That could happen if you are using a LIN pot instead of a LOG pot, or if you have the LOG pot wired backwards.

I did use a 500k LIN pot indeed, because I did not have a LOG type, so it's a long travel from 50k to 500k and with a LIN pot nothing much interesting happens in between.
The most interesting sounds are really in the 47k, 100k and 500k positions, and I will eventually go for the 3 position switch to keep it a true "Tri-Vibe".

I guess the size of this circuit is as much as you can pack in such space without going to surface mount devices.

Yes, for me it probably is.
I made a PCB with the same size for Mark Hammer's "The Woody" and with 2 Quad opamps and quite a lot of caps and resistors that also was a tight fit,
but I see it as a challenge to make rather big circuits fit in a 1590B enclosure.

No Fender amp has pitch vibrato though. I think he's just using two Fender amps, one calls it Tremolo, one calls it Vibrato. Same Volume-WaVeRiNg effect.

No...
Some of the "brownface" fender amps use pitch based vibrato.
There is a project or two of RG's at GEOfex that simulates this.

Andre, nice work. So, anybody going to do a run of boards? John?

El Heisenberg · « **Reply #63 on:** December 31, 2009, 09:13:35 PM »

I just looked at the two vibrato circuits at geofex. Has anyone tried them?

I'm in the process of building the Vibro-Matic III from the Stompbox Cookbook, and the circuit looks fairly similar to this Tri-Vibe. I listened to the soundclips and they sound different, but not radically so. Do you think it would be worth it to build a Tri-Vibe in addition to the Vibro-Matic III? I have around 7 overdrives on my board, so 2 different vibratos wouldn't be pushing it, right?

El Heisenberg · « **Reply #65 on:** December 31, 2009, 09:38:02 PM »

7 overdrives jesus

Sadly, that's not a joke. 3 are TS derived too...

There are two in mark m's gallery here.
http://www.aronnelson.com/gallery/main.php/v/MarkMs-Gallery/album15/album76/Vibrato+LAYOUT.png.html
Search for brown face vibrato or vibratone and you will get a bunch of info.
There is an error in the layout of the V2 vibrotone(with the level
boost) so if you make that you should trace the layout vs the schematic
and adjust for it.
The first version is fine I think.

never use PCB. I just look at the schematic, and usually start at the input. I know I need better planning, but I do this just for myself, mostly

Very appreciative to Andre and all - but does anyone know if ROG is working on a PCB as well ?

Thanks, Dan

The soundclips are very, very impressive. If anyone records any more, I'd like to hear a Leslie approximation at high speed.
I've got an empty wah shell that I think would be perfect for this.

PCB coming up.
Sorry for the wait guys.

Thanks, sorry I missed your original post. Are you using Andre's layout or making a new one?

John Lyons · « **Reply #73 on:** January 02, 2010, 07:18:29 PM »

Well...I had done my own layout but I wasn't happy with it and I boxed myself in in a couple places.
I redrew it with Andre's layout as the main framework, then moved some things around.
It's almost finished...Stay tuned.

John

Check out my finished Tri-Vibe:

Not too happy about the hole for the LED, but for the rest I like it a lot.

El Heisenberg · « **Reply #75 on:** January 03, 2010, 05:30:54 AM »

looks spectacular

Very nice work! Thanks for sharing it!

Looks great!
Did you use a printed transparent sheet on the enclosure?

Andre, do you take orders for a PCB?

Ben N · « **Reply #78 on:** January 03, 2010, 08:14:20 AM »

Very Fenderish esthetic--Leo would be proud.

Fuzz Aldryn · « **Reply #79 on:** January 03, 2010, 08:32:09 AM »

Hey Andre,

having trouble here with your posted layout. The signal passes the circuit unmodulated though checking the voltage tells me that the lfo is clearly working. I have to double check my build and your layout w

Regards
Helge
