Great 50 watt all-tube amplifier for guitarists and bassists. The power can be reduced to 35 watts. With 50 watts the amp sounds brilliant and fast transients are transported very punchy and clear. With 35 watts, the amp sounds softer, has rounded treble frequencies and compresses more easily. Nevertheless, the punch is never lost thanks to the large transformers.


Special edition with full front panel with "On Guitars" logo, tweed back and black leather corners. Cover included.
