Well it's happening again. As much as I love my Carr Rambler and Goodsell Super 17 MK2, the MK3 at 29lbs has caught my eye. My back acts up from carying the Rambler and even the lighter, 38 lb, MK2. The Mk3 at 29 lbs looks like it can do everything I need in an amp especially the tone and 5/17 watt option along with reverb and tremelo. I've been fortunate with the Rambler and MK2 by picking them both up used on The Gear Page. I may have to pony up and pay retail for the MK3. It looks like a keeper. Anyone got a MK3 and ar happy with it? Is there an option to plug in an extention cabinet and run it at 4 ohms? Are these things readily available? Who is the best retailer to call for one? Thanks!
