why would any amp that is $1500 have built in effects other than reverb or tremelo (for guitar) or compressor (for bass)?

If it is a SS state bass amp with no gain knob, chances are there is going to be no overdrive available to you, and if it's really $1500 then there is probably enough headroom that you will never run out of perfectly clean sound in a gigging situation.

If you want overdrive of any level, trade it in for a guitar amp, tube bass amp, or bass amp with overdrive channel, or buy some pedals.
