I have a second hand Peavey Nashville 400.
Serial number 4A-01955758.
How can I tell if it has the mod kit?

Nashville 400 amplifiers with serial numbers higher than 08575482 do not require the installation of this modification kit as this kit has been incorporated into the circuit at the factory. Serial numbers prior to the above are not modified.

The above information was obtained from: www.peavey.com

I think Ron doesn't know if the mod has been installed on his amp and is wanting to know what to look for so he can tell if the amp has already had the mod kit installed, i.e. a chip with a different part number, etc.

If you know of anyone who has a modified amp, you could try it out. There is a tremendous difference in tone quality and after you have used one you can easily tell the difference. To me an unmodified one sounds cold and hard, with a lot of mid sound, and one with a mod will sound full and vibrant, much more like a tube amp. If you wished to take the amp apart, you could probably be able to see that some of the resistors and capacitors had been resoldered as the solder will probably not be as shiny as the factory soldering.

Take it apart and look at the opamps (the 8 pin 'chips') If they're 4558's it most likely doesn't have the mod.

Thank you Bill Terry.
That is the question, and your answer helps. Now I know what to look for.

Is the mod for the nashville 400 something that someone with previous circuit board repair experience could eaaasily do themselves? About how much does the mod cost?

Brian, yep... bunch a thru-hole R's and C's and the op-amps, which are socketed. The kit comes with a board layout and schematic so it's a snap. The biggest hassle is getting the amp apart. Don't know about the cost... call Peavey, the service dept. is real hip.
