Ok, so I would like to get an overdrive or distortion pedal. My amp is an old solid-state Traynor TS-50. It is very nice clean, and has a luscious spring reverb tank in it, but the gain is very sterile and is only good for Shellac-esque screeching. I would like to get some very warm, relaxed, smoothly overdriven tones, as that would be better for the band that I am currently playing in. I play mostly rhythm. What pedal (under $100) would be best for what I want?
