Neovibe vs. commercially available vibe units. Thoughts?

[plankspank]

does the neovibe have the same wimpy output as the original?

The beauty of the Neovibe is that you can tweak it to equal the sound of a real univibe without all the negatives of the original unit ( like a crappy 1/2 wave power supply , low sound output, not true bypass, ect..)
     You can get more output by adjusting the R8 / R9 emitter pair resistors on the Q3 input stage. or you can add a JFET input buffer right before the R2 input resistor. I did both and the extra output really kicks the front end of my NMV Marshall for some nice crunch if I want it.... Jimi would be pleased..

SteveB's clips of the neovibe and an Easyvibe can be found here: www.mrdwab.com/john/soundclipspage.html
These are the best clips of both of them that I have heard.
If you don't like these clips then it's safe to say that you don't like the univibe sound.

What I hear in those clips is that the EZ Vibe is so close to the Neo-Vibe sound that the difference in effort would offer diminishing returns for me. I've had an EZ Vibe PCB lying around for years. I need to get busy and build that thing. It sounds awesome!

And come on John- Can't you do a better job explaining all those clips you host? How about listing resistor and cap tolerances of all the amps you use as well as telling us the string gauge, wood density, and the pickup resistance of the guitars? Come on man! How do you expect people hanging out on free forums to make the proper choice of what free information to use to build their dream nirvana pedal if you can't properly explain the free clips you host? What's wrong with you anyway?

Seriously, John and Steve. Those clips are really awesome. They are the best sounding EZ Vibe clips I've heard. Thanks for putting in the effort to make and host them.

you could save the world with that kind of information

Thanks for the nod!

Steve B did a good job coaxing some nice sounds from the EZ vibe. I was suprised honestly.
In person I believe the Neo has much more oomph and complexity, a richer and more organic sound.

The way the uni/neo's phase sounds with that lopsided/warble is much more desirable to my ears.
The EZ vibe seems like more of a straight phase as opposed to the uni/Neo's throbing offset phase which is hard to describe, but you can feel it when you play it. The Ez seemed sterile or anemic even after a few tweaks.

I don't think there is any more effort in volved in building the Neo vs the EZ vibe. You just need a transformer and to try some LDRs.
Redhouse has outlined several models in previous threads. Just search for those and you'll get something that works well.
