Thank you for the warm welcome and advice guys, it's truly appreciated. I love this place.
bassjones, you should try one of the Sansamp VT pedals with that Markbass, the VT pedal with a LMII KILLS

I think it would with that head too! I had actually considered a Low Down Sound 8x10, but I sure don't need anything that big anymore lol. I am cabless right now, but I had an SWR Henry the 8x8 that was amazing, loved that cab.
alanknm, the doctor advice is a great idea, I am really out of shape and my dad died young after suffering from heart disease for many years... unfortunately I have severe anxiety disorder and doctors, doctors offices, hospitals, etc. are my biggest trigger. I simply can't do it. If there is something wrong I'll find out when I keel over walking or biking I guess. I'd prefer that to a trip to the Dr., let alone a trip where I'd likely find out that there are some issues.
Headed out now for a walk, gonna shoot for 20 or 30 minutes.
Thanks again for the warm welcome guys
