Well, it's a tube amp.
I really meant something fully digital, so it could be updated, so you could pre-select different models (into, say, 3 slots per channel, controlled by a 3 way switch), etc.
Well, imagine you'd be able to preselect your FX from a great palette, such as what can be found in the HX series or such. Just what would be exposed would always be just 3-4 knobs with the most relevant parameters working WYSIWYG style (and again with another 3 way toggle to select different models quickly).
Seriously, a 4 channel amp with individual boost (gain and level) per channel, 2 mod FX, 2 delays and one reverb would very likely take me through each and every gig I could ever imagine (unless it's some deep soundscapery thing required, but for those puposes you'd be using other things anyway).
In the end, you'd have 100% analog style "editing" (unless you wanted to go deeper and do custom things - but even in that case, once it comes to playing, everything would be 100% analog style) with all the advances of digital, such as being able to go direct, play at any volume, use the same thing for recording, have independent levels for FOH and your monitor/cab, etc.
Such an amp could as well be used for literally any gig, as the editing software would allow you to preload each channel with whatever the style you're into required.
Really, in the end it'd be a pretty capable modeler, just that it could be operated as quickly as an all analog setup and would allow people not into *any* kind of menu diving to use the thing as well. Do a careful factory preselection of amps (3 amps per each channel) and you might find some folks never even wanting to touch the accompanying editor.
Obviously, there should be an accompanying floor controller that should be dead easy to configure on the unit (allowing you to switch to any status on any switch but also allowing for a hybrid or plain manual switching mode). Should have a dual function pedal option as well (typically wah/volume) so you wouldn't need to have any sound running off the board and the board should be mountable to the back of the top or combo, so your entire rig would really be a one-single-device affair (unless you wanted an external cab of your choice).
I'm absolutely not sure whether such a thing would be a success, but so far we simply can't know because nothing even remotely like it exists.
Realistically, *if* such a thing existed, for, say, 1.5-2k, it could even be an almost instant buy for me. It'd be the perfect best-of-both-worlds setup for my needs.
A company such as, say, Line 6 could develop such a thing with pretty much zero R&D cost as all the technology does already exist in their current products. It'd just be a vastly different exposure.
