I have had problems getting good stage tone(s) when playing live with my JTV-69 thru a POD HD 500. I've tried a Laney solid state acoustic amp, a Koch tube amp (both run out of the POD and into the effects return), and a full-range Carvin powered PA speaker. I play covers, so I use a variety of tones, including acoustic ones. What do you all think is the best way to amplify this rig? The DT series amps seem more geared towards electric tones.
