I would NOT like to have an allrounder-amp. I need an amp who does one sound really great and not a dozen close to great. In addition I don't want to deal with a shitloads of knobs and the weight of components I never use, above all I don't want to pay for those unneeded extras. My dream amp would be one-channel with pre- and master-gain, 3 band eq + presence & resonance (like the 5150).
I think it doesn't make much sense to build an allrounder amp where every circuit and gain stage is exclusive to its channel.
What I would like as uncommon extras:
- knobs that can be fixed (like Ibanez "Tone-Lok") so you don't accidently lose your settings.
- the weight of the components should be tared (unlike old Marshalls where one side is the heavy one)
- no vent slots on the upper side, just in the back
- top of the amp should be flat with the handle buried
- 2x4ohm, 2x8ohm and 2x16ohm jacks in the back
- input jack in the back
- all knobs must be able to be read even from a distance (like 5150 - unlike rectifier)
- cool looks, of course!
I'd love to see the tubes glowing inside
