Sure, Bruce Zinky (who designed the Prosonic) did not have any direct input on the Supersonic.
When I say 'based on' I simply mean they are similar design- cascading gain stage drive channel and a similar config.

I have the original 10" Celestions in the combo and a choice of 5 difference cabs for the head- I mostly use a Marshall 4x12 with V30's or a 2x12 with G75's.
The 10" Celestions are plenty loud and full for most situations though.

Both have been modded quite a bit.
First the prosonic has a fault that results in a loud 'thunk' when you switch channels. It is a design flaw but it was fixed.
I also have modded the reverb to be less wet and noisy.
The drive channel is tighter and more percussive.

Lastly the clean channel has been worked on to be less gainy.

I have links to the schematics for some of the mods here:
