Can I assume you have it connected to an amplifier?

Maybe it needs a reset. From the manual:

"In order to clear any bugs (software malfunctions) that can occur in 
the memory during battery replacement, be sure to press the P button 
with a pointed object (1) after you have inserted batteries for the 
first time, and (2) after you have inserted new batteries when the 
time that has elapsed since removal of the old batteries is more than 
10 minutes. Pressing the P button causes the 16 sounds set in the 
internal memory before shipment to be recalled. At the same time, any 
new tones you have set in the internal memory will be cancelled, so 
please be careful.

Be sure to press the P button when power is turned ON, otherwise it 
will have no effect."  

(the P button is on the bottom, near the battery compartment.)
