Mac DeMarco’s Akai Headrush E1 Delay

According to an interview Mac gave to Reverb.com in 2019, this is among the first, if not the first effect pedal that he used.

And then I think I got a delay pedal at some point. And I was like – okay, it sounds like John Lenon on the vocal, that’s cool. I like that.

It’s unclear when exactly Mac used this pedal, but it seems impossible to find any photos of it. In the same interview with Reverb, he sort of tells the story chronologically, how he first played straight into a Twin Reverb amp and then got this pedal after a while. The Twin Reverb he used from around 2011, so probably sometime in 2012 is when he got this delay.
