i dont mind if they're rails or stacks and yeah i looked at the tone zone and it had the right stuff, but ive also thought that SD cool rails would be a good contrast to my hots.
i shouldn't worry about them being to bassy, i like bass, and the jag cleans up nicely as we all know.
when i say splits i just mean putting a pull push in place of the volume knob and shutting off probably the outer rail.
