Using Valvecaster/Vibracaster as a preamp...

[Brossman]

I don't like the preamp in my Musicman RD112. It's a hybrid amp, with SS pre- and twin 6L6 output tubes.  I'm not particularly pleased by any of the tones I get from turning the Pregain up. (I know, call me crazy...)

Is it possible to cut out this SS pre- and splice in the Valve/Vibracaster circuit?  Or would there be a more appropriate 'valve' circuit that I can use?

Sure. Guitar > valvecaster > effects return. Depending on how good the fx loop is, it my sound good. I ran a Mesa quad preamp like that into my engl screamer and it sounded fabulous. On my old amp though, ashdown fallen angel, it sounded balls.
