Seymour Duncan Bass Guitar pickups

The first effects pedal designed specifically to work together with the pickups in a guitar to achieve optimum gain and resonance for all tonal applications. Works with all musical styles.
By turning the gain control knob you can add pure, flat-EQ gain, ranging from 6dB to 25dB! The Resonance Switch drops the resonant peak of a single coil pickup up to 5KHz, making a single coil sound like a full and fat humbucker. Features fully discrete Class A circuitry along with true bypass. Comes in a heavy-duty steel chassis and runs on a single 9 volt battery.
For Resonance Switch to work properly, the SFX-01 must be first in the signal chain using passive pickups and a standard guitar cable -- not a wireless unit.

Production version of boutique fuzz pedal that features a six-position "Tweak" control for tonal versatility. Great for pop, classic rock, heavy rock, punk and metal.

The Tweak Fuzz features a six-position "Tweak" switch to voice the fuzz tone. This basic tone will be familiar to those who remember the rich, lush, vintage fuzz tones of the '60s pop festivals. But with the addition of the Tweak switch, the player can now create a myriad of totally unique fuzz tones, making the Tweak Fuzz an incredibly versatile pedal for electric guitar and bass. Discrete, Class A, low-noise transistor with true bypass. Steel chassis. Runs on a single 9 volt battery.

High-quality, two-channel, guitar preamp. Uses a duet of premium, mil-spec, subminiature, USA-made Phillips-Sylvania® 6021 dual triode tubes. Great for country, blues, surf, classic rock.

The high-plate voltage and 100% vacuum tube signal path allows the tubes to operate at their fullest potential and provide maximum dynamic range. The means you get the most gain and all the smooth tone you expect from a high-quality tube preamp. Two channels provide versatility. True bypass. Fully encapsulated toroidal transformer for quiet operation. Heavy duty steel chassis.

High-quality guitar preamp with built in boost. Uses a duet of premium, mil-spec, subminiature, USA-made Phillips-Sylvania 62051 pentode tubes. Great for old school metal, new metal, thrash, death and doom.

The high plate voltage and 100% vacuum tube signal path allow the tubes to operate at their fullest potential and provide maximum dynamic range. Additional gain is achieved with a high voltage, low noise, discrete Class A input stage. The solid state input stage increases the resistance of the stomp-box to microphonics. The result is maximum dynamic range, the most gain, and the heaviest tone your expect from a great tube preamp voiced for metal. Also features user-selectable 4dB or 8dB boost for pre-setting rhythm and lead levels. True bypass. Fully encapsulated toroidal transformer for quiet operation. Heavy duty steel chassis.

Mosfet distortion/overdrive with incredible dynamic range. Even at the highest gain settings, you can turn down your guitar's volume control and the Lava Box will clean up beautifully. Onstage, you can set the Lava Box for a loud lead tone and simply use your guitar's volume control to get your clean and crunch tones--all without switching channels or kicking in other effects. In the studio, you can explore the huge array of tones that are available with the intuitive controls, creating special-effect thin tones or spooky dark sounds that are perfect for layering and overdubs.

The six-position "Rumble" bass roll-off control changes the sonic character of the Lava Box's distortion for a huge range of tones, from bright and spanky to deep and warm. Whether you have the thinnest single-coil in the bridge of your guitar or the woolliest humbucker in the neck, there is a Rumble setting that's perfect for it.

Sonically pure, 100% analog signal path delivers the familiar lush, hypnotic, pulsing tremolo vibes characteristic of ‘50s tube amps. Digital tap control offers incredible control. Shape and Wave controls provide unparalleled versatility.

There are two modes. In Rate mode the tremolo speed varies continuously from one to 20 cycles per second. An LED pulses in time with the tremolo effect for easy Rate setting. In Ratio mode, the speed is established by tapping the Tap Rate switch, allowing for easy synchronization of the tremolo rate with the song tempo. Also, in Ratio mode, the tapped tempo can be expressed in your choice of four tap-to-note ratios: 1:1, 2:1, 3:1, or 4:1 (1/4 notes, 1/8 notes, triplets, or 1/16 notes).

The Wave control allows the tremolo effect to go from the smooth modulation of a sine wave through the sharper characteristics of a triangle wave to the abrupt on/off effect of square wave drive.

Most classic tremolos increase the volume over a certain period if time, say a quarter of a second, and then decrease the volume over a similar period of time. This gives a smooth, even feeling to the tremolo effect. When set to the middle of its range, the Shape Shifter’s Shape control does exactly that. But when the Shape control is rotated away from its center position, the relationship between the time spent increasing the volume and the time spent reducing the volume changes. For example, you can dial in one-tenth of a second of volume increase followed by four-tenths of a second of volume decrease, or vice-versa. This adds a very different feel to the tremolo effect. With quick swell and a slow drop, the effect is percussive like a piano. Conversely, with a slow swell and sudden drop, the result is reminiscent of a tape played backwards

As a guitarist, when you need power, it’s generally because you want to lay down chunky rhythms or you need to bust out a blazing solo. Enter the Power Grid, Seymour Duncan’s highest gain distortion pedal, which is designed to provide powerful overdrive and distortion suitable for all kinds of rhythm and lead playing, thanks to five stages of class A, discrete circuitry, which are cascaded to provide nearly 100dB of gain. Now that’s power!

But the Power Grid is not an untamed beast. All this raw horsepower is managed by a multi-element gain and volume control system that allows fine control. For example, if you crank the gain, you’ll get a very thick, saturated “Modded British” distortion, reminiscent of the big guitar sounds that defined metal. But if you back the gain off, you’ll get a very responsive “crunch” distortion similar to the Rhythm Channel on the SFX-03 Twin Tube Classic. And in between there are myriad levels of overdrive and distortion.

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.

While the Deja Vu includes the standard wet/dry blend control and the required delay time adjustment, the DejaVu also features an analog/digital blend control, to achieve any desired level of balance between the warmth of a real Bucket Brigade delay and the squeaky clean sound of a microprocessor-based digital delay. There's also a Feedback control, which allows you to dial in a runaway recycling of your sound in the style of an analog tape echo.
Also features two insert jacks. The Feedback Insert jack allows an external processor to be included in the recycling path, so that the processor's effect becomes more intense at each regeneration, thus continuously morphing the delayed sound as it recycles. The Wet output/loop jack works on the sound after it leaves the recycler, allowing custom tweaking of the overall character of the wet signal before it recombines with the dry signal.

The Deja Vu has Tap Tempo to match the delay time to the tempo of the music. And a Ratio Control that gives you multiple delays for each press of the Tap Tempo footswitch. And a tempo "Heartbeat" red flashing LED to keep everybody honest (or, at least, in time). And a "Modulation" control that lets you add a flange/chorus effect to the time delay.

Both insert jacks can connect directly to a standard volume pedal so the Regen Insert jack becomes a foot control for the level of regeneration, and the Wet Insert jack becomes a foot control for the Wet/Dry mix. And you can connect two foot pedals at the same time for ultimate control of the delayed sound.

Connect a second amp to the stereo output to hear an incredible, ethereal, space-filling stereo effect. Or use the stereo output by itself to get a sound with a totally different timbre.

High-quality, two-channel, guitar preamp voiced for the blues. Uses a duet of premium, mil-spec, subminiature, USA-made Phillips-SylvaniaB. 6111 dual triode tubes. Great for modern blues, Chicago blues, Texas blues, and classic rock.

Too often, inexpensive tube gear runs in "starved plate mode," where the tubes function like clipping diodes and do not actually amplify. The Twin Tube Blue's high-plate voltage and 100% vacuum tube signal path allows the tubes to operate at their fullest potential and provide maximum dynamic range. This means you get the most gain and all the smooth B-tone you expect from a high-quality tube preamp. Two channels provide versatility. Like all Seymour Duncan stompboxes, the Twin Tube Blue is true bypass and features a fully encapsulated toroidal transformer for quiet operation. Heavy duty steel chassis.
