New "Univibed" Phase 45 -- Wirbelwind

[petemoore]

The one I built the other day is too tight for this...but I'd like trying it...
 Make the 10k resistor [7k5 on DOD] coming from pin 1 to the speed knob...make that resistor larger [like 27k or...
 Then make an alternate path for that resistor that can be chosen with an SPST switch...make the resistance for that path variable...and you have a slow/fast sweep speed switch.
 I did put a switch for alternate resistance to make a 'slow/fast' switch mod, but 10k is soon 'dwarfed' by the rising resistance of the 500k pot...toward fast settings the slow/fast switch has just more than a doubling of speed effect...toward medium or slow settings the small [in relation to the 'up to 500k' resistance] resistance change has No effect [no discernable effect] on the speed...by starting with a larger value for the 10k, [say maybe substituting a 100k pot for it] an more effective adjustable fast/slow speed changer switch mod would probably work well.
 As it sits the [limited application] speed switch mod works great...increasing the adjustability of it would make a very nice mod I think...being able to adjust two different speeds and choose between them on a switch...
 Of course this could be done by simply adding a treadle control to the existing speed pot...
 At any rate [no pun lol] there are mods that could be done around that speed control...
 Really great sounding circuit, I was using Fetzer>Wah>BMP>45>amp...and I'm getting a very sweet vibe wobble, quite usable...the superb sound is a welcome addition...sounds different [maybe more 'compliant', forgiving, or clearer?] than my other three phasers...doesn't seem to mind having a gainy input signal.

grabber orange?

Wrong car company...Grabber Orange was a Chrysler color

It IS _____________ Orange, though

What kind of finish did you put on the box to give it that flake kind of finish? It looks seriously badassed! Did you use decal stock for the labeling or something else? Very smooth! How did you do the red and pink part on the bottom? Sorry for all the questions, but I'm very impressed with your work. One last question, can someone give me the mouser #'s for the aluminum knobs? They look amazing. It looks like you found a gold 3PDT somewhere, or maybe it's just your camera?

The top of the box is swirl sanded aluminum...I use an orbital hand sander with some 120-grit paper to get that finish.  First it has to be sanded smooth so that all the imperfections are sanded out, then I tip the sanded up on the edge of the paper and make random swirls and stripes on the aluminum.  Then I use some masking tape to tape off the top of the box and then paint the sides of the box with whatever color(s) I've chosen for it.

For the silver stenciling on the sides (Argent Silver...the color used on Chevrolet Rally wheels...another hint for the people guessing on the main color!) I use a piece of flat corrugated steel as a stencil.

The labels are the laser printer decal sheets from Small Bear Electronics.  I put the decals on after I've painted the sides and then I give the entire pedal one coat of clear to prevent the aluminum from oxidizing.  Once the decals have dried I give the entire pedal 2 more coats of clear lacquer to protect the decals and give it a nice shine.

The switch is silver...the flash on my digital cameran and the iincandescent lights in the room made it have that goldish tint.

The Mouser part numbers for the two larger knobs (0.87" dia.) on the top is 450-2225.  Those are $1.92 each.  The part number for the smaller knob (0.71" dia.) is 450-1825.  It's $1.74.

Is that real 1969 Z-28 Hugger Orange? Actually, I think they called it "Monaco Orange" on the 'Vettes, but that's neither here nor there, it's the same color. That's too cool!!  
Exceptionally clean build as usual, BTW!

Almost.  Hugger Orange is a little brighter than this color...more orangey.  

It's actually "Chevrolet Orange", the color that Chevrolet painted its small block and big block engines through the glory days of the muscle car.  Then they switched to boring black on the engines  It's a very reddish orange color, but I really like it!
