Wish I could dude, I built that when I had access to metal working machinery, which unfortunately I don't any more. Real bummer. I wish I could still do stuff like that :/
Checked you guys out. Sounds fucking killer, some nice riffs in there. I couldn't hear where you'd use a Tremolo. Tell some examples. A Flanger on the other hand would sound real cool on some short bits. Even a wah.
How did you want to use the Trem? What type of sound are you looking for?
Despised sold it to a guy here in Aus. I will try find who it was. As for the trem, could be good depending on the application. I know Opeth use a tremolo, and its really cool. If you play some small/clean melodies a trem will add awesome dimension. If its just balls to the wall DM then I prob wouldn't bother.
