A replacement bass amp tube that delivers your true sound, unharmed.
The Bugera 6550B Tetrode Tube produces high gain without distorting the signal while maintaining crisp, clear highs and detailed lows. The 6550B is ideal for Bugera and most other bass amps. Bugera tubes are subject to rigorous quality tests such as a 48-hour burn-in test and their vibration table test.
