The Virtual Acoustic uses the same technology as the Virtual Vintage line to create a pickup that's practically noise-free, even in comparison to humbuckers (patent applied for). The sound is very accurate, reproducing the natural dynamics and tonality of an acoustic instrument and enabling the Virtual Acoustic to capture the character of the particular guitar it's mounted in. It installs easily in any round-hole steel string guitar. It's also got a volume control with a compensated tone network to minimize tone changes when the volume is adjusted.Recommended for Soundhole in all steel-string guitars.Tech TalkWhen you plug the Virtual Acoustic into an amp with all the tone controls set flat, the sound is very even. But adjusting the controls, particularly on a good acoustic amp, gets dramatic results. Highs sizzle, lows open up. If you're going to combine it with a piezo bridge pickup, DiMarzio recommends using a phase-switch equipped preamp or mixer to achieve correct phase relationship and separation.
