I use a Fender Rumble 200. Black tolex and silver face. Very lightweight and loud and growly. Solid State. 200 watts.

I am hoping to get a 4003 very soon to play on it.

Got one bass, two mids, and one treble knob for the eq. All I need. Overdrive channel. Gain, Master, three push button pre sets, or just use no presets and run straight, which I do so far. Ground lift, phones, XLR out, horn on off switch. min pin aux. effects loop. Ground lift.

I'm running my 4003W through a Markbass Mini CMD 121P Combo, and a NY 121 Cab.

I just changed out the Markbass for a Fender Rumble 500 Combo. The 4003W has a really nice bottom to it with the twin Eminence 10's onboard. It's 350 watts @ 8 ohms, with out an external cab plugged in. And it's a wood cab. I like that.
With the Fender amp, if I have an issue, it's easier to deal with than with Markbass too.

Someone fill me in with the gear I have. Surely, some of you know what I use these days.

Running a Zoom B3N multi-pedal, using the SVT modeling for 80% of what I play, the other 20% dabbling with the Fender Bassman and Aguilar models. Split the DI to the Mains and to a 250w powered floor monitor. Love what I'm getting now. Experimenting with the MarkBass and Acoustic 370 models, waiting for more to be added by Zoom later as downloads (B3N only been out six months or so -- based on previous models with earlier pedals, hoping we get Hartke and Marshall models soon).
