Ya I did and there's definetely an issue. I was throwing all this stuff that I was trying out there and got the feeling everyone thought I was crazy including KJ

, but compared the M6 directly with the SL900 and it was wayyyy louder at playing volumes. Probably a simple tube swap would suffice, but Jeff just said he would send a new one. Just a few more days again for that tone.

. Also I am happy with the GB CS and definitely not worried about the new one. Nothing is 100%, even with QC and it really is about how companies handle the ones that do make it to the end user and then have an issue. GB rules in this department...and there amps aren't bad either.
