The ebow（能量弓），是一个小型的手持设备，弓的弦吉他使用电磁场。它产生一个独特的吉他声音，以非常缓慢的攻击和无限维持。玩的大族激光、吉他手握过的字符串，在拾取或孔，使串坐在下面的小缺口的大族激光。的大族激光的磁铁使弦振动直到反馈本身在其自己的共振频率。这种反馈回路非常类似于著名的放大器反馈，但更可控版本。玩家可以改变声音的响度移动更接近或更远的字符串，如放大器的反馈。的大族激光是从低功耗模式切换到高功率模式，提供了一个强有力的，丰富和谐的声音。
The ebow已用于在同一时间或其他的几乎每一个吉他手在阳光下：Tom Petty，Dave Gilmour，乐队，Sigur Ros，宁，酷玩，碎南瓜，治愈，REM，U2，等等。
The ebow ( Energy bow), is a small, hand held device that ‘bows’ the strings of a guitar using an electromagnetic field. It produces a unique guitar sound, with a very slow attack and infinite sustain. To play the ebow, the guitarist holds it over the string, near the pickup or hole, so that the string sits in a small notch on the underside of the eBow. The eBow’s magnets then cause the string to vibrate until it feeds back on itself at its own resonant frequency. This feedback loop is very similar to the well-known amplifier feedback, but a much more controllable version. The player can vary the loudness of the sound by moving closer or further away from the string, as with amplifier feedback. The ebow is switchable from low power mode to high power mode, which gives a strong, harmonically rich sound.
The ebow has been used at one time or another by nearly every guitarist under the sun : Radiohead, Tom Petty, Dave Gilmour, Sigur Ros, NIN, Coldplay, Smashing Pumpkins, The Cure, REM, U2, etc etc…
Creating The Sampled eBow Instrument
We wanted to capture the sound of the ebow for all those non-guitar players out there, or perhaps guitarists who have had problems using it with an acoustic guitar! Two guitars were painstakingly sampled, an acoustic and an electric. Both were sampled with the high and low power ebow setting, with vibrato and then again without vibrato. Several note off samples were recorded for every note, to make the instrument’s response as detailed and lifelike as possible. The level of the note-off sounds can be mixed to taste by the user. The acoustic was recorded in full stereo to give a natural, spacious image. The electric was recorded mono D.I for use with amp simulators or for re-amping.
The high and low power setting can be cross-faded using the mod-wheel -a very expressive effect not possible with a physical ebow! The vibrato samples can be selected using a keyswitch on keys B5/C6 .
