the 1959 slp has an awesome sound. personally this is what i would go with but i dont play in a metal band either. Pete Townshend (from The Who) used and still uses this head. Warren Haynes (The allman bros.) uses this head. very bright clean highs and earth shaking lows.

if you play in a hard rock/metal band i would use a mesa boogie dual rectifier. save your sheckles though because they are pricey. The guitarist from tool uses the dual rectifier over the triple. yes you lose a channel by going with the dual but the sound is so much better.

the difference is the triple rectifier is 3 channels and the dual rectifier is 2 channels. the dual sounds better

go for the mesa it has the power the best distortion ever and if your style in music changes so can it for more in or if you just want to talk guitar gear. Tom [email protected]

You know those are three VERY different amplifiers? I too am looking at a prosonic vs. MESA. I think one of the things to consider is that the prosonic has 2×10 speakers. Also both the channels share an EQ so you have to have a setting that works with both your clean and distortion sound. It does have a very good sound though. The rectos are much heavier more compressed sounding. They have separate EQ’s and many more bells and whistles. However, they are also more expensive. Bottom line: play them, trust your ears. But consider what you want to do with your sound, and if you need all the options, or whether you just want a straightforward sound.
