get a strat: listen to albert collins for 6 months. (or is that buddy guy?). use bridge pickup.
funk, no horns: get a strat. listen to blood sugar sex magic for 6 months. use position 1.
funk, with horns: get a strat. or a tele or a semi-hollowbody. listen to tower of power for six months.
for me, i'd get a wah pedal. none of that auto-wah/touch-wah stuff. mas matututo kang mag-express ng nota. (although a synth-wah/envelope filter for funk might be very useful).
