My amp just died and I need something to plug my guitar into.

I have and old CASIO CT-700 tone bank keyboard witch has 4 ports:

  • MIDI in
  • MIDI out
  • phones/output
  • sustain

Is it possible?


Fit a Roland GK3 to your guitar and you can play the keyboard tones via your guitar using Midi.

I realise that's not what you want to achieve, but it's cool none the less!


No, you cannot plug your guitar in this particular keyboard. The Phones jack is a stereo output for headphones, the sustain connector is for a pedal/controller and the midi connectors are for midi control signals to and from an audio interface of some description.

It is possible to connect guitars to some keyboards, as I have utilized this functionality in the past, but they tend to be very expensive keyboards and you're not really meant to do it.

You could however invest in an audio interface and plug your guitar into your PC, then use a guitar effects/amp simulation or modeling program. That or invest in a new amplifier.

    To add to Kyle's idea of plugging it into the computer, I believe you could plug it into the microphone jack of the computer. So you may already have one built in. Depending on plug size you might need a 1/4 inch to 3.5 mm adapter. – jcadcell Jun 28 '16 at 14:12
  • @jcadcell true, but the sound quality will be horrible. – Kyle Jun 28 '16 at 20:06

    If you have an iPhone, or an iPad, or a Mac, there are interfaces that are not so expensive, like the iRig, see ikmultimedia.com/products/cat-view.php?C=interfaces – MaTECmatica Jun 28 '16 at 20:13
  • If you buy an audio interface, you can use a virtual amp and have excellent quality (with effects, distortions and everything) just by plugging your guitar straight to the audio interface. another thing you can do is use a pedalbord and then plug to the computers microphone (red input) or the blue input (if there is such). The quality will be slightly increased from just plugging to your pc – papakias Jun 29 '16 at 9:08
