I have an Elf as well.
This is 500w if used with two 8 ohm/ one 4 ohm cabs, Elf is 200w. So it has more headroom.
Feature wise theres no comparison. This is Jaguar, the Elf is Mini Cooper.
The Elf has its own sound, astounding for its size; the MiniMAX can give you many variations as well. The TT boost, punch, midshift and bright buttons are all toneshaping options.
