Thats all i can afford , but i didnt like the distortion because it sounds like it has too much gain , my question is can you turn down the gain ? and the noise supressor , its always on ?
There should be an EQ for the gain on the distortion settings.
I know there's an EQ for it overall.

If you can, try downloading a PDF version of the instruction manual. It should have a lot of info there.
Signatures are overrated.
