Honestly, the PB&J is a cool little digital delay. For a entry level delay, this was honestly better than some $100-$200 delays I’ve tried. “Long” acts as a more normal delay and “Short” seems like it’d be good for Rockabilly or older County. The only negative is the Long/Short switch. It’s defined as “An extra switch lets you choose long or short delay, so you can have 2 different delay settings in performance.” Which would make you think that just the number of repeats would change, but its repeats and delay time. It’s not exactly the easiest thing to deal with live if delay time is important.
