I have a Mustang Fender V2 amp also, and if you want monitoring on the stage instead of the pedal board include the amp and the speaker.
Setting it up though would take some time but it really is not all that hard and with the Fender Fuse program (needs IE on the computer) the amp can be also set up on the computer via the USB cord attached to it. The 100 watt amp has the XLRs out of it, and the other amps I do not know but would have to look at them and all of it to know about them.

http://www.sweetwater.com/store/detail/Mustang3V2Although I usually recommend nothing to anyone because everyone is different, and not a tube amp and not as loud as a tube amp. Probably not as versatile as a pedal board, just like a list and turn to the appropriate number for the song (after it is all set up).
Some people say it is great, I say nothing because there is also a pedal (volume or effects) one can buy for it also, and don't you know, everything like this is easy to set up, until a person does it for real, and that takes reading the manual and working with the amp in the first place.
Good luck though, because I probably would sit at home and not play with that band.
(has something to do with a medical problem also - low energy, avoiding stress, etc.).

And this is another somewhat dumb post probably!
As said though it has XLR outputs (voume can be adjusted) to hook right up to a PA, house system, whatever it would hook up to, and also can record out of the headphones jack with full cabinet (I think if remembering correctly) emulation (neighbors not disturbed).
What you decide to do with or without the band though is up to you. I recommend nothing, nothing at all.
And the one place with the jam sessions is like that with miking everything, but that does not mean that they don't play without amps either - they do, and also the drums make noise also.
