I acquired this head a couple of years back as New/Old Stock when my uncle bought out the *House of Music* in Springfield Illinois... it has been professionally assessed and cleaned, and operates absolutely perfectly with that classic Ampeg sound that nothing else provides...

*Open to trades for basses/guitars...*
