Thanks Axe! The sound is all from the BOSS JS10. As mentioned before, it really doesn't sound that great through its speakers, but really nice with headphones and records pretty well. For what its worth, I'm using the "VO Lead" (I believe its stands for a VOX amp model) amp tone. I made my own custom preset right away, essentially copying the settings I had on my BOSS DR880.

The gain & level are around half way, and there's some chorus and delay in there too, and I think some reverb as well.
