[Harp-L] Clean & Warm Chromatic sound

[David Pearce]

I'm searching for a chromatic amplified sound that's clean & warm, but not crunchy.  I thought this tube preamp might be a good way to warm things up.

Vox also has some guitar amps that have tube preamps, that I thought be good for this as well.  Does anybody have any suggestions?
