: Hi Bass Enthusiasts!

: I am new to bass, just started. I bought an Ibanez bass, a Soundgear, which I got a great deal on, and am very happy with as my first bass. (Small hands!!) However, I have noticed that the action on the strings varies from the top of the neck to the bottom... The action at the bottom is pretty high, and being a beginner with weakish fingers at this point, it hurts my hand. When I stand my bass up and look sideways at it, I can see the strings kind of slanting away from the neck as they go down towards the bridge.

: SO....Is there a way I can adjust the neck back about 5-7 degrees so the action at the bottom is the same as at the top? (I've looked at the way the strings leave the bridge and I don't think I can take them down anymore on that end because they are close enough to the pickups already.) BTW - The neck is a bolt-on.

: Another question I need help with - someone told me in passing I need to adjust the bridge so I can tune with harmonics. I have tried this, but I can't get it to work, so I think this person may be right. Any idea how to do this? Is there a book that would describe all this?

: Thanks for your help!!

Hey there Kyla,
Both neck relief and bridge intonation adjustments can be done quickly and cheap by any reasonably experiencied technician in any guitar store, but if you're unable or unwilling to spend that time and money, they are (fortunately) easy enough to do them yourself.
To adjust the neck relief: in the headstock of your bass there has to be a cavity (most likely protected by a plastic cover) to access the truss rod. So unscrew that cover, get an allen wrench that fits the rod and adjust the rod with a colckwise motion of the wrench. Take it easy with the adjustments, though,and don't overdo it. Try a fraction of a turn at a time and let the bass alone for a day or so to see how the wood reacts. If it's enough, you're there; if it isn't, try the same procedure again.
To adjust intonation at the bridge: plug into an electronic tuner and play harmonics at the 12th fret of every string, then adjust the tuning machines to make sure the strings are perfectly in tune. When you actually fret the notes at the same 12th fret, you should get the same note as when you played the harmonic. If you don't, then you need to adjust the bridge saddles with a screwdriver from the bottom of the bridge. If the fretted notes are sharp relative to the harmics, move the bridge saddle towards the pickups; if the fretted notes are flat relative to the harmonics, move the bridge saddles towards the instrument's butt.
Hope this helped. Buena suerte and keep your bass up front in the mix,

El Pájaro
