  1. A few years ago I rebuilt my soundhouse amp, with the first cord played through my Arbiter les paul copy and a set of sound house speaker cabinet (fanes) it just scared me ,shear hell power, the shed shook and the possums left. The amp reeks of Sabath , the amps has the what it takes to make it a classic.
