Introduction to the Roland G-505:

Guitar players who love the feel of a Fender guitar but wanted to explore synthesis were immediately taken with the Roland G-505. The G-505 has classic Fender lines with a satisfyingly chunky maple neck bolted to a lightweight ash body. The majority of the guitars shipped with traditional all maple necks and fretboard, but there was also a rosewood option. In addition to accessing the world of vintage 24-pin synthesis, the three single coil pickups did a great job of capturing the wide range of Fender strat sounds as well.

The fact that the G-505 is such a great representation of Fender stylings should come as no surprise to those aware of the history of the guitar's builder: the Fujigen Gakki factory had experience making quality Japanese Fender clones, and for years this same factory built Fender guitars for sale in the Japanese market.
Perhaps because there are such a wide range of after market products for Fender guitars, the G-505 has the distinction as the most modified vintage Roland guitar. While the original Roland tremolo works fine, and has the range and tuning stability of a typical Fender guitar, quite a few of the guitars you find for sale on ebay have the original tremolo system upgraded with a Kahler or Floyd Rose trem.

Pickup changes are also very common. Given that this guitar was sold in the eighties, it seems that many players were also tempted to replace the bridge pickup with humbucker. And a new neck on the G-505 was only four bolts away!
While the G-505 generally stays faithful to the Fender aesthetic, there is one interesting change: the passive volume and tone controls use 500K pots. Single coil pickups, like those in the G-505, are almost always wired with 250K pots. The 250K pots make for a warmer guitar tone, and tame some of the brightness associated with single coil pickups. But the G-505 shares the same electronics card design as the Roland G-303 and G-808, guitars with humbucking pickups. So the G-505 inherited 500K components in place of the traditional 250K parts.
I have mentioned this curiosity to G-505 players when working on their guitars, but most everyone has told me they love the sound of the G-505, and would not want to make any changes that might effect the tone. And this is a good idea, since like all the vintage Roland guitars, the master volume control is a dual 50K/500K pot, to control both active synthesizer level and passive guitar signal. This part is difficult to replace, though Warwick does include this part in their catalog.
