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. Specially developed 10” speakers in the combo version. Two speakers developed specifically for the Bassbase 250 ensure a powerful, percussive reproduction of the amp’s output, replete with precise transient response. Additional tweeter for upper frequency response. An additional tweeter provides transparent highs and accurate harmonic reproduction. Ergonomic, back lit front panel controls. The front panel controls are- arranged for maximum accessibility and simplicity. Potentiometers, function permitting, are center notched for a “memory effect”. Back lighting provides for visibility on even the darkest stages. The Bassbase 250 was engineered to provide you with the opportunity to comfortably create your personal sound. This manual will give you some insights into the Bassbase and familiarize you with it’s features, enabling you to do just that. Have fun with your Bassbase 2501 FRONT PANEL CONTROL FEATURES (1) INPUTS: The Bassbase has two input jacks with different input sensitivities to accommodate basses with passive as well as active electronics. LO INPUT is designed for active basses with active pickups. HI INPUT has a higher sensitivity rating for the more traditional passive pickups. (2) TUNER: Directly above the two input jacks you will find the TUNER jack. This jack is suitable for sending a signal to an external tuning device. Connect the TUNER jack to the external tuning device’s INPUT jack. (3) MUTE: The MUTE switch silences the Bassbase. When the MUTE is activated (MUTE LED illuminates), no signal is sent to the power amp/ Line out/ PA out; only the TUNER jack receives the signal. The MUTE function is especially convenient for silent tuning between songs or sets when it is less than desirable to have audience participation. MUTE is also recommended when switching the power off, changing instruments, etc. (4) GAIN: The Bassbase’s preamp is constructed with tube circuitry, lending the amp a dynamic, warm sound typical of classic tube technology. The GAIN control sets the preamp’s input sensitivity and fine-tunes it to the instrument’s output. Higher GAIN settings add a nuance of overdrive and harmonic distortion. The intensity of the compression effect inherent in tube amplification is also adjusted with the GAIN control. PLEASE NOTE: Tubes need to reach a minimum operating temperature; a few seconds delay between turning the power on and reaching operational readiness are the norm with the Hughes & Kettner BASSBASE 250.

A minimum of effort by you, the player, can achieve maximum effect. (5) BASS: The BASS pot adjusts the lower frequency range and specifically influences the frequency response of the low B, E and A strings. The center position is neutral; turn the pot to the right to increase the low end, to the left to decrease it. The adjustment values are approximately +/- 15db. The center frequency is 90hz.
