I came across an interesting video by guitarguitaruk demo’ing the TC Electronic Flashback delay to achieve the Edge/U2 sound. Sounds like he’s representing quite well. Seen a few comments stating to just get the Nova Delay, but for the price point on the Flashback, it’s really quite affordable getting this sound.
Here is the video:
Here is the official description of the TC Electronic Flashback Delay:
The Flashback delay features 6 seconds delay time of every delay type you could ever wish for, from the TC Electronic legendary 2290 to a slapback, with 10 different types to choose from and it also doubles as a looper!Besides all that, the Flashback delay comes with TonePrint, so you can easily ToneTransfer your favorite delay settings. The Flashback delay also features TC Electronics audio tapping technology, allowing you to set delay times by strumming your guitar, and a toggle switch allows you to switch between 16th notes or dotted 8s, for a more U2-like sound.The Flashback features a spillover on/off switch as well as Delay Time, Feedback and Repeat controls, so you are always sure you get the sound you want without any hassle. Rounding out the pedals features are a small footprint, easy access battery hatch, true bypass, an analog-dry-through and the highest grade components.
