Yes, the invective.MH has the same tight, articulate and aggressive high-gain character as the invective.120. Both were voiced by Misha Mansoor (Periphery) to meet his needs for a modern high-gain metal amp.
In small-format performance applications it may be suitable to play with a drummer, depending on the sensitivity of your speakers. When playing with a loud drummer and higher-wattage guitar and bass amps, additional sound reinforcement would be required.
With the 5W and 1W modes you will be able to experience power tube saturation at slightly lower volume levels. Reducing the wattage allows you to achieve "cranked amp" high-gain tones more easily and with more control.
Yes: you can use the direct output or USB to record whether you have the speaker turned off or not.
Extremely effective. MSDI eliminates the need for a speaker cabinet and mic, sending a studio-quality emulation of a miked 12-inch speaker direct to the sound system or interface.
Three 12AX7 preamp tubes and two EL84 power tubes.
T.S.I. alerts you to the status of your tubes and will let you know when a tube is nearing potential failure, so that you can replace it before your next gig. In the event that a tube fails, T.S.I. will automatically protect your amp's circuitry from potential damage.
