The distance between the frets and the strings is referred to as the action. Low action (a small distance between strings and frets) makes the guitar easier and faster to play, since less force is required to press the string down to the fret. This is usually preferred by players with a delicate touch who are interested in speed. Players with a more aggressive approach often prefer the action a little higher, giving the strings more room to vibrate and increasing sustain. To adjust the action on a tremolo bridge, turn the bridge height adjustment screws in front of the bridge. It is not recommended to adjust the height of the individual saddles. They have been pre-set to match the radius of the fingerboard. Imprecise adjustment will leave the strings at different heights from the frets.

4. TUNERS: Intonation screws Most i2000 guitars come equipped with Sperzel locking tuners. To change strings, turn the flywheel at the bottom of the tuner in a counter-clockwise direction (when looking at the tuner from the bottom), this will release the string. Remove the old string and thread a new one through the bridge. Line the string hole of the tuner up so the string will pass through the middle of the hole. string hole shaft Pull the string until it is just taut. Hold the string taut with one nut hand and turn the wheel on the bottom of the tuner in a clockwise direction to hold the string. Tighten the wheel only until it is snug, over tightening can result in jamming the locking mechanism. After locking the string in place, tune to pitch and remove excess string. tuning key If the locking peg inside the tuner shaft gets stuck in the closed position, it can usually be freed by a firm tap on the top of the flywheel tuner with the plastic handle of a screwdriver. If this does not free the peg try pushing on the peg from both sides of the string hole with an ice pick or other pointed instrument, then try tapping the top again. To avoid the peg sticking, occasionally spray inside the string hole with a little silicone spray or WD-40. 5. TRUSS ROD: The truss rod controls the amount of bow in the neck, known as the neck relief. A small amount of bow is desirable to allow the strings to vibrate without rattling on the frets. Only very slight adjustments of the truss rod should ever be needed. Over adjusting can cause severe damage to the neck. With this in mind, it is recommended that truss rod adjustments only be made by a qualified technician.
