Hi Listener,

Those 1/4-inch phone adapters and jacks are notoriously unreliable. Try cleaning the contacts and wiggling the connector around if you are using the adapter. I know one of my stereo mini-plug to 1/4-inch phone plugs is always intermittent unless I clean the plugs and firmly insert it.
