Basshead Series - Bass Amplifiers

Product Photo Options:

The McGregor Basshead provides all the features required to express your talent. We don’t offer a new lifestyle or a new image with this product, simply a product designed for a long and trouble free life. The tonal qualities, input options and extended headroom distinguish these amplifiers as exceptional products and their speakers will simply mimic your chosen sound with effortless precision. These amplifiers are suitable for Double Bass, Bass guitar, Acoustic guitar or even Violins.

The Basshead Amplifier is ideal for musicians looking for a compact, fully featured, powerful amplifier solution.
The Basshead is dual channel amplifier so with the flick of a switch (or the use of a foot switch) you can change your tone or sound level for those featured solo parts requiring high impact. Alternatively, fast dual instrument selection can be achieved.
The Dual channel preamps selection is via a foot switch or front panel selection (should you forget your footswitch). Channel A and Channel B both provide visual indication of the channel selected via LED status indicators.
A line input with level control is provided for those that want to practice to a backing track or simply expand the system further.

The Basshead amplifier is available as a head or in a compact combo format with tilt back as a standard option.
The Combo 10" driver and HF unit provide exceptional results thanks to the inbuilt, carefully designed two way crossover that operates at 12dB / octave.
