The "Amp with the most Tubes?" thread by @Axis29 got me thinking.
What amp has the most external controls on it?
What amp has the least controls?
I'm counting every switch (toggle, rocker, rotary, button), slider and pot visible without going inside the amp. For amp, I'm including anything you plug a guitar (or bass) into that drives speakers or headphones.
My amp with the highest number of controls isn't too surprising: the Mesa Mark V with 58 controls.
My amp with the lowest number of controls is my Rockman X100 with 5 controls.
The mean average of controls on my amps is: 16.82
How about you?
