After a heap of prototype boards and redesigns, I finally finished my Leslie-ish circuit! You can read a little more about how it works here (http://www.madbeanpedals.com/forum/index.php?topic=26406.0). Basically, the audio splits at 796 Hz. The low end goes through tremolo and vibe circuits (anything under 80Hz is unaffected), and the high end has simulated Doppler effect and cabinet resonance with a PT2399 chorus and then a tremolo and vibe circuit. The two pathways can run on one LFO to be synched or can run on independent LFOs. Each LFO can ramp between two speeds, and the ramp rate is controlled by trimpots (they are accessed by the two holes between the speed knobs). It has stereo outputs that can run summed mono signals, one output for high frequencies and the other for the lows, or 100% output of one signal and 50% of the other. There is a slight tick to the LFO, but I bet it would be eradicated with a 470u cap in the power filtering stage. At the levels I play at, it isn't really noticeable, but I'll really take a look at it later. For now, I'm gonna enjoy this beast!
For extra fun, I used three 1776 relay bypasses, one for the bypass and two for the LFO ramp switching. This allows me to use arcade buttons for extra cool factor. For the enclosure, I designed the graphic in Inkscape, printed it out on a photocopier, and transferred it to a powdercoated Hammond enclosure by rubbing acetone on it. The toner just slips right off the paper and onto the box!

That is seriously amazing. Well done, bud. Any chance we're gonna get a shot as these PCBs?
Fantastic work, looks great!
I too would love the opportunity to have a crack at building one myself.
Is the mild scratchy-ness from something in your effect chain, or is the 2399 being a bit over-driven? (and as a corollary, does it use the pin 7 green LED trick?). Or is it just an inherent part of the effect.
I'm just curious. It sounds quite nifty as is.
Impressive! I need one of these. Im in too for the pcbs, sure you send one of these to Scofield and you become next boutiquer of the famous! it sounds as good. Congratulations
Very cool. Obvious that you've put a lot of work into this.
This sounds so unique. Good job!

Thanks. Of course I'll get some PCBs made. I'll probably do so once I or a beta tester figure out the values to get rid of the tick.

I think it could either be the overdrive I'm playing through, iPhone quality video, or the noisy tubes in my amp. I'm thinking it's the overdrive. I have played this pedal with no other effects and don't hear any PT2399 clipping.

Scofield is a big guitar hero of mine. That would be cool...

Awesome, looking forward to this!
Awesome as always. I'm in, as usual, when you do a group buy on this.
Sounds awesome! Excited to try this bad boy out!
Was that Gymnopodie in the middle of the video?

Excellent, I was hoping that was the case. What a lovely effect.
Most excellent
Looking forward to the pcb
Sign me up, I love this one

Good ear. My uncle showed this to me a couple of days ago, so the melody was fresh on my brain. I try to avoid the usual guitarist stereotype and learn how to read music a little. I know a snippet of Claire de Lune and the prelude to Bach's cello suites (just to mess with the cello purists that I know), but my main focus has been the guitar works of Costé.
That's crazy impressive man.
Need! :)
That is the coolest thing I've heard in a long time. If you're making for a list of willing ENTHUSIASTIC buyers, I'm in.
Sign me up for boards. Awesomeness.
Gahdamn! That's a great sound! :o
Well done Chris! That sounds incredible!
Spectacular!
Another banger Chris! This thing sounds fantastic. Maybe this would get my dad off my back to build him a Vibratone. lol

fantastic all round! also would like to give a shoutout to the acetone/photocopy toner transfer trick that sounds very handy indeed
Love the arcade buttons ! Does it work well with your foot ? I tried to use this kind of buttons on my Ditto Looper, and it was not that easy to activate (which is quite a problem with a looper)

The great part is that you can do this on a plain, sanded enclosure or on a powder coated one like this build. I wasn't sure if acetone would eat away at the powder coat, it the transfer process is so fast, but the acetone didn't sit that long on the box. Some other ideas would be to print color pictures on a color copier for some lo-if, artsy designs.

It seems to work okay on my build. It takes a little balance to hit both ramp buttons at once, but it just took some practice. I put an arcade button on my EHX Freeze, and it works just fine for me. Nice and quick response!
