How about just the Kabinet DSP with parameter selection in a pedal so you could use the Kabinet
with a tube amp? I think this would be a great setup and would sell a lot more Kemper Kabinets.
The pedal would go into a loop between the pre and power sections of the tube amp.
This would also work with any other amp modeler or amp sim. Just place the pedal after
the modeler or amp sim and add an inline power amp. Same setup as with a Kemper.
