This is one of those items you just want to have in your gig bag at all times. Some cabs only have Speakon, maybe your amp has jack, maybe this cab should fit both, but the jack doesn't quite fit (I'm looking at you, Gallien Krueger).
Just have this sitting in your bag, and those frustrating moments are in the past. The build quality is more than decent, especially at this price point. Gig bag essential!
