i just moved up to a tube about a month ago and i went with the peavy vaule king its relativly cheap and plays ultra nice my guitar teacher actually just bought one. all around there awsome the only one thing i find annyiong is that the reverb tank shakes but im goign to see what i can do about it i probally just got a lemon. but the actually amp is beutiful it has glimmering clean to a squeally distorstion,

well i hope this helps trust me its really nice :)
