nomad reverberola schematic in here

[pinkjimiphoton]

i rebuilt the broken track on the sliders on one of these a few years back for my friend ari in nyc, recapped etc.. this is a precursor to the univibe. whats different is that it has a tremolo mode in addition to the usual vibra chorus, and a switch to make the lfo double in speed. the tremolo full rate is like hendrix's own mosquitoes buzzing thru your chromastones n shit...
anyways, i didn't take the time to trace the circuit when it was here, but i did take a crummy phone pic. best i can do.
i had lost it for years somewhere on a disc i found recently so i figured someone could use it or may diggit or whatev. not that much new under the sun, ya know?
anywho... here ya go. i believe if you enlarge it some in your favorite gimp or irfanview or whatev you should be able to make out the values.
rock on pedaleros.

Thanks!

I wonder if discrete oscillator sounds any different from op-amp oscillators you usually get in Phase90 and alike.

That's crazy it has "reverb" in the name.

I think it's called "Nomad Verberola".  When I saw that name I had a feeling it got twisted from Viberola.  It's a lot like a univibe.

Back in 2004/2005 CS Jones traced the Jax Vibrachorus.  It's very similar to the Nomad.
It's got the same kind of switching.  I can see some differences around the front end where the Jax has 1k, 3k and 1M instead of 1.1k, 3k3 and 1M2.

I'm having trouble reading the SVC-1 values.  The Jax values are a good guide.  The only one that looks hard to judge is the resistor on the emitter of Q2.  On the Jax it looks like 8k2 on the SVC-1 I can't make it out.  The SVC-1 probably has 2SC828's in most of the positions.








-------------------
This one has 10k on the emitter of Q2 (but the collector resistor appears to be shown incorrectly as 4k7)

yeah rob ,verberola.

similar to the reslie tone but more primitive. the trem mode is awesome and could likely be implemented.
worst case, i can contact ari for better pics if anyone needs them.

it sounds a LOT different from a univibe... i dunno how to describe it other than thicker and syrupier.

I'm fairly certain it's the 100nF cap vs 220nF cap on the univibe.

Spreading the cap values is part of the sound of the univibe but it's not the way to get the deepest phasing.
If the caps were all the same value is would have the deepest phasing.  My guess is all 10nF's is about the "middle" however it might need some tweaking.   The lamp trimpot lets you trim this to some degree but it's best if the caps are sensible.

the trem mode is awesome and could likely be implemented.

Maybe it's got to do with the variable resistors being in the R1 position of a voltage divider instead of the R2 (grounded) position.   It's also got a cap in series with R2 position which is kind of unique as you might get a small mount of pitch-shifting.

Looking at the Verberola schematic and the front panel pic it's now clearer to me how the switching is done.  (The down position being tremolo).
