Bluetone Ace of Bass Head is 300 W full tube amp for bass players. It`s topology is based partly on Fender Bassman and partlyy to our own design. Amp has an ultra linear 4xKT-120 power amp. KT-120 tubes are pretty new in the market sounding very closely 6550/KT88, but giving double output power compared to those tubes.

Amp is one channel model including normal Volume, Teble, Middle and Bass pots and also a Bright switch + Master Volume. Speaker connections are with mono jacks and Speakon connectors. This amp has an external bias point. With a Bluetone Bias Rate meter it is extremely easy to bias power tubes when changing them. 4xKT-120 version has also an internal fan to cool power tubes.

DUE TO PROBLEMS WITH KT-120 TUBES, THIS MODEL HAS 4X6550 POWER TUBES GIVING SOME 200 W OUTPUT POWER
