DI with three-band active EQ and Slap Contour switch for happy-slapping bassists.

While passive DIs proved to be quite useful for recording bass or sending bass to a console for live performance, people began to notice a decrease in overall response and punch. That's when active DI's came to the rescue. But how many are tailored to the response of a bass guitar? The Seymour Duncan SFX-06 Paranormal Bass EQ DI is, featuring a three-band active EQ that's optimized for bass along with a contour switch for slapping styles.

Seymour Duncan SFX-06 Paranormal Bass EQ DI, First Take:

  • Active DI with three-band EQ optimized for bass

  • Dedicated contour switch for slapping styles

  • Solid construction, balanced XLR out and ground lift

  • DI with active three-band EQ

    The three-band EQ allows you to dial in your tone in any room, sculpting your lows, mids, and highs quickly and easily. So, along with performing the normal functions of a DI, you get the benefit of adding an active EQ to your bass without having to make any modifications to your instrument. The EQ provides ±12dB boost and cut for each band, which have center frequencies at 30Hz for deep lows, 650Hz to contour the mids, and 5.2kHz for presence, clarity and attack.

    Proprietary Slap Contour switch for happy slapping

    The SFX-6 also features Seymour Duncan's proprietary Slap Contour switch, which applies an additional preset EQ curve. As the name implies, this is a dedicated switch for slapping styles, but it also adds an extra dimension to fingerstyle or pick playing. Slap Contour gives you a 6dB boost at 80Hz to bring out the bottom and cuts 6dB at 650Hz to reduce the mud that can occur in the low mids. The result is a solid low end and more room for attack. By using it with the 3-band EQ, you can bring out more attack information if needed, as well as extra bottom below 80Hz.
    Solid construction and hum elimination

    Built like a tank with a 16-guage steel chassis and powered by either a single 9V battery or a regulated DC power supply, the SFX-06 features a balanced XLR output with ground lift to eliminate electromagnetic interference and AC-hum. Between that and its active electronics you can drive longer cable runs to a feed a front-of-house mixing board or a recording console without noise or signal loss.

    • 1/4" input
    • Balanced XLR output with ground lift
    • 3-band EQ
    • Bypass footswitch
    • Slap Contour preset EQ footswitch
    • LED lights for both footswitches
    • 16-gauge steel chassis

    More flexible onstage and in the studio than your average DI, the SFX-06 is a must for every gig and session.

    • Gain Range: +/- 12dB
    • Input Impedance: 1MOhm
    • Output Impedance: 2KOhm
    • Maximum Output before Clipping: 2.6Vrms
    • Noise and Hum: -92dBV
    • THD at 1Vrms out at 1 KHz: 0.002 percent
    • Circuitry: FET Input OP-Amps with Discrete Gyrators
    • Power: DC 9 ” 12V; Battery or Regulated DC Adapter
    • Current Consumption: 2.9 mA Max
    • Dimensions: 5.50 x 5.20 x 2.20 inches
    • Weight: 1.9 Lbs
    • Chassis Material: 16 Gauge Steel
    • EQ Center Frequencies: Bass - 30Hz, Mid - 650Hz, Treble - 5.2KHz
    • Slap Contour Frequencies: +6dB at 80Hz, -6dB at 650Hz

    One DI box, multiple powerful voices

    By OneWebfoot

    from Bay Area, CA

    I've been gigging a passive bass (Barker 5-string Vertical) every week for over eight months straight, with additional rehearsals (total of 3-4 outings per week, every week). Church/worship venue. For most of this time, I cabled my bass directly to a small Genz-Benz combo, and from there to the in-house PA via XLR. I still don't recall how I got onto the idea of a DI box, or why my first "pedal" ended up being this Paranormal, but I've never looked back, and it makes a big difference. I've been using it two months now. The overall sound quality is better somehow, the sound guy gets a signal that lights up twice the lights as my old signal, and even the sound out of my tiny on-stage combo is better - more powerful and richer, and certainly more versatile (instantly). While the Slap Contour cuts mids by definition, and further sharpens my very low end, I end up using this box without slap contour most of the time as it can significantly enhance the richness of my mids without giving up low-end definition/sharpness.So this box gives me a very warm and versatile midrange, a VERY SHARPLY defined low end (so much so that I often use low B and C on my low B string very frequently now), and singing highs when I need to convey energy in songs otherwise dominated by the choir and piano. And it's no coincidence that people (other band members, people in the audience) started looking my direction and staring (in a positive way) the very first week I started using this thing. This single box has delivered a lot for me, and particularly when combined with Genz-Benz. Would buy again. I doubt anything could beat this box in its core mission.

    Great fix for bass tones.

    By ryankon518-Rwqkn

    I love this pedal. It fixes my tone on my peavy millennium 4 bass for recording. It had this weird fret noise that when I used this, just disappeared. Even if you don't have a prob with your bass this adds a great tone. Especially for slapping.

    Amazing pedal

    By Andy M

    from Charlotte, NC

    I bought this pedal about 2 weeks ago and I'm absolutely in love with it. It makes everything sound better. I play out of a fender american jazz bass, which works amazingly with this pedal due to its passive pickups. It makes going through house monitors way better since you have control over the eq. go to the seymour duncan website to see a video of what this pedal actually sounds like. Overall its a great buy.

    I have a fellow bass player who owns it, very nice tone hammering, and has a great slap contour...I will definitely get one of these little green monster.
