pre-distortion AND post-distortion EQ
Until just the last few years, Mesa Marks were the only amps that did this. A set of knobs to control EQ before distortion which lets you control the character of your distortion, and post-distortion EQ to control the overall equalization of the preamp. Then the Randall Satan came along and offered a two-band EQ and overall gain control, in addition to the standard post-gain tonestack. Now, the Wizard Hell Razor is the latest amp to offer this kind of control. The controls on that amp read "gain1, gain2, gain3, and saturation" but Gain 1 is pre-gain Treble, Gain 2 is pre-gain Bass, and Gain 3 and Saturation are overall gain controls at different places in the circuit. It's extremely useful and I don't know why it never caught on.
Negative Feedback knob
Global negative feedback control. If the amp is multi channel, give each channel a negative feedback control. It's a hugely useful and impactful control that shapes the entire voicing of the amp and dramatically increases the breadth of tones that can be dialed on it.
Frequency control of Presence and Depth
The Bogner Ecstasy Pandora has these controls for Presence and Depth. They're basically 3-position switches next to the Presence and Depth knobs that allow you to control where the frequencies affected by the Presence and Depth knobs begin. The Uber Ultra has this control on its Presence knob. It's a cool idea that can drastically expand the available tones in the amp.
Mid Range Frequency and Q Control
Dan had a great suggestion above and I agree with it. My own spin on the idea would be to have a single band of Parametric EQ for the Mids. In other words, give the Mid knob dedicated Frequency and Q knobs.
