Boss RC-505MKII Flagship Tabletop Looper with 5 tracks & Mic Inputs


Just when you thought it couldn’t get better, Boss are launching an upgraded version of their RC505 loop station. RC505-mkII has all the features upgrades longtime users have been asking for: expanded I/O, enhanced mixing controls, customisable FX and Track buttons and much more. 

You can enjoy five simultaneous stereo phase tracks with dedicated controls and faders, now with assignable fx and track buttons.

If you need inspiration to start your track, the built-in library has grown from 85 sounds to an incredible 200 rhythm patterns and 16 drum kits. The newly added Mark Back function also makes it easier to undo and redo while performing.

Input and outputs have been enhanced and now include MIDI in and out, two phantom-powered XLR inputs, three stereo line inputs pairs, three stereo line output pairs.
