Glad someone likes it. It was my first try at doing a website but it turned out OK. Most of the pedals are mine except for the Juggernaut which I don't own one yet and the R2DU but I did aquire one of those after I put the site up but never changed the pic, and of course the pic from the 1st 12 Rats made.

I'm not sure why ProCO started using a Log taper pot on the Filter control but the first issues that use a Linear taper sound much better because you have a lot more usable range.

I'm always up for suggestions or additions.

hey dosmun,

try linking with other RAT sites. Especially those with Schemos... 8)

here are a few that I found while drinking coffee & googling.....

http://happybob.com/rstrand/rat/rat_versions.htm (good links for schemos AND history)

:roll:

That schematic should be forbidden. Vanish off the surface of the planet. Be ritually burned or whatever. I'll leave it to RG to tell wether he has ever seen a RAT with a FET input buffer*. I haven't ever and I've seen a lot of RAT's over the last couple of years. However the positive feedback in this schematic (the gainn determining components should be connected to pin 2 and not pin 3 of the opamp) is the major definite error.


* Having seen newer versions by RG's hand make me suspect he knows :wink:
Sorry. Plain out of planes.

Then you should also blame Jack Orman. He did the corrections. :shock: :hmmm:

There are definitely some wrong schems out there, but I think the input buffer thing may be correct. I have a late 80's "LED in A" Rat with TWO transistors + IC, leading me to believe it has an added input buffer. The earlier non-LED Rats had ONE transistor and were better sounding IMO.

Hows about guts ?

....because maybe the second transistor is used for LED-switching an not as an input buffer ? :roll:
