just finished the quadrovibe, and man oh man did Bean do a great job on this design. sounds wonderful. haven't played around with any adjustments yet. I decided to wire the speed pot in reverse so it would function like the "brake" on a leslie cab. I'm planning on adding an expression pedal jack in the open space on the right. I can use the same pedal I'm building for another project. I would reccomend wiring the chop trimmer as an external pot cuz it will make the trem a little more versatile. this pedal is a lot of fun. I kept playing "sleepwalk" with it and it was really dreamy sounding.
no problems dialing it in. etched up the charge pump board on the docs to save as much space possible. used a 3pdt swith so I could put led indicators for the trem/vib switch. made my own board mounted pots, and etched a full face plate.
tomorrow I'm gonna experiment with running my direct sound into a separate amp to see if I can get some univibe sounds.

Loos great! Nicely done on the two indicator LEDs. Do you have them synced to the LFO, or are they just indicators?
Very nice!!! This looks fantastic man! Great job!!

the main led near the stomper is synched, the trem/vibe leds aren't. I figured I would just run them from 9v at the dc jack.
Awesome job!
Man o man you and some of the others are really setting the bar high!
Great job!!!
How are you doing the metallic finish overtop?

Dude I forgot to comment on your etching! :D It's absolutely beautiful. Specially with the metal flakes over it...it looks amazing man. What font are you using for the Quadrovibe name if you don't mind me asking?
Is there a chance of a demo for this one? :) Lately I have been craving some sort of modulation on my pedalboard :-\ geez, does it ever end? haha

good job love to hear a demo with sleepwalk
Great job man. I'm going to have to try etching a face plate.
Love to hear a demo.
Good job, this one looks nice.. I would also like to see a demo. :)

me too! but unfortunately my computer is from the stone age. I'm not set up for recording, but I'm working on it.

it's just some metal flake clear coat I got at Autozone. It is very testy about what kinda paint is underneath, and doesn't like baking. you need to use very light coats, and use a plain clear over it.
I'm going to sound like a noob here, but how did you set up those indicators? could you give a little diagram of how you hooked those up. or just a verbal description. I've never hooked up a 3PDT toggle before in this application, but would like to!
Use a dpdt switch run 9v to your current limiting resistor then to the center lug on one side of the switch. attach positive side of each led to outer lugs and run the negative side of each to ground. use the other side of the switch for the pcb connections.
On another note. Just tried out the pedal with an a/b/y switch and 2 amps. A tweed deluxe reissue, and a mesa nomad 100 2x12 combo. I ran one amp with an uneffected signal and the other with the q-vibe. There was some very cool tones to be had. Not quite the phased out univibe sounds I was hoping for, but it yielded some very spacious lush tones without sounding "chorusy". Especially if one amp is run slightly dirty. it helps if you have a phase invert switch on your a/b/y switch. In phase an out of phase both sounded good but one was definitely fuller sounding. I can only imagine the addition of an expression pedal to dynamically adjust the speed while playing would sound fantastic.
Another great pedal from your work dungeon!! And honestly your workmanship keeps improving. All this talk of univibe makes me want one more!!!
Wow really awesome looking pedal! I'm going to building one and am thinking about taking your recommendation and wiring the CHOP control externally. How much does this open up the possibilities of the pedal? You think its worth the extra components?
no extra components just 3 short wires. the trem is very 1 dimensional without it. so yeah, it opens the possibilities. but the vibe is where it's at on this one.

So, on a 3PDT switch it would look something like this?
A B C
1 x x x
2 x x x
3 x x x
1A: LED +
2A: +9v
3A: LED +
And then treat the B & C columns like the DPDT on the project diagram? Hope that makes sense. Thanks in advance.

Yup, that'll work :)

don't forget the current limiting resistor!
you guys are awesome. thanks!
Finally got around to wiring up my q vibe. I tried pouring the chop externally like you suggested but I found out that for it to ve useful, you really need access to the gain trim pot as well because the difference between all the way up and all the way down on the chop is a big difference due to the lamp basically turning off or saturating. Thus, I decided to leave it inside and use the set it and forget it strategy. Five knobs would just be too many for me
