all of these sound broken to me
This is actually fascinating to me. The amp sounds wildly different in all of these clips.
So first of all, this really leads me to believe something might be wrong with the Obsidian they sent me.
In the third video with all the knobs at noon, sounds NOTHING like mine. I mean, absolutely fucking zero in common with my amp. Now, I don't know what tuning this guy is in, what speakers and pickups he's using, microphones, YouTube processing, etc, but it sounds a world apart from my amp. Even when I used my Drop C# Les Paul Custom with a Motor City Afwayu (big, thick, hot, fat pickup) it sounded absolutely nothing like this and I had my treble at 10:00 and my Detail at 8:00.
The second video just sounds like total ass. He must have the mids on zero or otherwise set up the amp like an idiot. Not much nice to say about that one.
The first video is interesting, too. The tightness at the beginning of the clip is exactly what I meant by "choked at lower gain settings." You can hear how the amp is just so tight it's asphyxiating the guitar. BUT, when he turns the gain up to 3:00, the amp suddenly fills out and comes alive. That's exactly what I referenced in my post. It's not necessarily a bad thing; many amps do this (fill out with the gain knob at a certain setting), but it does make that channel a bit of a one-trick-pony. When he switches to the Lead channel at :30, that sounds
nothing like my amp either. My amp was absolutely unusable on the lead channel. It had SO much unusable gain. He has his Lead channel at noon and it sounds heavily distorted but still clear and I don't hear any feedback. My amp was over-gained and feeding back like crazy (my pickups are all potted, relax). His settings are a bit more conservative than video #3; more in line with where I had mine, but the amps still sound very different.
TLDR - These clips sound nothing like my amp. My amp might be broken, so I'm glad I'm going to send it back to them. We'll see what develops.
One thing I was considering, too, was asking him to retube the amp with different power tubes. Maybe EL34's are not the way to go on this amp. I have read a lot of people saying KT66's sound great in this amp. Perhaps I should request that if he says that something was messed up, just as insurance so to speak.
