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.

Markbass R500 Bass Amp - Tube Preamp
Posted by 70x7Sound from Toms River, NJ on Aug 28, 2008
Experience w/product: I own it
Reviewer's Background: Active Musician
Reviewer's Play Style: Rock & Country
The Markbass R500 has a very sweet sounding tube pre-amp (for those who like that tube sound). You can dial-in a very nice classic Rock & Roll sound or deep Country bass. Plenty of power ! This was plenty enough driving one 4x10XLT cabinet. Amp is very light and very quiet. There was absolutely no scratching sound when I turned the Volume or EQ controls. Looks and feels well made. The operators manual was a bit lacking, but the amp is easy enough to figure out. This is a straight forward excellent sounding Amp. The tube pre-amp can be adjusted to permit warmth or nice tube distortion.
