I know it's green but this is NOT a tube screamer. Earthquaker describes it, I think jokingly, as "translucent". It is very transparent and does not color your tone \ EQ unless you want it to. At low gain this thing is basically a Timmy with a slightly different texture to the drive. At high gain it is practically a fuzz. It has an absolutely huge range of gain. It is in excellent condition and includes the original box.
