Got alot of tax bucks coming back and I had recently tried out my coworkers 1994 wt300 and LOVED IT. only one problem. It cut out ONCE in ten times of playing it. not sure if it overheated, couldn't get it to do it again, I even tried for 45 mins to overheat it. He wants $400 for it. it looks very clean too! also wondering if I should go bigger Eden like 400 or 550, but I like the 15Lbs of the 300. This head would be for my "mid sized rig" eden wt300/aguilar gs112. should I do it? or get bigger newer eden like 400 or 550? what would you do?
