Classic Monster Fender 1992 Twin Reverb Tube Amp ( The Twin ) / Verification of age is on the back of the amp which states CE which means that it was manufactured in March of 1992...it is now 34 years old / I purchased the amp in 1992 as an investment and it has been played only a couple of times...and stored in my closet for 34 years ...it has never left my house / amp is on rollers / everything works great including the Reverb but the Reverb control button - knob is missing and is in need of a new one to be installed / you can also bypass the reverb and use a Boss Reverb Pedal...just a thought.../ if you Google " What is a 90's Fender Twin Reverb amp worth "...the answer will be between $1000 and $1200 / I also had a new padded leather cover made to protect the amp when in transit which I paid $100 for...and that looks brand new also
