I'm getting a used 2-knob Keeley compressor with internal trim pots at a good price (apparently from what I've read, the earlier models didn't have the internal pots). I've always been curious about this pedal, partly because of it's reputation and partly because it's one of those things so many people have had and seem to have put to good use, especially country Tele players, so it's always been on my radar. It seems to make sense to use a comp with single coils, at least to my mind theoretically speaking, since IMO humbuckers compress enough on their own, but my knowledge about compressors is quite limited thus far. I've only used a compressor briefly - I got a cheapie Behringer at a trade show for free and it was always too "squishy" for me. Maybe I didn't understand how to use the settings, but there seemed to be no point on the attack knob that didn't attenuate the the initial signal noticeably, in a bad way. I read 2 posts from a TGP member on 2 different Keeley comp threads that implied that people use compressors (like the Keeley) to make up for their amps' shortcomings. What he wrote was that thought his amp was so good that he didn't need one (except that his amp OR the Keeley was out being repaired at the time he wrote each of the posts so it wasn't a conclusive statement). I hope that I don't use it to make up for my amps' shortcomings and wind up ignoring the fact that one or all of my amps might need work by my tech, which they proabably do (new tubes, speakers, tweaking, etc.). I've been holding out on that stuff because of money - but instead I buy a new pedal (somewhat impulsively)! I hope this wasn't an unwise choice.
