I really like sound of my SWR LA12 amp. I especiall like the sound of the LA12 when I bypass the preamp section by using the MixIn power amp input. It is not the typical SWR sound (I know, because I played the Redhead, GrandPrix, SM500 and ST220 for a long time). So in fact it is the sound of the power amp and the 12" speaker. Does anyone know of a rig that sounds like that.
