New bass amp

I bought this secondhand Peavey TNT 160 from a bloke in Coolamon. It's got a lovely deep tone.

This is my first amp with an 18-inch speaker and the sound it produces wobbles my wobbly bits.

It's also got unusual features like this built-in crossover.

I'd guess the amp is 20-30 years old. I had a Peavey TNT bass amp in 1993 that was at least thirdhand. That was my first proper amp after four years of playing through five-watt guitar amps or putting the headstock against my cupboard doors.

Do you reckon I need to replace the scorpion?
