Well I've gone ahead and purchased myself a used bg208 somebody was selling and have spent the last hour and a bit messing around with it, and to be honest I have a fairly mixed opinion about it.
First of all in terms of weight and portability I give it an a+. The ability to add an extension cab is great aswell. The TonePrint options are surprisingly nice aswell, there's quite a lot of them that are quite useable and a lot of others that aren't. Furthermore having to hear the loud screeching sound from my phone everytine i want to switch the toneprint quickly got extremely annoying.
But to get to the point it really doesn't sound good at all. I'm playing through a passive aria pro II pj bass and it's extremely bass heavy and lacks definition in the highs. It almost sounds like there's a constant sub octave going on and my tone knob is rolled down, neither of which is the case.
And as for the eq, the tc electronic "smart" eq is extremely unnatural sounding. Dropping the bass literally sounds like some frequency are simply dropped. Cutting the highs makes it sound like it's underwater. Boosting either doesn't allow for any pleasing tone either. The most acceptable sound is a flat eq and even that suffers from overbearing bass and missing highs.
I'm left quite sorely disappointed to be honest by the whole ordeal. My old Hartke hd25 watt 1x8 combo sounds vastly superior...
