“Made by JEN Elettronica in Pescara, Italy in the 1970s. It plugs into your guitar jack and has an adjustable bass/treble control. The sonic range of this unit is quite wide. It can sweep from bassy bass to ear piercing bright treble. The JEN PE-403 is electronically identical and looks exactly like the VOX model, except the label was changed. Even the diamond pattern on the JEN label is the same as the Vox.”
