If I use a Dual Delay with it's Modulation and Chorus Parameters on Zero then the Tremolo effect gets more pronounced. You can even hear the Tremolo effect in the noise when the strings come to rest after a strum before the noise gate closes. I'm wearing isolating headphones and have them cranked up a bit so I'm sure I'm not picking up the standard tuned string sounds.
I'm using public beta 8.7.13
