The M-Pulse 600™
Simul-State™ Bass Amplifier

Establishing a new paradigm of bass performance, the M-Pulse™ line combines the best of musical old-world tube technology with modern high-power portability. Available in a 600 watt rack version, this handmade beauty sports our soulful sounding Simul-State™ tube driven MOSFET power. This is our proprietary hybrid technology that uses vacuum tubes from the Input jack right up to, and including, the driver for the custom MOSFETs. And this dynamic team produces stunning musical power.

An all-new tube pre-amp feeds the rotary tone controls starting with active Bass and Treble and including a warm passive Mid --this is your foundation. From there, craft your own seductive world of bass using the five-band parametric EQ that lets you roam for tone unbridled between 30 Hz and 12kHz. Dynamics are manipulated via an all-new on-board Compressor featuring Threshold and Ratio controls.

Our proprietary Solo™ function provides a second master volume for a footswitchable boost when it’s spot light time. Or use Solo as compensation for extreme EQ or Compressor settings.

M-Pulse amplifiers provide a toneful balanced Direct Out featuring a three-pin XLR with selectable Pre/Post options that let you choose between the huge warmth of your stage sound or....the stripped focus of your bass when interfacing to live or recording consoles. A Slave Output and Level control allows linking to other power amps, including another M-Pulse for coliseum venues or provides a post- signal output to drive outboard processing.

So if you’re on the search for tone and want to revolutionize your style, check out the M-Pulse Simul-State Bass Amplifiers. Close your eyes, open your ears …and trust your musical M-Pulse.

 Industry Review 

"The M-Pulse 600 is an incredible value.
It scores big points for innovative design, luscious tone, footswitchable flexibility, and roadworthy construction. Mesa's many years of amp building experience have obviously contributed significantly to this design's success. I'm amazed that an amp built this well is so affordable."
