Attenuater switch on 400rb.

What do you use it for - is it for active basses?

Really hot ones ... when you are getting unwanted distortion and can't clean it up by lowering the input gain. However, many active basses are running close to unity gain and shouldn't cause a problem. I've had an 800RB for over 20 years and have never needed to pad the input. YMMV.

Thanks for that, i had some slight distortion using a pedulla thunderbass so use the attenuator, but i might trial leaving it out again and see how it sounds - theres nothing about using it for active basses in the manual.

It cuts the strength of the signal coming in the front end of the amp. On some amps from other companies it's labelled active and passive but from experience I say always use the passive or high gain or hottest, not - anything input and tweak from there. It's possible you may need to pad the input if the sound is just too ratty or the entire sweep of your volume max and minimum is between 1 and 3 on the dial but in a lot of cases it isn't neccesary even on a lot of active basses.

Don't have any hands on experience with your bass though.

Hint: There's no law that says the volume on your bass has to be on 10 either, some sound better on 7 or 8.

Excellent information, cheers, i'll run it without the pad next gig and go from there.
