NanoBass X4 35w Combo Amp by Phil Jones


Introducing the Suitcase Compact; This model is based on the superlative and uncompromised performance of the original PJB Suitcase. The Suitcase Compact is more powerful, but physically smaller. In fact, it is the same size as our Compact 4 enclosure. It has an incredible punch sound, cutting through air as “a knife through butter,” but with a solid and powerful low end response normally associated with a much larger combo.
