PG's Chris Burgess is On Location in Nashville, TN for Summer NAMM '09 where he visits the Simple Amps booth. In this video segment, we get to hear from Simple Amps' Big Iron 34AV & 6LAV amps. The Big Iron 6VAV amp comes with 6V6 and the 34AV comes with EL34s, either 12AX7 or 12AU7 preamp tubes and runs hot at about 30 watts. The Big Iron 6VAV is built upon the same platform as its sister amp, the Big Iron 6VA, and the 34AV is very similar to the Big Iron 34A, the difference lies in the second "V," which stands for the added built-in Vibrato feature controlled by knobs on the front panel.
