Today's useful links are real beauties, , I thought of Jim's quest for the perfect tone when I heard this in action.
Voxengo Tube Amp adds a lovely valve tone that can be pushed to crunch if needed, just like the real deal
I really liked it used in a chain with a dash of tremolo in front, and some classic reverb after. If you want to get raunchy it sounds great paired with the 'Tube Screamer' VST that I came across
here along with more classic effects sims, and even Fender Twin and Marshall JCM 900 amp sims!
They might not look too pretty, but they sound excellent. If your recording program can host VST's then I must really urge you to try these.

Mick
