Details: Vintage Overdrive Pro VOP9 adds natural and warm nuance to your guitar sound like that of a good vintage amp. Specially designed circuit reacts precisely to every fingering or picking nuance with minimal compression. VOP9 combines functions of clean booster and overdrive. With Drive Control level set to minimum, the overdrive circuit works as a -12dB attenuator, and the clean boost circuit as a 6dB booster to create clean and flat boost sound. When turning up the drive level control, signal from overdrive circuit is blended in against clean signal until full overdrive tone is reached at Drive Control maximum level setting.
