If you play blues, why would you want a compressor? They rob you of the beauty of single coils - the dynamics. A compressor, to me, only really shines for a country player on a Tele. I think your money would be better spent on a good overdrive pedal, most of which compress somewhat as well as distort the signal. A pedal I have not seen mentioned yet is the Barber Tone Press, it has a blend knob that comes in handy for retaining some of your dynamics.
