The Mark Bass Little Mark Vintage Goldline Bass Head 500w. Condition is pristine, but have to sell it as used, I bought it as a spare head, which is not required now, gigged and rehearsed only a couple of times, to try it out, lovely warm vintage tones available with this amp. The quality of this Markbass head it superb as you would expect from this top manufacturer, but they seemed to up there game again with this range. Will be shipped in the original box. Plenty of tutorials and reviews online. Thanks for checking out my post.
