A beautiful example of how old and new technology should work together.
The Markbass Classic 300 bass amp's heart beats with the power of JJ Electronics tubes--2 ECC83 preamp tubes, 2 ECC99 tubes, and 6 KT88 power tubes--which give you the warmth and fullness of the great old amps that are now aging or retired. A massive 300W of tube-driven power will handle just about any venue imaginable.
But times have changed, and this bass head comes with a brain: an onboard microprocessor re-biases your tubes every time you start up the Markbass Classic amp. This allows you to customize your bias adjustments, and tells you if and when any tubes need to be replaced. Tube amps used to be finicky and unreliable. Now you won't have any nasty surprises during a gig, and you'll know exactly when and how your tubes need to be serviced. To top it off, the Classic 300 bass head puts out a loud 300 watts of power. It also has a 4-band EQ, plenty of I/O, and a 2 x 16 LCD screen which can be used as a VU meter or for displaying other important parameters you choose.
