The 15" driver in the 200c and the 115 cab really sounds great. Both have a compression tweeter that is missing from the 100c. My rhythm guitar sounds good enough through my 200c, that I no longer use my VOX AC4 practice amp, or my BA-108 for that matter.
One thing you can do with the 40c on up is daisy-chain 2 of them via FX Send (amp 1) to FX Return (amp 2 as speaker cab). Works great.
I also prefer the 12" driver in the 100 to the 10" drivers used in the 500, 800 and 210.
Bonus Fender Rumble v3 tip: You can use the OD circuit as a mute. Turn both knobs fully CCW (off). Switch on the OD circuit via footswitch. Instant MUTE!
Rumble on!
