I know, this is really not a pedal, but I think it's dead cool :D





Mmmm mmm mmmmmm. I think I posted about this in the synth-diy thread, but this is the finished article!

hey thats cool man
did you get the panel screen printed?

alanp

Front Panel Express. The art is engraved/cut into a black anodized panel. Very, very well done, but it better be. Why? You've heard the expression to charge like a wounded bull... think more bull you just kicked in the nads.

That looks sweet. What does it do exactly though?  ;D
I build pedals to hide my lousy playing.

That is quite cool, I'm wondering what it does? LFO? CMOS synth?

That looks crazy sweet!  Must make some really nice space ship sounds.

It's a copy of the Minimoog synthesizer's low pass voltage controlled filter.

And yes, it makes some sweet sounds :)

that is so great......man, super inspiring.

Do you have keys yet? If so, what?

alanp

No keys yet ;_; been using a FreqCentral Waverider LFO and System X Envelope to control it.

Got a sequencer in the pipeline, but hit a snag with the faceplate.

Very nice!

Was matching the transistors a bugger?

The Moog Ladder filter is one of the nicest sounding filters IMO.

The filter in my prodigy is just lovely.

I have built a few of these and in the first 3 I matched the transistors (BC550 I think), and in the now defumct EFM filter I just stuck em in. All worked fine.

Bit of a dredge, but would anyone be interested if I did ten sets of boards for this?

New revision, uses less HP (and panel space), all boardmounted, two stacked boards (think Brazen Bull, but less impressive.)

Count me in.  I still need to buy that sequencer board off of you.
