K&K Pure Sound Installation Information and some Photo comparison
I put up a webpage to help folks considering K&K systems. Basically, I like their systems that have external preamps. What that does is keep mods to the guitar to a bare minimum.
They offer two preamps for the two entry level units. One is the PURE PREAMP, it is a single channel unit and has external Bass, Mid, Treble trims and a main volume knob. Also comes with a beltclip.
The other is the TRINITY SYSTEM DUAL CHANNEL PREAMP, also with a beltclip. This unit controls the pickups plus an additional channel for the microphone. Depending on how you plug in the cords, you can select just the pickups, just the microphone, or a mix of both, or even two lines out with separate signal.
Anyway, if you are interested in checking K&K Pure Sound Systems out, you can start at my page. You will also find links to PDF files showing detailed installation, manuals, or diagrams.
