Little Bastard 550

£550.00 £799.00

The LB550 features a new version of the much loved LB 30 pre-amp with added Gain control coupled with the 550 watt digital power section from the MiBass resulting in stunning valve bass tone in a loud lightweight compact head.

Rebellious, uncompromising and cool as f***, James Dean - and the car he nicknamed the Little Bastard - are the inspiration for this iconic, all-tube mini bass amp head.

The Little Bastard preamp stage employs ECC83 and ECC82 tubes and features High and Low gain inputs, front panel-mounted Effects Send and Return, rotary Bass, Middle and Treble controls with Mid Shift, Bass Shift and Bright switching, Mute switch, rotary Volume control and balanced DI output. The Little Bastard head partners perfectly with a range of Ashdown US Series cabinets.
