As Nick correctly states, the amount of guitar presets w/distortion is really limited.
In case you want to try them out without built-in disto, you can simply bypass the first FX block in the preset. As an example, take preset #450 GTR rack, load it and press Parameter; now turn off FX A and you'll only hear delay and diffchorus.
Keep in mind that there are dozens of presets that do not use distortion and provide the fx you may need on your gtr. The name of a preset dosn't really imply you should or should not use it on any particular sound source. The best approach is to sit down and hear them all.
As a starter, try 444 Chrs/Dly>Verb.
I'm in the process to add more presets for this task, besides other stuf that will be fun for many.
