If price is no issue and perfection your middle name I can fit a Beyma 12P80ND. It has even more sensitivity, sub-lows, and is lightweight.
A touring bassplayer needs a good flightcase. I can have a custom flightcase built for you anyway you want it.
If you want to combine JM’s, but your amp has only 1 output, I can install link connectors in the cabs so you can daisy-chain them and you don’t have to fool around with Y-cables.
The frontpanel color is your personal choice. Black is standard.
