From the type of music he plays, if he isn't using any effect pedals etc. then I would recommend a dual channel.
Wattage wise, very dependent on the amp and its break up profile and the type of music being played.
Since you want American ... a classic American route to go would be a Marshall...
Let's see ...

What do you feel is lacking in your sound at the lower settings?
Not to be evil but pedals, EQ and even post production can fix a lot of 'balance' in the sound output.
What can't be replaced is the 'feel' that happens when you are moving a good amount of 'air volume'
or the direct sounds.
Princeton is great, however a someone mentioned, major dislike on the 10".
I got myself a custom built amp at the cost of a princeton that is based on the princeton circuit,
is a 1x12 combo and is twice the power and features a half power switch.
I started out with an acoustic that had a terrible setup, only later on did I learn about luthiers and setups ... so my early problem on electrics was pushing strings down way too hard.
I'll take an easy to play any time though.
Oh yes how can I forget, the reverb! Not sure what he did with that, but the Brentwood had 'godly' reverb.
Brentwood I believe had a three knob reverb. (been too long)
Do note that not all his stuff comes with it, I think the Gibb Droll standard doesn't have it?
Had two Holland amps, a 2x12 Brentwood and something that was a bit of a one off.
Don't think I've ever heard a better clean than the 2x12 Brentwood.
These amps are ... really loud ... and heavy.
I never looked inside the guts, but I think they are superb.
Is this a good value, sorry not sure...
