How do I get my 7621 to Drop F?

thedrummerkid · 07-22-2012, 10:14 AM

Title really says it all.
I need string gauge advice.
Also, do I need to adjust the truss rod or anything on the guitar itself?
It is 100% stock.

Good luck getting the low strings intonated...I couldn't intonate the .058 low B on my 7621 because the saddle wouldn't move back far enough (even after removing the saddle spring that holds it in place when strings aren't on). I'm not sure what gauge you'd use for a low F, but I used a .064 for A and the tension was pretty comfortable (I like 10-58 in B, so think equal tension to that) so maybe .074 or .076?
Truss rod adjustment would depend on what gauge/tuning you're using now and what you're changing to (i.e., how much more/less tension there will be compared to how you have it set up right now). If you're coming from stock setup, there will probably be more tension in F and you'll need to tighten the truss rod. To check the neck relief (and see how much--if any--truss rod adjustment is necessary), look down the side of the neck (so you can see the entire side of the fretboard at once) after you change strings; if the neck is curved slightly up toward the strings, if means you need to loosen the truss rod (turn it a little to the left); likewise, if the neck is curved away from the strings, it means you need to tighten it (turn a little to the right). Some people like the neck to be slightly bowed away from the strings to raise action, but that can result in a bad setup and buzz, so try to get the neck perfectly straight if you can and do any action adjustments at the bridge. If you google how to adjust the truss rod, you'll find plenty of tutorials and videos of how to do it...

You'll probably need to widen the nut and drill out the tuners (or you can manually unwind the low F string each time you restring).

A 74 would be way too lose imo, I would start with an 82 at least and see how you like that...I'm not sure how much room those bridges have to intonate but I hope its a lot!

By turning the machine heads clockwise.

Sorry. J/k. Couldn't resist. But seriously, string gauge is totally a matter of preference. I'd start somewhere around .074. If the overall tension of the strings is roughly the same as before you won't need to adjust the truss rod. But even if you do it's nothing magical. It's just turning a screw. As long as you are careful everything will be fine.

74-80 string gauge.
Drill out the tuner to fit the new string gauge, adjust truss rod to compensate for the thicker strings (or you'll get buzz/stupidly high action because you've raised the bridge instead),possibly have to make the nut slots wider and get a short saddle so you can intonate properly.

Best of luck!

You could also get a short saddle from Graphtech for the low string so you can adjust it a bit better.

there is NO need to drill out a tuner, simply unwind the outer of the string instead and cut off where necessary. (may need a pair of snips just to catch the end of the string to begin unraveling the string

Thats literally the biggest pain in the ass ever though. Its pretty easy to drill out a tuner and its not like the 7621 has some sort of godlike expensive tuners anyways

arcadia fades · 07-22-2012, 04:08 PM

it takes 5 minutes at most, just an alternative if you haven't got access to a drill, but if you do, drill your heart out ! (made no sense) haha

BIG ND SWEATY · 07-22-2012, 04:10 PM

drilling out a tuner takes like 30 seconds

arcadia fades · 07-22-2012, 04:14 PM

yeah I know, i've had sperzels drilled out bigger before in the past done by a friend, takes no time at all, but I personally dont own a drill so, its not the end of the world for folks wanting to use thicker strings for their tuners that dont own a drill. Just saying
