I posted in here a while back when I got my 4HH in Charging Green. I played it out for a month of gigs and then the GAS returned and I bought one of the new Fender Player P basses. I still want the Ray to be my #1 but I didn’t have a P in my collection. Now I can’t put the P down, and all of a sudden I’m noticing horrible fret buzz from the Ray. I’m inexperienced with setups but out of the box I needed to lower the action on the EBMM whereas the P bass felt perfect out of the box. I’ve watched a bunch of videos and got an action ruler and have tweaked the truss rod and bridge saddles to get it to match (as closely as I can) the settings of the P bass. Is there a chance I got a dud? Or is it my I experienced hands? I can’t seem to get the buzz out of the E string from about the 6th fret up.
I really like the setup guide posted in the FAQs for bass setup on the EBMM site: FAQ | Ernie Ball Music Man
I would check the neck bow first (I like the business card 'rule of thumb'), seems like if there is buzz in the middle of your neck there might be too much relief and could stand to be tightened up a bit. Once that is set, I usually visit the saddle heights and get them just high enough to where i'm not getting any buzzing playing high up on the neck around the 14th-16th fret-ish. Lastly, I've learned not to (mis)underestimate the power of getting the saddle intonation just right. Getting that string to vibrate at the perfect wavelength is just about everything.
That's my experience so far fooling around with the 'Ray. These other folks on here know a whole bunch more than me, though.
