Seymour Duncan SFX-09 Double Back Compressor



Seymour Duncan

Finally a Compressor that doesn't squash your tone!


The gain control element is a VCA (voltage-controlled amplifier) which offers transparent gain reduction, consistent ratio, and predictable attack/release curves due to the faster response when compared with other compression methods like light and photocell. But perhaps what makes this compressor so unique is the Double Back feature which offers the option to blend back some uncompressed signal to restore some of the dynamics and "feel" lost during compression. There are three Double Back frequency options: "High" blends back top end only so sharp attack, and harmonics still come through. At low settings, tactile sensitivity is restored. Higher settings let you cut through the mix with amazing control. "Mid" blends back mid-range frequencies, perfect for fattening up your tone; and "Full" blends back the full frequency range to enrich overall dynamics.

The Double Back features a built-in, easy access battery door, a 100% analog signal path and true bypass.


Simply put, a compressor makes quiet passages louder and loud passages quieter. Most other compressors can get in the way of your guitar's natural transients and feel. Thanks to the innovative and unique Double Back feature and associated three-way EQ switch, the Double Back Compressor lets the original guitar signal leak back into the compressed tone for a natural performance like no other. The Double Back can also increase the clean sustain of your guitar, and it does this with almost no extraneous noise or interference thanks to revolutionary VCA circuit topology. This is the cleanest, quietest and most expressive compressor around.
