It fits in the pocket of a gig bag. Yet it’s big enough to fill a serious venue.
The mighty MiBass 550 packs 550W of Class D power and a plethora of pro features in a stylish, compact bass amp head measuring just 8.3 x 2.6 x 6.3 inches – and that includes an internal power supply.
At the front you’ll find switchable Active/Passive instrument inputs, precision interactive tone shaping, Deep and Shape switches for instant access to killer sounds, an EQ In/Out switch, an output level control and, of course, a trademark Ashdown VU meter. 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 system or recording console, an FX Send/Return for adding in your favourite effects and a headphone jack for silent rehearsal.
So much sound, so little weight. Order today.

Comments about Ashdown MiBass-550 Bass Amp Head:
I've owned for about 18 mos. Lots of power in small package. I use w/single 8-ohm 1x10 @ home, and w/2x10 4-ohm cab out (small-midsize churches, typically). On front is the VU meter (to set gain level, which can vary greatly depending on the bass; i.e. pickups/pre-amp). Set this first w/output all the way down. This is why a dedicated Mute would be nice. There's an Active switch & a Deep switch (Deep is too much for my setup but should be ok if using 15"). Seemingly infinite tonal variations by selecting Shape, EQ, Deep, or by combining them as desired. The eq controls are VERY sensitive (Bass/Lo-Mid/Hi-Mid,Treble,w/3 Frequency controls). This is why I wanted the unit, but also why I wasn't able to quickly dial in the sound I wanted. Suggest you spend time learning how all of the features interact before you do a gig, if poss. Also on front are the single 1/4" instrument jack, and a 1/8" Line In for a CD/MP3 etc., with a separate Level control (very handy). On the back are 1/4" headphone, FX send & rtn, and Line out jacks, XLR DI out, pre/post switch, and dual 1/4"/Speakon speaker outputs. I've not used the FX, Line Out or DI out, but seems this is all you'd need to connect to a mixer or effects loop. Plugging into the headphone jack does mute the speaker output. The fan runs continuously while the unit is on, & seemed loud for its size, but the amp enclosure seemed to stay cool during some extended use. The power switch is located in the back UNDER the power cord, which is annoying to me. This unit is now discontinued, but IMO is one of the most flexible amps I've used in over 40 yrs of buying bass amps, and comes in a very compact, lightweight and sleek looking package. *Caution - not for anyone who wants to find their tone instantly :)
