Problems with my amp.

i'll guess that your tuner is prone to picking up radio interference.
does your amp have a tuner out jack?
if not, does it have an effects send jack and are you not using the effects loop?
or doesn it have a line out jack you're not using?
the idea is if the tuner is picking up radio junk, you'll want it out of your signal path. to do this without having to unplug from the amp every time you want to tune, you'll have to run a line to the tuner from the amp's tuner out or another output like an effects send or lineout.

now, you're probably going to say "i dont want to do that becase i want to be able to mute the amp with the mute button on the tuner when i'm tuning". and i'll say "sorry, but it looks like your tuner isnt as quiet as the advertising hype said it would be"

or, if you're lucky your basement has much more radio signals than the rest of the world.

 

Hi Brad, I agree with IvanMike, look for a "tuner out" jack on your amp. Running the tunerr "inline" through your audio path is just asking for trouble.

If you don't have a "tuner out" jack on your amp, there are several ways to go. One is, you can create a poor man's "line out" from your speaker (cab), with just a couple of resistors and about sixty seconds with a soldering iron.

Another way is, if you have an "effects send" on your amp, you can use that to feed the tuner. Sometimes, that jack will disconnect your preamp (although usually it's the effects "return" that does that), but if that happens, try pulling out the plug halfway, sometimes if you position it just right you can tap the signal without disconnecting the pre.

And finally, there's always the old "splitter box", if you're willing to spend a hundred bucks or so.
