Be very, very careful with the Samson stuff. I have a CR77 sitting on a shelf and it'll never get near my amps again. I don't know why I haven't thrown it away.
First, yeah, the white noise thing. That's definitely coming from the Samson. Annoying, but in the immortal words of Douglas Adams, "mostly harmless."
Output gain, however, has some serious freaking horsepower, not all of which is safe. The volume knob got jostled to a higher setting without my realizing it (all to easy to bump this knob) and did something evil to the input of my JCM 900. From that moment on, the Marshall just emitted a loud squeal, so off to the service shop it went.
I took the Samson out of my lineup and have never trusted it again. Which is a shame because I really, really like the bug concept. I don't know what they're thinking on the output specs, but allowing 1.21 gigawatts of power to hit the input of an amp is a Bad Idea.
Thanks for this Chris. I've been using mine for about 4 years now ( previously used the Airline Ar1 thingy) and not had those issues at all.
The guitar "bug" set up is perfect, if only the line 6 G10 was....better...I'd switch in a heartbeat.
