This amp is essentially new, in perfect condition, with no flaws. Redplate's top of the line amp. A very powerful amp with more tonal options than any amp I've ever had. It can use KT88 tubes for 88 watts or 6L6 tubes for 50 Watts. It currently has 6L6 tubes in it which is my preference. It has a clean channel with different gain options. Drive #1 is a Dumble style overdrive that changes character based on what gain options are chosen in the clean channel. Drive #2 is a Marshall style overdrive that can stack on top of Drive #1 or without Drive #1 engaged. Drive #2 has EQ controls that can give it a lot of bite.
