The QUAD Stack speaker cabinets are built to professional specifications using multiple-ply hardwood and covered in tour-ready vinyl coverings with vintage-style grill-cloths. Each Kustom cabinet houses four Super 65 Celestion speakers to provide both crunchy rock n' roll tones and warm, detailed clean sounds. Cabinets and heads all feature a chunky, die-cast Kustom logo for easy onstage identification.
