"Here's a package deal that will get you playing a modern 13 pin guitar synthesizer controller with a vintage Roland GR-300 Guitar Synthesizer module.

** This system is not recommended for use with GODIN 13 pin guitars ** See below for more information.

The winning bidder will receive the following:

1) One of Roland GR-300 Synthesizer Module with upgraded capacitors and a DB25 pin input. Unit tested by none other than Wayne Joness in January 2013.

2) One of RC-1324-VR 13 to DB25 pin converter. Built by Wayne Joness in January 2013 for myself.

3) One of DB25 pin cable to connect the RC-1324-VR to the GR-300

The overall condition of everything is excellent for the GR-300 and near mint for the RC-1324-VR. Everything is in proper working condition.

You can get more information on the RC-1324-VR at Wayne's site: http://www.joness.com/gr300/RC13.htm

Please Note: The GR-300's input has been changed from one that fits the traditional 24 pin cable to a DB25 style input, allowing for use of inexpensive and shielded replacement cables such as those made by Belkin, as opposed to the expensive and non-shielded proprietary Roland 24 pin cables. What this means though, is that if you plan to ALSO use this system with a viintage 24 pin guitar controller like a G-505 or G-202 etc...., you will either need to make a 24 pin to DB25 pin cable (Wayne can make you one....) or, you can modify and upgrade the controller itself to a DB25 pin output and solve your Roland cable issues forever.

The GR-300 unit was tested by Wayne Joness in January 2013. Here is what Wayne had to say:

'Hello Keith!

So...I am happy to report your GR-300 passed all the tests with flying colors.

I have removed the bottom panel, and I can tell you that your unit is a "version C" meaning the final revision of the circuit board. This is a good thing.

I checked the power supply, and your unit does have the problematic blue tantalum capacitors in place:

I did not mention this originally when you asked about sending me your unit, but I would like to propose that I replace the blue tantalum capacitors with modern electrolytic capacitors as outlined on the website. This will protect your GR-300 from future failures.'

I agreed to the capacitor upgrade of course! So the future owner has a fully bench tested AND upgraded/protected GR-300 to boot!"
