Interesting - having watched 'Bloodstream' live looped at the Brit awards & been quite impressed by the performance .....
Had a look for what Ed is using to loop (huge looper with screens) - this is what I found.....
As looping is a crucial part of Ed Sheeran's performance, he and his guitar tech decided to upgrade to this custom built unit, which allows for better sound quality, better looping and better control of the sound at bigger venues. According to his guitar tech, Trevor Dawkins:
"We needed to source a pedal that had separate outputs for the guitar, percussion, and vocal elements of the loop, allowing for separate treatments (reverb, echo, harmonizer etc.) at the front of the house, Chris and I spent about 6 months contacting every pedal manufacture worldwide that we could think of to get someone to help us come up with a pedal that would be future proof and sonically superior to the RC. Although a couple of manufacturers were interested, no one had an existing product that really came close to what we wanted to do in terms of numbers of outputs and attainable loop lengths."
The "Chewie Monsta" is not an FX pedal, it's a sophisticated, unique pedalboard controller that Ed uses to manipulate a Roland FC300 MIDI Controller which is placed off-stage, described by his tech as the "brain behind the looping system." The pedal controls Ed's new looper: a Mobius 2 VST plug-in, hosted on Ableton Live. (For more info on Mobius, which is a FREE software, visit circularlabs.com)
The Monsta has four Roland double pedal-type switches as well as two video screens to monitor the program’s record/overdub/playback functions as well as showing the time frame of the loop itself. The two far left switches (REC / STOP) are part of a Boss RC20 pedal, because Sheeran wanted to keep the same familiar feel. The remaining switches are taken from three Boss RE-20 pedals. Watch him using it at Glastonbury 2014:
"The pedal allows Ed to record, overdub, and play back on any one of four synchronized loops, each of which has its own output, allowing us to now have the guitars, percussion and vocals separately, which is invaluable in a live situation. Ed can also now mute the loops individually, allowing him to alternate between different sections, such as a verse/chorus scenario. We also have an undo function, which allows Ed to clear the last overdub on the selected channel, should he need to."
Live, besides his guitar, Sheeran also plugs a Sennheiser e945 to the controller, which is used to loop his vocals. At gigs, Ed uses two mics. The second one is not for looping, it's used just for a clear signal.
