I've been reading up on the potential to achieve an effect similar to double-tracking by setting delay to ~25 ms with a single echo. What I want to know is, can I find a delay pedal that will allow me to play that single echo at ~25 ms without playing the original signal? Here's why: I want to use a y cable splitter to run two separate signals. One signal will be distorted, while the other will be fairly clean; likewise, one signal will be delayed, while the other won't be. Ultimately, I want to sound like I'm having a clean guitar and a distorted guitar playing together. Are there any alternative ways to achieve this?
