Well I'm 43, been playing (out live) since I was 17, been playing since I was 14.
I have had more equiptment than most music stores, and still do!
I have found that what you speak of sounds great in the living room, but once you any any kind of volumn, your tone goes to sh!t period, if you want a decent live tone, you need rack gear, a head will not cut it. I have 4 sitting here that are proof!
Current set up is:
Digi-tech 2112 upgraded to the 2120 artist.
2 Rocktron 250 watt volicity amps,
into 2 4x12 Randall cabs, one loaded with celestion Red lable 70/80's the other loaded with scheffields.
This above is simple, I have had my experiance, carrying a Sun 120 watt all tube enforcer head, and about 20 pedals on a board, and the above cabs.
The tone is no ware near anything I have found in a rack set up.
I still currently play in an active band that is very well known, my information again comes from years of on the road experiance.
