Simple ...
Ultrabass may be useful but fun anyway
Equalizer satisfactory
Footswitxh useful
A little heavy, regrets the absence of side handle

UTILIZATION

No problem is instinctive

SOUNDS

His asser cold
Lack of serious (it is 12 "only)
His asser powerful anyway, good potato (me with a good passive anyway)
Best used with an amp modeler to have better bass (Korg PX4B very well ...)

OVERALL OPINION

Correct amp for the price
Enough to play in a group with drummer
