i have a $1500 bass amp im using for electric guitar. is there any way i can get any effects, overdrive, reverb, or distortion out of it. it has treble nobs and bass nobs and boost nobs and everything else but no effects nob!
"everything happens for a reason"
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.
