Neovibe R42, R43 questions...

[Greg]

I've got an older Neovibe that I built using RG's board kit from around 1998 and I'd like to do the R42, R43 mod but I have nothing that tells me exactly which resistors these are. My pcb isn't labeled and the documentation that came w/ the kit doesn't show it and there are about 16 4.7k's on this thing. Can anyone help me to pinpoint which resisitors we're talking about here specifically?
Thanks,
Greg

Tell me what the R42/R43 mod is and I can tell you where to look. I know that layout fairly well

Hey RG,
I actually figured it out. The mod calls for replacing two 4.7ks w/ 2.4k's to increase the top speed. I dug a little more in your "Technology of the Univibe" article and found a blurb about the two 4.7k's leading out to the dual gang pot as being responsible for the top end speed. From there, I just looked at the pcb and found the wires leading out to the pot and lo and behold, there were the two 4.7k's along w/ the 220k ohm resistors and I had it. Seems to have worked pretty good. I'll see how I like it over the next few gigs.
In case nobody's said it in awhile, you are an amazing resource on the internet for all this stuff. You were instrumental in what I was able to accomplish w/ building my own pedals and fixing a bunch of stuff I had that didn't work anymore. I've been out of the DIY pedal thing for a few years but have since gotten into other things like refurbishing old tube AM radios and tube hifi gear. Managed to put together a nice Dynaco stereo for myself. All of this partly based on the confidence you and some of the others from the late 90's Ampage days have given me in diving into some of this stuff. Not to mention, during that time, I had lost my dad and was back home w/ my mom in full blown depression and getting on the computer and finding some solace in the DIY effects forums really helped me through that tough time in my life. Thanks for that!
Anyway, the Neovibe has been gigging strong for the past 5 or 6 years and hasn't left my pedalboard! Have there been any new revisions or anything that I should know about?
Thanks for the quick reply!

You've got that right! I built a vibe in early 1996, & R.G. stepped me though quite a few problems and modifications until it came out right. I have gigged with it a lot since then, although now, not as much as between 1997-2000, but it's still on my pedal board & sounds great! I now have been jamming & recording more often with some guys, & it's in heavy use again.

Thanks guys! I appreciate the feedback, and I'm glad that beast is still working for you.

I've thought about this a couple of times. I couldn't start small with an effects layout, could I. Nooooo, I had to go attack the Univibe as my first public offering.  :shock:

It was a good teaching vehicle for me.

Again, glad they're working for you.
