Finally got to crank my SV today without an attenuator thru a 4x12. I brought it to band practice and first used it as a power amp. Works great as a power amp and is plenty loud enough with a hard hitting drummer and bass player. First thing I noticed was that as a power amp it sings (controlled feedback) better than my DSL. After practice was over I stayed and went direct in at full volume! Yeah, baby! I liked it best thru my Bogner 4x12 loaded in an X pattern with two Marshall G12 Vintage and two Greenbacks.
