You are now the proud owner of a Crate V33-212 tube guitar amplifier. This combo amplifier packs a whole lot of vintage tube sound and classic spring reverb into its compact cabinet, providing you with an amp that is portable and easy to operate, yet still pro- duces incredible sounds! The V-Series amps offer the versatility required for many different musical styles, and have the unique tonal purity of a hot-rodded tube amp. The V33-212 is a two-channel amplifier with channel-switching between clean and overdrive sounds, gain and master volume controls, treble/mid/bass tone controls, global boost and presence switches, and an internal spring reverb. It cranks out 33 watts from a set of four EL84 output tubes into two internal 12” speakers.

Each amplifier is tested to confirm that it meets our specifications, and we believe that this amplifier is the absolute best that it can be.
