I just looked at the video you mentioned up close, and I'm pretty sure it's one of these.

Probably got a lemon. That sucks!Owned a new GK MB150E-112 in 1992 that died on a gig- 3rd time I used it. Piece of crap or unlucky? Replaced it with my Ampeg B1 combo which I use to this day. Lighter, more modern addition is my Acoustic Image Coda S4 Plus.
Should have come this way from the factory.Re rattles. I purchased my 2nd MB150 used off of Reverb and discovered the grill rattles at certain frequencies. Tightened screws and helped some, but didn’t fix. Upon trying to remove the grill, I discovered it had been surgically glued in! So, I used a bungee cord and pipe insulation to keep pressure on the grill. It works!

Probably one of the best things I've seen on tb.Re rattles. I purchased my 2nd MB150 used off of Reverb and discovered the grill rattles at certain frequencies.

GK has some combos that are similar, pricey.
I recently got a Mark Bass CMD 1x12. Sounds good, 28 lbs
and plenty of power, DI out, good EQ also.
GC has been running a sale @ $750.00.
I paid $950 last year.
I've heard this description of this amp for many years, and I can only say that different pickups and different basses will respond differently to each amp. Mine sounds warm and thick in the mids. IDK? I've owned AI, EA, WW, Phil Jones etc. and I usually come right back to my 200mb.I too had a GK black metal box for over a decade when I was working a lot - 300+gigs/year - and I loved it. It started falling intermittently so I bought AI stuff. A couple of years ago I dusted off the GK and got it repaired. I was astounded at how boxy and nasally it sounded, so I put it in the classifieds and got rid of it. I think equipment is improving. When my AI dies I'm sure I'll find something great. BTW for subway travel to gigs the PJ Double 4 with a preamp is pretty cool. That new improved Cub looks interesting.
