Hi,

I'm having trouble with my Line 6 Low Down 300 Pro Bass Amplifier. My speakers work, there is an input signal as well detected in the amplifier, however, i do not hear any sound when i plug in my bass. once again, i've tested the speakers independently and they work but not when amplifier is plugged in to speaker. what problems are typically associated with this? Are there any tests I can perform? Is there a schematic available for this amplifier online or via email through line 6? Thanks for the help!
