Sire M7 Club

I did not return the M7. The quality of the preamp construction will always give me pause. However, the playability of the instrument is very good for me so I kept it.

Once I decided to keep it I gave it it's first proper setup. Prior to this there was not enough relief on the neck and B & E strings buzzed on the 3rd to 5th frets. I opened up the truss rod cover and loosened the strings. Seeing as I was not having to tighten the rod I gave it a slightly larger turn that I would normally. About a 1/3 turn was the distance that the hex wrench could turn without having to reset it. As it happens that was right on the money.

Set up was easy and with the extra frets I was able to test intonation at two octaves on each string. Now that I fixed its neck and back issues the M7 is much happier.
I would greatly prefer a truss rod adjustment at the base of the neck like on the other Sires, but the other plusses outweigh this one negative. If I don't like the preamp I'll probably replace it with an Audere.

I noticed that the truss rod cover was made of wood painted black. I wonder if I should sand the paint off and have a nice little spot of wood grain there instead? Tiny mod?

I find that there is more space up top to make a larger turn of the hex wrench on this M7 than there is on my other Jazz. That one needs a pick guard removed first (ugh) and then the adjustments would have to be in smaller increments because there is less room to turn. Then again, small truss adjustments are a good thing.

In my case the neck would have needed probably about two to three turns if the adjustment point was at the base of the neck. In my case with adjustment point on the top I was able to give one good, well over an eighth of a turn, to get the relief not only in the ballpark but pretty close to set.

Long story short: I found that I like the top access truss adjustment.
 
Just bought a used M7 and am trying to get it set up. I've got string buzz on the E-string at the 1st and around the 12th, but not on any other string.

Also, thin finish on the bridge, huh? Already scratched...
I had something similar on my E and B strings around the 3-6 frets. All the other strings were fine. In my case the relief was not very relief-iey so I loosened the truss rod about a 1/3 turn and let it sit for the rest of the night. Retensioned then tuned and the fret buzz was gone in my case. Hope it's a simple fix for you as well.

Regarding the bridge: When I set the bass up I didn't notice any scratches or issues on the bridge. I didn't seem to scratch the bridge setting it up. I have been more aware of that general area though because I am still concerned about those stacked pots and don't wnat anything to even breathe on them.

Congratulations on the new-to-you M7.

I recently bought this Sire M7 used on Reverb:

I really like how it sounds but nut slots too low and a possible minor ski jump made it super difficult to get the E-string low enough, so it's at a tech for now.
