I was just hanging around at my house and wanted to plug my guitar in to my digital piano which just so happens to be a roland kr377. My and one of my buddies who plays were gonna just play around and record and stuff. So i plugged the guitar in to the input (which the manual said was ok, in this exact input) and turned on my piano. I couldn't get a connection and the guitar wasn't playing through the speakers. I pulled the cord out and it made that sound from the speakers like when you pull it out of and amp, you know the "pop" sound. So I am trying to solve this dilemma. I know my guitar works through the PA system I use. So I don't think it is the guitar. I changed the battery in my preamp. Could it be a bad cord or something. Please help me diagnose my problem.

It could be the cord, try plugging a mic into the input, if the mic works...then you know it is the guitar/cord...if it works througha PA then you know its not the guitar.

I have a keyboard that I use as a amp sometimes for my electric...I have a cheap cord and sometimes it won't pick up on the keyboard.

You have three things and from what you said, its not the guitar...test the input with a mic and see if it is the input...

Need more info...

Sounds like you're putting a 1/4" Mono plug from your guitar into a stereo input. the mono plug won't match the conections in the stereo plug, until you pull it out and for a moment your guitar plug lines up with the ground and 1 hot connection. get a 14" mono-to-stereo adapter plug from radio shack $2.99 each. I just had the same thing hooking to a line in on my computer to run guitar through Cakewalk software.

That sounds like my problem, thank you sir!

uhh...I tried the Mono-Stereo Adapter. Still i have no connection. Could it be a Stereo-mono connection that i need?

[wilson78jr]

The adapter plug should have 2 lines of separating insulation. mono has one.

[CRG1400]

That is what i thought at first. Stereo has 2 lines doesn't it?
If that is the case i will just get a one that adapts that, right?

I doubt it's the stereo-mono thing.
Plugging a mono plug into a stereo jack simply grounds the right channel, leaving the left channel fine. You'd hear sound from only one speaker.

The adapter wilson describes will make the guitar come out of both speakers.


Remove the cable and the guitar from the equation by testing them elsewhere (ie through your guitar amp).

If thses work, try putting a walkman or other line-level signal into the keyboard's input. If still nothing, maybe your keyboard is buggered or there is some setting you need to change.

If you can heear your diskman, but not your guitar, and your guitar works, it's likely to be a matching problem. Borrow a DI box and go via that.
