Roland LPK-1, STK-1 and BAK-1 Kit

Description

In addition to the familiar Ibanez built, Roland-branded guitars like the G-303 and G-808, there were a number of guitars sold by third party manufacturers with Roland electronics. The guitars contained either the Roland LPK-1 or STK-1 kit. These kits were also available separately, designed to be installed by a professional technician. Installation is not an easy task, since installing the kits require extensive routing inside the body of the guitar. The GK-1 is a simple alternative that does not involve the extensive wood working, but the GK-1 saves on space by eliminating modulation control and other features.

Of the two kits, the most common one is the STK-1 kit. This kit was built around the later generation G-707 electronics card. The STK-1 is more popular because it is a smaller kit, and requires less space in the guitar to install. The STK-1 does not have the hex fuzz circuitry, and this saves a lot of space. As far as I can tell, the Gibson Les Paul model is the only guitar with hex fuzz. You can almost tell by visual inspection which kit is installed in a guitar. The STK-1 has a tightly spaced pattern of filter knob, resonance, mode and LFO switch typical of the Roland G-707. The LPK-1 kit has the controls spread in a wider pattern.

The bass version of this kit is the BAK-1. Like the STK-1, the electronics in the BAK-1 are taken from the last Roland guitar series, in this case the G-77 bass. I have never actually seen one of these kits, except in an ebay auction. I cannot find any additional information on the BAK-1.
