Single knob Univibe

[Chistopher]

I'm still in the thinking stage of my Psychadelic Machine idea (however I did find a nice enclosure at goodwill that's definitely very late 60s) and I'm still deciding if I want to try to condense the univibe into one knob.

I definitely only ever use mine at high speed and low depth or low speed and high depth. I don't think I would miss having a level knob, especially because the Vibe/Chorus switch does the same thing.

What are y'all's thoughts?

The vibe/chrous switch is not the same as intensity at all. The vibe side is pitch shifting, and hard to work into a tune. In 'chorus mode' the intensity lets you go from subtle movement in the chords to liquid lead lines all the way up to psychedelic melt down throbbing. I'd want to keep those three settings at least, otherwise you're missing out on a lot of what the circuit can do.

Well the Univibe will be used in tandem with an always-on fuzz, so keep that in mind. By putting the vibe on one knob and one switch, I'm losing quite a bit of flexibility to focus the sound purely on Psychadelia.

Yeah, in that case just a knob for speed with the depth set pretty heavy would likely work well.

This could be very interesting.

I will say, a couple of dangerous or good areas...It has to maintain a distinct "Vibe" personality throughout, not ramped down being a chorus or cranked up into phase land. I think that would be very cool if it could maintain that.

Or it could go from light chorus to vive to phase....But I'm not sure if I'd be more or less happy with that. I think I'd want a Vibe that was a Vibe through the whole spectrum.

I'm not a Vibe guy, so not my thing really. I just want tit to not be a Phaser or a Chorus. I have those if I want them.

 

[Chistopher]

Yeah, right now I'm thinking that having depth and speed on the same knob with one wired backwards would yield the most useful positions, but it would also have a lot of useless positions.

Right now I'm messing around with a cheap line6 modeling amp I found that has a single knob flanger with this configuration and I'm not really feeling it.

I may have to just go with two knobs.

Do a trimmer pot inside the enclosure. It’ll probably be around 90% but that way you can set and forget.

 

[Chistopher]

That is also a good option.

You can get close to a Univibe with a Phase 45 if you switch out 2 resistors to make the waveform asymmetrical, I put a switch for that on my GGG Phase 45 kit.

I always use a vibe in chorus mode, so if you need to set the swtich in your circuit, that is the setting I would use, of course, YMMV.

Oh heck! Didn't even think of the Pickle Vibe!!!!

A single knob Univibe would be best implemented as a pedal

Fret not, there will be an expression out, much like the original Univibe

I'm actually interested in trying the GGG Phase 45, I almost considered just putting a Phase 90 in because it's an easier circuit to tweak.

How much of a difference does your switch make? I'm gonna use a speed knob, but I'm between a 45/univibe switch, a depth toggle, or a vibe/chorus switch.

 

[Chistopher]

Yeah the more I think about it, the more I'm digging the phase 45 / Univibe idea. The question is, what to label the toggle switch so it doesn't scream "Fake Univibe / Phase 45". Maybe like Woosh/Warble or something.

Why not just vibe/phase or sym/asym?
