MARKBASS MB STU AMP 1000

Stu is a real rocker and he wanted an amp dedicated to his articulated style but with simple/intuitive 
controls and with a “rock” size to fit the taste of loud guys like him on stage. The new Stu Hamm 
signature amp features both a solid state and a tube preamp with separate level controls offering 
the clean attack of a solid state and the warmth and grit of a tube in a single unit with the mix option,
 plus a 7-band graphic EQ to tailor your bass tone to perfection. The massive real power of 1000W 
from the MPT power amp allows to handle any kind of gigs, no matter how big the stage or how 
loud the band... this amp is always ready to rock hard!  
From a small club to Joe Satriani’s big stage: Rock your sound with the MB STU AMP 1000!

“Markbass has finally given me the sound that I have been looking for! The S.T.U. Amp has beautiful 
solid state and tube sounds that can also be blended together to create the sound that I need, according 
to the musical situation.” — STU HAMM

> SOLID STATE AND TUBE PREAMPS
 The two MB STU AMP 1000 preamps with separate controls for the solid state and tube, offer a wide 
range of tone from clean to crunchy overdrive and distortion and everything in between. You can rock 
your sound from old-school to hard rock or make your own alternative rock tone!

> 7-BAND GRAPHIC EQ
 The seven-band graphic EQ is very useful and easy to use to modify your instrument tone. The seven
 frequencies were chosen to give you total control of your bass tone, even on 5 and 6-string basses. 
Each band can be boosted or cut over a +/-16dB range.

> 1000W HIGH-POWER / MPT - MARK PROPRIETARY TECHNOLOGY
 This high-power head gets amplified by a poweful 1000W MPT power amp, boasting massive supply 
of power and serious headroom. About all the bass amps on the market use the same power amp 
from different manufacturers, which are not specifically designed for bass. At Markbass, Marco De 
Virgiliis invested a lot on R&D to create a proprietary power amp technology, specifically designed to 
respect and glorify the tone of your instrument.
