1960 Ampeg Jupiter II 720-SN


A rare find, this Ampeg Jupiter II has two separate preamps that can be used in stereo. Very clean and loud even with its 20 watt rating, but that is fairly normal for an Ampeg. Despite still retaining its original Jensen P12R speakers and tubes, the tone is surprisingly bright, as in "piercing pinch harmonics with a Les Paul" bright. The vibrato isn't functioning yet but hopefully it is a simple fix.
