Description there's a REAAAAAAAAALLLLY good demo of the B3k from the bass player for Attack Attack (the European one, not the crab-core American 'un) with mostly fingerstyle. this is the different sounds that come out with light and heavy distortion with the Attack and Grunt switch in different positions with some simple tapping and chording. THIS PEDAL EATS BABY FACES. signal chain is a Dingwall AB I 6'er into a Rusty Box into the B3k into a Motu 828.
