a busbar (also spelled bus bar, or sometimes as buss bar or bussbar
 
Hitherto I've always thought a bus was just that, a bus. (see this post)
And a buss was what I moved power about with in a circuit,
or in the case of a mixing board routed tracks or sub b̶u̶s̶s̶e̶s̶  buses to.
I stand corrected, and henceforth I shall refer to (but prefer not to ride) the bus.
Which reminds me, I did once ride the bus, a Greyhound in fact, from Albuquerque to Tucumcari,
but that's another story...
or not!

Tehachapi to Tonapah?

I've been on a bus that had a bar before. 
(Ok, it was a trashcan filled with beer on its way to Mammoth Mountain for a ski trip, but that should count, ya?)

There is a loop bus here that will take you to different bars on the weekend.
There was also one that they were drinking beer on also and listening to music while going around to different bars, I guess another loop bus.
 

So loop your bus.

If I had room is the chassis, that would be "Standard Equipment" on ALL my amps!
