I'm always aware that a vintage bass might be in excellent condition because it was considered below average when played.
For me, a decent amount of play wear indicates a single, or a number of players have preferred to use it over the years.
Also, another benefit of a roadworn instrument is that new dings are stress free.
The Sterling Ball video linked above explains why that design came about. Although it looks like a modern 5 string version it's very different with the much longer alnico pole pieces used in pre EB Stingrays.
In general I am not a fan of passive tone stacks, much prefering active EQ sections. However, similar to the AD200, the TB sounds so good at close to flat settings, the EQ can stay where it is almost all the time.
I also wonder if the Orange 500 watt class D is perhaps under specified and delivers more than some other amps advertised as 500 watts? It wouldn't surprise me as Orange designed this unit specifically for bass amps.
I wonder if the 500 watt class D power amps are the same in these two heads? The Terror Bass v2 is Orange proprietary design using through hole ( i.e., no SMT) technology. I was surprised to see that when I opened mine (top photo), but it may make repairs slightly easier for techs without SMT capabilities.
