I've been reading a lot here, and I'm very interested to see people lambasting "enhance" or "contour" circuits. I have one on my GK400RB-III head (a knob) and on my GK200MB combo (a button). The amps sounds so good with them off, and you turn them on, and the tone leaves. Instead, you get this awful scooped sound that is totally without use, except in the bedroom for practice. Why are manufacturers still putting these things on amps? Who uses them? And why can't people that use these things just do the same thing with eq, and maybe make a frequency swtich be standard instead of the mid-cut only enhance? That way, those that like that effect could get it by cutting mids at 250hz or wherever enhance is generally centered, and those that actually like mids could make use of the extra control.
