Obviously knowing what you are doing playing give you a huge leg up, and true, a Peavey TNT can be had cheap currently, but those were really good sounding amps. I will say this, with my first bass amp cir 1968, a Lafayette (A vanity line for an electronics store long out of business, and who knows what company actually made it), there is no way you were going to get a respectable sound out of it Compared to my Eden gear regardless how well you play. JMO.
Yes, definitely talking "basic necessities" fulfilled, such as an amp that can produce enough low.
I've stayed away from the "refined" amp market because I don't need super tone shaping nor advanced preamps. I've carried my tone with me since forever, in different devices, lately either a Zoom MS-60B or a B1X Four (have a rack with a SansAmp RBI+Hartke 3500 head+wireless+tuner that hasn't left a stprqge for years, those pedals can do the same thing for me OK). With a pedal I can get away with any amp that can produce enough clean volume with good lowend authority and minimal EQ capabilities. That's why i never felt the need to spend past Peavey or Hartke, cheap yet loud and reliable. I can play with another band's bass amp easily this way or use one or both my TNT-150s, the only "stack" I'd take out on a gig these days.
