Nice concept, but such a thing would be not very functional.
I challenge anyone to do an entire gig with 4 buttons and no XLR output, but a Kemper Mini about the size of an HX Effects then with 8/6 buttons arranged on 2 rows, with the same display of the Kemper toaster, with the same 4 stomps in pre and 4 stomps in post, with 2 XLR outputs in addition to the 2 mains outputs, but with some restrictions like:
- no profiling
- no possibility of making it amplified
- not all the knobs of the head/rack versions, so it must be managed largely by a PC editor
- a number of saved rigs limited to 50-100 for example
at a listing price of 700-800 €, would cut off at the knees to all competitors.
Who loves all the physical buttons for adjustments on the fly (like me), who wants to make it amplified, who love his rack, who wants to keep a zillion of rigs and profiles on the machine, can still choose the toaster or the rack.
By the way, not everyone is interested in profiling his pedals and amps, and moreover not everyone has the knowledge and gear (mics, audio card, preamps) required to perform a good profile of his rig. For most users, the Kemper is a convenient way to have access to a list of amplifiers they could never afford like Cornford, Hamstead, Hiwatt, Dumble, Mesa, and so on...
The fact is that market no longer thrives towards the heads and racks as 10-15 years ago, but towards the desktop minipedalboards (Fractal FM3, HX Stomp, HX Effects, POD Go, Hotone Ampero, Mooer GE200, Quad Cortex ). A small pedalboard for live gigs with 4-6-8 footswitches, that can be used as a desktop practice/recording amp also.
