Mike uses a SX Tradiational Series 4-string bass. He has been known to whip out an Ibanez SRX505TK 5-string bass on stage. For amplification, Mike uses Sunn 1200-S bass amp, which powers 2 Sunn 410-H cabinets. A Shure Wireless Receiver ties him to his amps.
Chris plays a '61 Gibson SG. As an amp, he runs directly into an overdriven Peavey Bandit 112. This amp has been microphoned directly into 2 Marshall 4-12 cabinets. Onstage, Chris likes to keep it simple, no pedals or effects to get in his way. Its all Van Haren on stage.
