Selling my Mesa M3 Carbine head Just like the M6 Carbine, if you were to leave the center VOICE knob on setting #2, which is the most popular setting due to it's common mid scoop tone that we like. That is where most amps live. This amp is 300w @ 4 ohms, and 165w @ 8ohms. The Mesa Walkabout is the same power rating, but this amp is WAY louder. This is a ridiculously loud 300w. Did I say it's loud ? Has a hifi tone. If you want an amp that lives in SWR / Eden land meets Ampeg if you dial it in right, then this amp is for you. If you keep the gain at 9 o'clock, you can get a real woody, upright tone. If you go to 3 o'clock, you can rock the house. Your cab will also determine your tone. All active EQ except for the passive mid control. Super FAST amp, as that is the Carbine's trademark. I JUST had this amp serviced by George the Genius at Mesa. It is LIKE NEW inside and good to go. I will throw in a 2 space rack to sweeten the pot even more. $599 shipped with 2 space rack !! $550 shipped without the rack !!
