One of the first and premier devices for blending a piezo pickup with a microphone. 1/4" Line and XLR outs give you complete control as to what your acoustic instrument will sound like (guitar, bass, mandolin, banjo, fiddle..). Manufactured in the US in 1995, this piece has lived in a gator case for most of its life, hence no scratches or dents. Proprietary power supply included. This will be straight up, no reserve / no 'buy it now' auction. Good luck and !
