Pike Amplification Vulcan Bass OverdriveThe Vulcan is a bass overdrive that packs two discrete drive circuits into one package. The innovative color control provides a variable balance between a mid forward, B 15 inspired overdrive and a higher gain modern sound. The signal path is split after the first gain stage and sent to each overdrive circuit where the sound is clipped and sculpted individually and recombined at the output. The result is a versatile overdrive that adapts to any style.
