The Seymour Duncan SFX-03 Twin Tube Classic is a premium, two-channel guitar preamp and overdrive pedal that features a 100% vacuum tube signal path. It is highly regarded for its ability to deliver authentic, high-voltage tube warmth and dynamic crunch to any guitar rig, making it especially popular for country, blues, classic rock, and surf music.

Key Features & Design

• Real Vacuum Tubes: Driven by a duet of military-spec, USA-made Phillips-Sylvania 6021 subminiature dual-triode tubes. These micro-tubes are soldered directly to the circuit board and are highly resistant to severe shock and vibration.
• High-Plate Voltage: Unlike "starved plate" tube pedals that run on low voltage just for show, the SFX-03 uses an internal high-voltage power supply to make the tubes truly cook. This results in massive dynamic range, uncompromised signal integrity, and authentic tube amp saturation.
• Dual-Channel Versatility: Features separate Rhythm and Lead channels, each equipped with its own dedicated Gain and Volume controls.
• Global Equalization: Features passive Bass and Treble tone knobs to sculpt your overall sound.
• True Bypass Circuitry: Ensures your guitar's natural, uncolored tone flows seamlessly when the pedal is turned off.
• Heavy-Duty Build: Housed in a massive, copper-finished heavy-duty steel chassis with an integrated fully-encapsulated toroidal transformer
