An engineer friend, who has achieved "legendary" status due to his work at Muscle Shoals Sound in its heyday, asked me to come jam with some of his friends. (They apparantly get together once a year for a jam). One flew in from Florida. These guys were all much older than me. Awesome musicians. There were 5 vintage tube amps set up when I walked in, and I mean classics, one from the 60's. I felt odd walking in ith the AxeFX2, I'll admit. I set up a QSC K10, my MFC and the Axe fx. I received some strange looks. However, after hearing it, they were blown away. It definitely held it own. I used the Vox AC30 and JTm 45 most of the night. Awesome product. Now I just have to get volume between patches set right.
