Congratulations on your choice,

the Hughes & Kettner BassBase

 250!

The 

BassBase 250 was 

designed by a group of musicians and technicians to

meet the needs of the professional bass player.

Superb tonal characteristics and sophisticated features define the 

Bassbase 250 as

a professional bass amplification system. Both the compact, easily transportable
combo and the elegant head versions of the 

Bassbase 250 are 

at home on stage and,

thanks to sophisticated signal routing possibilities, in the studio.

The Basebass 250 is available as a combo or an amp head. The amplifiers are
identical in both versions, with the exception that the combo comes with a speaker.

Sound quality through tube technology.

The 

Bassbase 250’s 

preamp is constructed utilizing the classic ECC 83 tube. This

tube is responsible for a lively, dynamic bass tone through it’s innate compression
characteristics and carefully dosed upper frequency range. The basic tone of tube
technology is most convincing; from a dark warm jazz tone through to an articulate,

punchy rock sound, down to the high attack of funk, the 

Bassbase 250 

can do it all.

Carefully balanced tone controls with a parametric midrange.

The four tone controls enable you to quickly and efficiently dial in your own basic
tonal characteristics and allow for dramatic modifications to suit your needs. The
midrange of the musical spectrum is paramount to a good baas sound therefore,
the 

Bassbase 250’s 

midrange can be adjusted parametrically.

250 Watts of dynamic power with "DynaClip".

Bass amplification demands a great deal of power. The explosive dynamics created
when you play with a heavy attack drive conventional bass amps to the limits of
clean sound reproduction. Annoying distortion, apart from endangering the speakers,
restricts the output potential. The 

Bassbase 250’s 

newly developed "DYNACLIP"

circuitry suppresses the distortion created through dynamic peaks without limiting
the dynamic spectrum.
