Two things..
A big (maybe 15") speaker and just a touch of reverb.
Heavy strings on your guitar.
I spent ages looking for that "Johnny Smith" tone and the answer was
staring me in the face. If you start out with featherlights strings you
end up with featherlight tone no matter what you do - you can`t get out
more than you put in.
Good luck

I have been playing guitar for about 7 years now and am currently
teaching lessons for the past 2. Im recently getting into jazz guitar
and looking to start a quartet but was wondering the best sounding
amp
for a deep jazz tone?
