The Line 6 Spider IV 75W 1x8 Modeling Combo Amp brings together an entire universe of rig tone and effects in an easy to transport package. Built on the foundation of a 12" Custom Celestion speaker and a large LCD display, the Spider IV 75 allows you to toggle between eight onboard SmartFX including phasing, flanging, and reverb. The star of the show is a four-channel design with eight amp/cabinet models to go from a bluesy twang to searing distortion with the twist of a knob.
