So question.

Is it safe? I know that plugging one amp into another always has potential to do some damage, but if you're going from the headphone output rather than the extension speaker or line out, I feel like that might not be as bad? Better get a second opinion, but if it is safe, you can make a bypass box to plug the orange into that allows you to chose either to send your guitar directly into your sovtek, or to go via the orange into the sovtek.

Oh yeah, that should be fine, then. I was thinking that it was one of the bigger orange crush amps (didn't catch that "micro" part). I have one of those smokey cigarette box amps that I've done the same thing with. It's instructions actually recommended plugging it in for use as a fuzzbox. I don't know what kind of guts the orange has, but the smokey amp is nothing more than a lm386 IC and two caps (10 uf, I believe...) that's it! So, something like that would be pretty easy to build into a pedal of its own...or you can just use the bypass loop idea. It would perhaps be a bit more useable if you had a true-bypass loop to plug it into that had a clean blend option built into it, (see my clean blend thread)
