Bassists the world over responded overnight to the new clarity, on-demand attack and crystal-clear definition of the M6's Trans-Class™ all-tube preamp and MOSFET power. They love that it's easy to dial and yet offers all the versatility they need via the power of the rotary VOICE feature. The next step in the evolution of this dynamo was obvious. Add substantially more power and endow the preamp with a full set of studio-quality EQ and dynamic features. Now the M9 Carbine escalates the race with a mighty 600 watts (into 4 ohms) of Trans-Class™ power and yet still harnesses all that energy within 2 rack spaces.
