500 Watts of Original British Bass — The Ashdown UK-OBM-500

The Ashdown UK-OBM-500 Original Bass Magnifier is a 500-watt bass head built in the United Kingdom, delivering the full-bodied, harmonically rich tone that Ashdown Engineering has been known for since 1997. Compact, powerful, and unmistakably British, the OBM-500 is designed for players who demand professional-grade performance without compromise.

At 500 watts into 4 ohms, the UK-OBM-500 provides ample headroom for rehearsal, studio, and live performance. Dual speaker outputs give you flexible cabinet pairing options, and the lightweight 2 kg / 4.4 lb chassis makes it one of the most portable 500-watt heads on the market. Finished in Ashdown’s signature Ice Blue, the OBM-500 carries the iconic Ashdown aesthetic with the Double Wing badge and premium build quality expected from a UK-made instrument.
