So far I have tried the following combos with the kemper with mixed results
Fender Mustang III Mk 1 - Sounded super fizzy
Line 6 Spider Valve Mk 1 - Sounded great but volume control is unstable and power valves died
I like using a combo because of the compact size and of course the built in power amp. Also you've got a backup if the kemper ever went pop mid practise/show.
Has anyone tried any other alternatives such as a fender champion 100 or a spider jam 75? Any other suggestions?
