Seymour Duncan’s SFX-03 Twin Tube Classic performs double-duty as a high-quality, 2-channel guitar preamp and stellar tube-driven overdrive. The Twin Tube Classic uses a duet of premium, mil-spec, subminiature, USA-made Phillips-Sylvania 6021 dual triode tubes, and generates a tone that’s great for country, blues, surf, and classic rock. The key to the SFX-03’s great sound is its ability to run high-plate voltage, allowing the tubes to really cook and create a thick, warm tone. Take your tone to new sonic heights with the SFX-03 Twin Tube Classic.
