I've had a thread in the amp section: http://www.talkbass.com/forum/showthread.php?t=578859&highlight= But recently found myself wanting a Gibson Thunderbird 4 string... The UL310 series 2 is the lighter 47 pounder with new cover and is in mint consition. If you have a good condition Thunderbird to offer I please PM me... I'm in the Baltimore, MD area. Thanks!
