Some say in a Fender 5e3 or 6G3 Deluxe the tone control pot is more sophisticated than the whole tone stack in a BF Deluxe amp.
The 5e3 or 6g3 with their single tone pot (per channel in the 6g3) are more midrangey and that results in a crunchier sound.
The "scooped" mid sound of a BF Deluxe keeps it cleaner.
With the dual channel 6g3 you can dial in some bass when turning up the volume pot of the unused channel. Wouldn't work with a singel channel amp, though.
So many guitarists believe in the 5e3 with it's single tone control.
I believe you can find "your" sound even with a single tone knob, depending what your basic idea is.
If you don't like the midrangey sound you better go for the Kit with the TMB tone stack.
Provided that they are wired the way a Fender BF is.
