OVERVIEW:

Congratulations on your choice of the 

M-PULSE 

as your Bass amplifier. This latest offering is our most comprehensive amplifier 

for electric bass and it brings together both new and old technology, solid state and vacuum tube design to create an instrument of 
unparalleled performance and soulful sound.

M-PULSE 

amplifiers start with an all-tube pre-amp for the most musical response and this feeds the three standard rotary tone 

controls BASS, MID and TREBLE. Most first time players comment that we could have stopped right there after hearing the sweet, 
tight, huge sound from this first section of the 

M-PULSE 

pre-amp. But that’s just the beginning!

From there, signal is routed to an ultra-powerful 5 Band Parametric Equalizer that has been optimized for the frequencies found on 
today’s 5 & 6 string instruments. A bandwidth from 30Hz to 12Khz is found on the 5 frequency controls and each overlaps to assure 
a smooth transition between bands. The 5 GAIN controls allow a boost and cut of 15db in either direction to provide 30db of band 
specific shaping power. This EQ can be assigned On, Off or Footswitch, which is activated when the 

M-PULSE 

Footcontroller is 

connected. Build a rich, complex, sound utilizing the parametric as your main voice or, add the EQ for a footswitchable solo or slap 
sound to an already amazing fundamental tone...either way this 5 Band EQ is a great addition you will come to find invaluable.

Next in the signal path is a new improved Compressor that features both THRESHOLD and RATIO controls. First included on our 

M-2000 

Bass amplifier, this updated version allows for much greater fine-tuning of the dynamics. The THRESHOLD control is extremely 

sensitive to your attack and can be set for either subtle or dramatic compression effects. The RATIO control allows for anything from 
slight dynamic trimming all the way to a hard knee squash with a range from 1:1 to Infinity. The Compressor is also assignable On, 
Off or Footswitch giving you the choices of active or inactive all the time or triggering it remotely during a performance as an effect.

After the Compressor we jump over to the Output section that serves up the mighty 

SIMUL STATE 

power with its awesome 600 (or 

360) watts of rich, tube-driven MOSFET tone. This innovative circuit combines the best attributes ot tube and solid state technology 
to  arrive at a magical blend that breathes and yet, tracks tight while producing massive power.
This power is interfaced to you via a pair of Output controls that serve as overall MASTER VOLUMES. These are MAIN and SOLO and
