I heard it would only possess the Lone Star reverb. I have a Road King, but have no use for the power amp selections/Progressive Linkage. I enjoy the options, but feel it's hard to get dialed in permanently for performance. I don't even own a Road King cab, but a basic Rectifier 2x12. With the open-back Road King, I feel the problem is a poppy too-much-mid distorted sound, with some buzz. The Roadster is going to be closed back, and I will try to purchase one. I'm supposed to receive a custom Road King 2x12 combo in Cream Bronco with Wicker Grille, but some piece of hardware is on backorder from a manufacturer supposedly, says Mesa. I have a black Road King 2x12 for the meantime. Does anyone know what the policy is on changing an order and/or when/where to pre-order a custom Roadster in the same color?
