hello all, just joined this forum. i bought a used 5:50 about a year ago. the original purchase date was 2007. anyway when i engage the countor function there is a noticeable volume level increase as well as the scooped sound. And the further up i turn the contour up the more level boost i get as well as the eq scoop. Is this normal for all this amps, i've only played one other and it didn't seem to do it. The level increase is enough to make the footswitching ability of the contuor useless to me since the have to back off the amp volume if i engage it. Has anyone else experianced this? Otherwise i love the amp, just frustrated that i might not be getting all it has to offer. thanks
