Trick out your bass rig with the perfect bass guitar amp accessories. To start with, you'll want to grab a cover for your amp or speaker cabinet. It's amazing how much damage dust can do, and a quality bass amp cover from Sweetwater could save you a lot of grief in the future.

Our bass guitar amp accessories also include a great collection of replacement speakers from Celestion and Eminence. These aftermarket speakers make it easy to upgrade any amplifier. Whether you need a set of 10" speakers or a single thumping 15", we've got it.

Alternatively, you can ditch your bass amp altogether with a quality attenuator or simulator. These let you run directly from your favorite amp right into the PA or your recording system. Whatever your bass guitar amp accessories needs may be, Sweetwater has you covered.
