Hey again @PAD
I watched the video 15 and downloaded the Logic project + resources files to check this out and no, this "solo guitar" RP Blue preset isn't included in the resources. The tutor mentioned it in the video at 0:53 "I wished I could find the original preset but I wasn’t able to find it" and apology about this again at around 7:25. In fact the video is there to help people recreating this sound and RP Blue isn't used in the available Logic Project, the "Guitar Solo" track is audio only.
But you will find the Guitar solo.mid as well as the Guitar solo.wav audio render in the resources. Best option here is to use any other synth that has a similar dry electric guitar sound and process it as the tutor was showing in this video. Now if you own RP blue, it might be a factory preset ? Can't tell, I don't have this soft-synth myself. If you have ANA 2 there's a "WahWah Guitar" preset that might do the job if you disable ANA 2 internal effects, but again any similar dry guitar sound with a similar effects chain should get you close to the track sound. It's also a good practice & habit IMHO, you won't always have the same plug-ins or sound sources as you see in tutorials or listen in existing tracks, so trying to re-create them with your own tools is definitely a valuable learning practice, even if it's less easy & more time consuming than using a preset.
Hope this helps
