A unique concept in booster design, the DB10 features two completely independent boost circuits in a single compact housing. 

The Clean (Left) channel offers up to +20 dB of clean boost with a completely flat frequency response. 

The Vintage (Right) channel is Maxon’s take on the classic Treble Booster circuit.  It offers up to +20 dB of boost, but with a subtle high-frequency roll-off that increases as the Level is turned towards maximum.

DB10 Dual Booster

The original 1980’s PT-9 Phaser was a great pedal, but a little known fact is that Maxon also offered a different version of that model that was only sold in Japan under the Maxon brand – dubbed the PT-9 Pro, this silver-boxed rarity featured optical circuitry for a lush, drippy, 3D phasing effect similar to vintage units such as the Mu-Tron Phaser II and the Shin-Ei Uni-Vibe.

The PT-9 Pro+ Phaser takes this ultra-rare version of the PT-9 and adds a voltage-doubling IC to offer massive headroom and an improved frequency response, yielding fat, full-bodied phasing with incredible clarity and transparency.

PT9 Pro+ Phase Shifter

guitar world platinum award
The Nine Series Overdrive Pro+ takes Maxon’s classic OD-9 circuit and serves it up with two side orders of Whoop-Ass in the form of 9/18 volt operation and a Mid Boost switch.

In 9-volt setting the Pro+ sounds and functions like the standard OD-9 with the added option of a healthy +3 dB of midrange boost at approximately 800 Hz (actual frequency is dependent on Control settings) – great for cutting through a band during solos.
When set to 18-volts the OD-9 Pro+ becomes an 800-pound Gorilla, offering up beefier lows, tighter saturation, improved dynamics and a chunky, aggressive pick attack that will make your amp sound and feel like it just took a Viagra.  Switch on the Mid Boost in this mode and let your solos breathe fire.

Don’t just play like the pros – play with the Pro Plus.
