Hi all, my princeton chorus amp is giving me some problems. It’s very noisy when I turn it on and it’s sound is not as loud as normally. Does anybody have schematics for this amp or can give me any useful hints how to get it ? Thanks in advance.

when in overdrive mode the hum from your pickups is amplified a lot. This happens with all amps. A good way to cancel all hum is to install a good humbucker in your guitar. If your guitar cant take a humbucker you can always buy single coil sized humbuckers (seymour duncan makes a lot of those). Also some cables like expensive Monster cables help cancel hum.

Try to find out if the guitar/amp are having a good earth connection. : Hi all, : my princeton chorus amp is giving me some problems. : In the overdrive mode it is very noisy. : Does anybody have schematics for this amp or can give me any useful hints how to get it ? : Thanks in advance.
