I have decided to purchase a compressor once again after having used the Keeley 2-knob unit for some time and being somewhat dissatisfied with it. I did find that it tended to color my sound and I ended up giving it to my son who loves it (hey, what's not to love - it was free!). I have been reading through many of the excellent threads here on TGP regarding compressors and have narrowed my search down to either the Barber Tone Press or the Diamond Compressor, both of which seem to get excellent reviews consistently. I have the Barber Silver LTD pedal and really love what it does in terms of a low-to-mid OD. I have no experience with Diamond products but their website is first-rate and their testimonials are strong. Any advice or suggestions would be very much appreciated. Thanks to all.
