I was about to say that The BM sound works well with practically any treble-booster in front of the normal-channel of a Vox and so does the KPA emulation of that chain.
Having said that, though I like the TB of the Kemper, I still prefer my BSM RM pedal because of the different flavour.
I think we once swapped mails and you sent me a testfile that I put through that thing and sent back the result. Any chance of seeing the outcome of that in the KPA?
I just wanted to take a look what it does frequency-wise. at best it could become a eq preset.
