I've heard that if a guitar sounds good un-plugged, it's gonna be a good sounding guitar when it's plugged in.
I think it's a good sign, if an electric sounds good unplugged, but it's not proof of a good/bad sounding guitar under other conditions, the attack/sustain characteristics can be very different plugged in, particulary on semi-hollow guitars, which always sound 'good' without an amp. Then again, most of the guitars that I think sound particularly good, sound that way without an amp too... As always, your mileage may vary. |
