Alright so I noticed that on some Fender amps there are 2 inputs....does that mean that you could have to insturments on one amp?

Fender FM 212R

Fender '65 Princeton Reverb
Epiphone Archtop Dot
Ibanez RG120
Peavey ValveKing 112
Dunlop Crybaby
Boss Distortion Ds-1
MXR Carbon Copy
Rocktron Banshee Talk box
You can, but it sounds like ass.

What many people do with the all-tube amps is jumper the channels.
It could be useful in an instruction environment where a teacher and student take turns but to imgooley's point playing at the same time would sound all that great.

My Valveking has 2 inputs but the second is a toned down Class A type affect. Not sure how it works actually. Different characteristics for sure.

Are you looking for a new amp Drmmrb?
