 A combination clean booster and overdrive in one, the OD820 uses a dual pot to blend clean and saturated signals for a more transparent, less compressed tone. More importantly, the OD820’s entire circuit runs at 18 volts using an ingenious voltage-doubling circuit that offers more accurate, full-frequency note reproduction and improved dynamic response. The result: An overdrive that is dangerous in the hands of a gifted guitarist. Unfortunately, most of these attributes were overlooked by the masses and the music press alike, who erroneously labeled the OD820 as a larger, pricier 808 and basically ignored it. Sometimes greatness has to be thrust upon you. With this in mind, Maxon has decided to reintroduce the OD820 to the world in the form of the VOP-9 Vintage Overdrive Pro. The VOP-9 takes the same basic circuit as the OD820 and offers it up in Maxon’s indestructible, industry-standard 9-Series chassis. It uses the same JRC NJM4558D op-amp for low-noise operation, and features the same negative feedback loop clipping diode as the OD820 and OD-9. Like the ‘820, the VOP-9 also features mechanical true bypass switching for uncolored sound in bypass and the ability to blend clean and overdriven tones together. In addition, the VOP-9’s operating voltage is switchable between 9 and 18 volts via an internal DIP switch accessible through the unit’s battery compartment. Running at 18 volts eliminates unintentional distortion from the use of high-output pickups and electronics, even when the guitar is played at full volume and the VOP-9’s Drive control is set to full. This feature basically makes the VOP-9 a “4 in 1” pedal, offering clean boost or overdrive functions at 9 or 18 volt operation, allowing the user to find the setting that works best for their particular setup and playing style. When you’re ready for greatness, the new Maxon Vintage Overdrive Pro is ready for you! |
