Zoom B1X Four Bass Multi-Effects Pedal (Expression Pedal) with Polsen HPC-A30 Monitor Headphones, 9V Power Adapter & 10ft Instrument Cable Bundle

The Zoom B1X Four Bass Multi-Effects Pedal is a multi-effects processor designed for use with electric bass, giving you an expression pedal to provide continuously variable control over certain effects. Offered in an easy to use stompbox format, the B1X Four sports a wide selection of processes, amp emulations, and other features, such as an onboard 30-second looper and a chromatic tuner. With 68 built-in rhythm patterns, you can add drum loops to the mix, which can be quite helpful during looping. Distortion, chorus, and more are all on hand, as are 9 bass amp models that simulate classic combinations. Some effects benefit from the use of an expression pedal, so you can change the effect's amount in a smooth gradual way. You can tweak the pedal's operation in the digital realm through the B1X Four's display screen. Five effects can be chained at any time and in any order. You can save these effects in one of the 50 user-preset patches. Switch among patches (or banks of patches) quickl
