Ibanez Acoustic Amplifier Model ACA15 Guitar Amp Powers up. This came new with my daughter’s Ibanez guitar from about 12 years ago. I never remember her using it. Has been in climate controlled storage in original box for past 10 years. I tried hooking it up to her guitar but suspect there is a connection problem at the guitar input. I rotated the plug and moved it inwards and outwards while strumming and would briefly hear sound through the amp. Will ship in original box as shown. Cables you see are included.
