JP-2C Channel 1 Volume Fluctuation

Post by lifeson2112 » Sun Jun 23, 2019 8:36 pm

Greetings! First post, and I'm sorry for no sappy introduction, but I have two young kids running around and barely have time to string two sentences together without being interrupted. I recently picked up a used JP-2C, and everything is great except that on Channel 2, the volume goes up every now and then, even to the point where when I turn the MV down on the amp, it doesn't work. I don't have the owners manual, and am just wondering if any users out there could assist in diagnosing this issue. On Channel 1 and 3, there is no problem.

I guess it's also worth mentioning the foot pedal cable is not working properly, either. Lot of 'blinking' lights and so forth.

Is this a customer service issue? I'm in the NYC area, so it's a ways away from LA.

Thanks for any input.
