Overview

The Markbass R500 is a bass amplifier head that will have you rocking out old-school, rocking hard, creating your own alternative rock, or shredding up the stage stealing the spotlight from your guitarists! The 500W analog R500 amp (at 4 ohms; 300W at 8 ohms) features a tube preamp that will break up just the way you want it to, and a newly designed limiter that produces glorious distortion instead of cramping your style. The simple 4-band EQ gives you all you need to access a wide range of sounds for any genre. As far as controls, the Gain knob is for the amount of tube overdrive, whereas the Master knob is for your volume.
