I was originally just going to order the standard 5 preamp tube kit from Doug's tubes, but then I got lost in a forums. I have a 5:50 plus combo, stock speaker and Mesa 440 6L6GC power tubes. I play everything except metal. Does anyone have any recommendations? I would like the gain to be the same if not a bit less than standard with plenty of clean headroom. I get my OD/Distorted sounds mainly from pedals. I mailed Doug and his response was to get the tone kit, but I've seen lots of other combos and just wanted to get something I would be happy with.
