How big of a difference do amps make?

Listening to a live jazz quartet(alto sax,B3 Hammond,guitar and drums) last night there must have been a lot of 2nd and low order harmonics present in that club. Those instruments were quite warm,full tone and rich. One thing they were`nt was lean,thin, washed out or bright. So I guess the instruments were`nt producing those odd and higher order harmonics. If that`s the explanation.The tone of the alto and guitar were the antithesis of clinical,lean and bright last night.

Yes- naturally, real instruments have sounds composed of both even and odd-ordered harmonics :)

Well, based on your earlier explanation on how the 2 types differ,even order was clearly in charge of the show last night.

Atmosphere,
Thanks for your info on the paradigms and harmonics. Interesting.
