Well, knappo, I don't know if this will help. I use a Crate Acoustic 60w amp with DSP(digital signal processing), and lately I have been playing harp through the "vocal" input, with max reverb and distortion. This gives the harp sound a kind of fat, tremolo weight, with a trailing echo. For heavy blues and rock playing this works pretty well, but it might be too much for acoustic type blues or straight harp styles. I find this amp makes an excellent harp amp as well as a versatile guitar amp, and eliminates the need for many basic pedal-type processors.
