I'm working on a song that has a pretty big echo in a spot. I can match the timing by adding a delay to the tone, but here's the problem...

 

When doing Riff Repeater at below 100% speed, it gets all wack. The song's delay effect gets slower, but the guitar's delay remains the same. So I'm not sure, but this could be pretty annoying for anyone practicing at a slower speed, so this might just be a design decision.

 

Should I just remove the delay in the guitar tone?

I wouldn't remove it. The delay part will sound good when you play it at full speed, you can't really do anything with the tones when the song is slowed down in riff repeater. They can always switch to their own tones when they are practicing in riff repeater if it sounds annoying that the delay doesn't match anymore. 

Hmm. I took the delay off for the version 1.0 release. I guess we'll see if people want it back. It should be in there if a person loads the tones of the song from Rocksmith and uses that for their own tone.
