This weekend I pulled the bright switch on my nashville 400 out and turned the hi and presence control down and it seemed a got a cleaner sound I read somewhere once that on some of the fender amps that had a bright switch that that when it was on the amp was actually in its normall mode and when the switch was turned off some of the hi end was rolled off using a capacitor, just wondered if anyone out there was using the amp with the bright switch out

Jeff,

Concerning the Fender amps, it is actually just the opposite. The bright switch increased the response of the amp 10 fold when it comes to ever higher audio frequencies. Let me explain:

What Leo had his engineers do is; UNLESS the volume was at maximum, the highest frequencies went thru UN attenuated. In other words as you decreased the volume from 10 ever closer to 0, the mid and low frequencies would be attenuated. But the highs would remain unaltered.

This caused an ever more piercing treble to come out of the speaker the closer the volume control was to the 0 setting. Of course IF you ran the control at 10 then the brightness switch, for all practical purpose, was innafective.

I use the bright switch on my NV400 also. I just like the sound.

I use the bright switch as well. It took some time to get used to it but when I push it back in I feel like I lose the clean sound I had. If it works for you and sounds good to your ear that is what counts.
