The Optimist is a versatile overdrive pedal offering a wide range of drive levels. From punchy rhythm tones to delicate lead tones, the full range of drive is easily controlled. OD1 features a mid-bump circuit based on the popular Klon circuit, while OD2 features a flat-response overdrive. This allows for natural drive and clear boost. It also features a freely adjustable frequency EQ section, allowing for precise tone shaping to suit single coils or humbuckers.

User Voice: "The combination of OD1 and OD2 creates a great boost that really brings out the tone without being too harsh! The magic of EQ is that it creates a great balance between the single coil and humbucker." Corey Wong Notes: Drive Settings: The blend of OD1 and OD2 and the EQ settings can be tweaked to suit your acoustic environment and the type of guitar pickup you are using to get the best sound. Durability: Although the design is robust, care should be taken when placing and storing the pedals.Spec Product size: 127x69x68mm Product weight: 324g Input terminal: 1/4 TS PHONE (AUDIO), 1/4 TRS PHONE (MIDI) Input impedance: 1MΩ Output terminal: 1/4 TS PHONE Output impedance: 100kΩ Power supply/current consumption: DC9V (φ2.1mm center negative)/150mA (sold separately) Package size: 17x11x8.3cm Total weight (including packaging): 0.44kg Country of Origin: USA
