Three of the most popular sustaining devices have been the eBow, the Sustainiac and the Fernandes Sustainer system. The eBow is hand held, while the other two are installed into a guitar. The Sustainiac and the Fernandes Sustainer system are considered the gold standard for onboard unlimited sustain, but, of course, such firepower comes at a hefty price. 

On the other hand, the eBow, which has been used on numerous recordings by everyone from Coldplay to U2, is far more affordable but surprisingly expensive. While that might sound contradictory, the fact is an eBow will run you close to a Benjamin.

Paul Riario has been the tech/gear editor and online video presence for Guitar World for over 25 years. Paul is one of the few gear editors who has actually played and owned nearly all the original gear that most guitarists wax poetically about, and has survived this long by knowing every useless musical tidbit of classic rock, new wave, hair metal, grunge, and alternative genres. When Paul is not riding his road bike at any given moment, he remains a working musician, playing in two bands called SuperTrans Am and Radio Nashville.
