I've been playing around with a Concert Lead for a couple of weeks now, and I'm not sure if I wholeheartedly agree. I have a red knob version, plugged into a 4ohm 4x10 ampeg cab, and it's not quite loud enough in band practice. The volume jump is really great from like 2 to 3, but sorta evens out after that. I really like the sound on the A, D and G strings, but the low E gets way more solid rumble than tone + rumble. I don't know, maybe I'm just not dialing in the right sound, would appreciate any help anyone's willing to offer. Using it for a fast hardcore band, if that's any help.
For guitar it's amazing, tho.
