Now that my band is gigging, I came to realize that on stage all my bass frequencies were blowing past my knees with the 2x12 I was using, especially on stage. After reading around on talkbass.com, some folks were saying the Powerhouse 2x10s actually pair well with the Powerhouse 2x12s, so I figured I'd give it a shot. They are harder to find than you'd realize used, and I didn't want to drop $729 on a new one, so I found a used one in good shape on GC's used site for $349.
I also dumped my M6 Carbine and replaced it with a GK MB Fusion 800. It is very Carbine-like in how deep the lows are and how the highs are voiced in a modern fashion, but the low end is much easier to control. It also has 3 12AX7s in the preamp to add some natural preamp grind with higher gain levels. Plus it is 800 watts in a 5.5lb package. The Carbine had a few issues that my local Mesa tech fixed. I'm enjoying it so far.

I also ended up buying a Squier VM Jazz bass from my local Guitar Center for $150. I ended up really enjoying playing a Jazz style bass but decided to build one myself out of parts, so I set about acquiring the parts.
MIM Deluxe Jazz bass body
Warmoth Jazz neck
Black Gotoh 201 bridge
EMG JVX pickups
EMG BTS system for a blend and bass/treble control
Black Gotoh tuners
Flat black pickguard from WD Music
The neck plays awesome, and that was without a final crown and level done on the Warmoth Jazz neck. For the record, I normally prefer thick necks - not necessarily wide, but deep front to back. The Warmoth neck is a LOT thicker than your typical Jazz, but I think I found the perfect neck for my hands. The bass growls, it cleans up, it can be burpy, and can slap. It seems to handle everything my cover band throws at it, and we cover stuff from the 70s to the present. I was honestly surprised with how well it turned out. I'm really considering selling off a couple basses and building another one.
This is what I was going for when I built it.
That bass looks great. Kind of a Roger Waters J bass haha.
