Re: How can I fatten up my Tele?
You could also try out the SD pickup booster, which is made just to give low output single coil guitars a fatter sound.
I personally reccomend against the hotrails if you want your guitar to sound like a tele at all. The hotrails are extreme in every way, super high output (will easily distort your clean channel on low volumes), super crunch and great for metal, but not for anything resembling a single coil tone. It will also totally dwarf your neck single coil in terms of output.
