Bassmaster YBA200 Alltube Head

Manufacturer description (go to site for longer description):

This North American built all tube 200 watt bass head stays true to its vintage roots. The YBA200 is a fan-cooled 200-watt all-tube bass head powered by four 6550WE power tubes amplifying the two 12AX7A and one 12AU7 that make up the preamp section. In true Traynor tradition there are no semiconductors in the signal path, glass epoxy circuit boards, solid plywood box construction, solid component selection and an all-metal chassis ensure years of unmatched reliability. We’re so sure of the design and of our manufacturing prowess that we cover the YBA200 with a two-year unlimited warranty.

Basic controls you’d expect to see appear on the front panel of any high end bass amp include input gain, master volume control and a three-band master EQ section. You’ll also see we’ve added innovative new tone shaping features like Scoop, ‘Range’, and ‘Resonance’.

It goes on...
