I would keep the Ueber and sell 20th, 101B and Shiva and get a Shiva 20th instead. I would sell one of the two Wizards and get a good old Superlead Marshall.
Just a hypothetic situation
I made a list of amps that I thought would be most useful in a studio
I thought some people would have said to add a 5150/6505
Fender (Deluxe Reverb?) and AC30 seem the most glaring omissions
