Nothing fancy. No extras (piezo, quilt top, etc.). I'm more than curious to hear from some folks that may have both in their arsenal. Just thoughts, different situations for different basses, nitpick, best feature...... And I guess I should specify a SR5 with the single MM. Besides, not too many have played a double hummer. (please insert crude remark here ) If it's of interest I do mostly blues and rock. A little jazz when I can find the time. Thanks, you guys rock.
