K&K's Pure Mini pickup is our bestselling pickup, by quite some margin. But as good as that pickup is, folks occasionally find they want the added bonus of the mic and blending preamp you find in the standard Trinity Pro System.
But rather than make you rip out your Pure Mini and start from scratch, K&K offers this upgrade kit. It works with either the Pure Mini or Pure Classic, and it includes the mic, internal wiring, and external belt clip blending preamp. You do have to solder your existing pickup to this new rig, but it's a relatively painless way to upgrade to the Trinity Pro system if that's what you're looking to do.
