It’s a Rickenbacker Bass. You know what sound you’re going to get. The basic 4003 has a lot more balls than the classic 4001 but that had the aggressive mid treble growl which is still obtainable by pulling out the treble pot. Get the bass setup correctly to your specifications and it plays like butter. The Ruby with its metallic sheen looks scarlet at some angles and burgundy or crimson at others. Very charismatic looking and sounding instrument. Stands out on any stage!
