outside the enclosure, but it's not a dealbreaker. You really have to set this while playing.

I sold mine a while back but the way I remember it the bias trimmer controls the frequency of the filter. So let's say you wanna plays mostly low notes you would turn it down and higher ones turn it up to have a more pronounced filter sound.
If I were you I would open it up and play around with the bias trimmer, if you then think you would want it as a knob and don't wanna waist that oh so good looking on art, I am pretty sure that a 9mm pot would fit on the side of the enclosure, my guess is that you used a 125b enclosure, if so it should be talk enough to have nice and snug under the pcb :).
Do a forum search for autobahn, its an swaw type pedal on steroids. Kief can etch one for you; I believe it has everything you want. I prefer it to a straight swaw.
