What are these settings on a Peavey Nashville 400?

Very humbly, I need an intro course to this amp.

The picture shows everything that has me stumped. I’ve read some definitions of what these things are in general, but I thought I could get some better clarity from the steel community.

Better yet, those of you who play through these, what are your go-to settings?

Go to the Peavey Electronics website and do a search for user manuals. The NV400 manual will explain all of the controls as well as give some sample settings.

Post gain is like a master volume control. Pre gain controls the volume of the preamp signal going to the power amp. The post gain should be higher than pre gain to minimize distortion. I run my post gain all the way up (for gigs) and control the overall volume with the pre gain.

The shift control centers on a midrange frequency. Most folks I know put it at 800 (hertz). The mid control now determines how much that frequency is cut or boosted. I set my shift at 800 and the mid at about -6.

Presence is a high-high frequency tone control.

The switch you are pointing to is a ground switch. On old tube amps like Fenders, the ground switch would be used to try to stop hum and to stop getting shocked if you touched your guitar strings and a microphone at the same time. OUCH! I find the NV400 ground switch to be totally useless, but I don't sing and don't have the possibility of touching strings and mic together. That may be a use for the switch though.

Hey, thanks for the walkthrough! This is really helpful. Now I am tempted to set up a mic and see if that is what happens. It might be worth the shock

Thanks for the tip! I did find this manual. https://assets.peavey.com/literature/ma ... 370379.pdf

It does explain things, and it's helpful to have it in lay terms as well.

Ooops ... I missed the "you found it" DOH!

The settings labeled NASH were the settings Jeff Newman used in 1982.
