A very small Zoom MS-50G would get me through a gig.
I picked up a Vox Tonelab LE for that purpose, then an Amplifire. However, I was spoiled and got rid of the Amplifire and picked up a second KPA as backup. I still have the Tonelab, and the acoustic guitarist at church uses it...
I don't and every night I set up the KPA I think to myself ' I must organise a backup of some sort ' ....
thanks for reminding me ( again ! )
I have an small AMT-SS20 pedal in the gig bag as my backup. Has a cab emulated out that actually sounds not horrible and would get me buy in a pinch. 3 separate channels (clean/OD/Lead). I did change the 12AX7 out to something a little softer as the lead channel was way too much gain for me - but nows it's basically the perfect compact backup. Havnt actually needed it live as yet - but it puts my mind at ease that I have an options if my main rig ever decided to play up 
My backup:
Telecaster, Vox Tonelab ST and Behringer 205D as personal Monitor
Orange Dark Terror
Blackstar HT Dual pedal.
I have usable guitar patches setup in my Roland GR55 as an emergency backup for my KPA. But also carry a Digitech RP500 in case my whole regular setup goes down

Did you put in a 7025? I swapped those for the 12AX7 in my old JMP-1 and also in a Hughes and Kettner Switchblade - that tube does a very good job of softening the character of preamp distortion.
I bring a Marshall head and 4x12 cabinet to every gig for backup. 
No, actually I bring a POD 2. I would either reach over to switch between clean and dirty settings on it or keep it on a dirty setting and use the guitar's volume to clean up.
Peavey Classic 20 mini head direct to FOH and M13 effects.
Always have a Zoom G3 in the trunk of my car.
I use a Sansamp Liverpool as a backup. I've never needed to use it though.
I'm using a Zoom G3x for my acoustic guitar, and I have a few electric guitar patches on it too, just in case...
And my KPA has a backup acoustic performance too

I actually ended up using a JAN 5751 tube. I have a drawer full of various tubes and after spending an afternoon trying them all out, this one just got me closest to where I wanted to be. The AMT SS-20 is really a high gain monster on the OD and lead channels, but thats not what I need as a backup. The 5751's lower gain totally tamed that and added a really nice "big amp OD low end" thump to the sound. I'll admit, I do kinda miss tinkering and trying out different tubes in amps at times (kind of a nerd like that), but now I just turn the Kempers browse knob, and basically get the same satisfaction. Really do love the KPA!
I live dangerously and don't have any backup amp. Never have and for the 3 years I've owned the KPA it's never let me down.
I know, I'm crazy but ya gotta be crazy sometimes 
A Rocktron Chameleon, that I've used before I bought the Kemper.

Wow I remember them, I had one of them about 15 years ago, the green face one
