MiBass 550
It fits in the pocket of a gig bag. Yet it’s big enough to fill a serious venue with warm authoritative Ashdown tone.
Designed from the ground up the MiBass 550 packs 550W of Class D power and a plethora of pro features in a stylish, compact bass head measuring just 8.3 x 2.6 x 6.3 inches – and that includes an internal power supply.
On the front you’ll find a switchable Active/Passive instrument input, input level control that allows you to match the input signal to your bass using the trademark Ashdown VU meter. The newly designed pre amp centers on a 7 band semi parametric EQ for precision tone shaping, use the rotary controls to select frequency and the sliders to cut or boost to the exact amount needed. Add even more low end with the 'Deep' button or instantly switch to a slap happy tone by engaging the 'Shape' button. The EQ can be bypassed completely with an EQ In/Out switch, the output level controls overall volume and what could be neater than a front panel-mounted line input with level control so you can hook up an MP3 player for practicing.
The pro-theme continues around the back, where combination Jack/Speakon speaker outputs share panel space with a Pre/Post switchable balanced DI output for direct connection to a PA or recording console, an FX Send/Return for adding in your favourite effects and a very useful headphone jack for silent practice.
MiBass comes in a range of cool colours – black for the 220W head and silver for the 550W model – with replacement blue and purple panels also available to add a splash of colour. And soon you’ll be able to download a template from the Ashdown website and send us a design for your own unique, custom MiBass front panel – keep checking the website for details.
