Owner’s Manual
SAFETY PRECAUTIONS:
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with dry cloth.
• Be sure use only properly rated power adaptors or universal power supplies (pedal board power supplies) with appropriate attention paid to proper voltage, amperage and ground schemes. Improper voltage/amperage being provided to the pedal may cause poor tone, inconsistent performance, damage to the unit, or all of the above. Proper voltage, amperage and grounding specs are supplied at the end of this manual.
• REPLACE THE BOTTOM LID after battery replacement before the unit is used. Some electronic parts inside are static sensitive and can be damaged from even a small static charge from contact with carpet or other conductive surfaces. DO NOT SET A POWERED
UNIT “CONTROLS UP” ON A METAL (or any) SUR-

FLUX-DRIVE™
The FLUX-DRIVE offers a gain range that is similar to
Mesa’s GRID SLAMMER™ - in that it’s still an overdrive – but it’s an Overdrive that goes farther up the gain-scale. It also offers the more complete Tone shaping network with individual TREBLE and BASS controls. This architecture makes the FLUX-DRIVE a more complete preamp that has versatility beyond that of the more classic Overdrive pedals.
Setting the FLUX-DRIVE’s GAIN control low, a region of subtle soft-clip threshold sounds are revealed. This smoothly transitions to a more aggressive, harmonic-rich middle zone that’s great for Classic Rock rhythm or Crunch.
At the upper end of the GAIN control real saturation begins.
The attack envelope gets rounder and more compressed creating a thick, harmonically rich landscape to solo in.
This region is waiting to propel your guitar to the forefront of a heavier mix and free you up… so your lead work can be inspired and memorable.
FEATURES & CONTROLS
IN:
This ¼” phono jack is the Instrument Input for the device. Plug the Output of your guitar into this jack with a shielded cable of good quality. The jack is a switching type jack and the circuit is turned on when a cable is inserted.
When the circuit is activated by inserting a cable, the internal battery is being used to power it – so be sure to unplug the cable from the INPUT when it’s not in use.
NOTE: The internal battery is switched to an “ON” state
(drawing voltage) by a switching element in the INPUT jack.
To prolong battery life, disconnect the cable from the ¼”
INPUT jack whenever the unit is not in use.
NOTE: If you wish to leave the INPUT connected permanently – as in a pedal board scenario – it is advisable to power the unit with an external 9V power supply. When an external (plug-in) AC 9-volt power supply is used to power the unit, the DC jack on the pedal automatically disconnects the battery to avoid battery wear and preserve its useful life.
If you are going to use external AC power either for long periods or permanently in a pedal board set-up, remove the internal battery to prevent (forgotten) battery corrosion.
roll-off, due to the added capacitance in longer lengths of cable. We recommend no more than 18-20 feet total (Input and Output combined) between your instrument and the termination at the INPUT of the amplifier. If you must use longer cable lengths, you might consider the use of a Buffer or Line Driver to keep the tonal integrity intact. While these change the sound slightly, it will usually be preferable to top end roll-off. And yes – those little 4” interconnects count too, so count them in your cable length.
LEVEL:
This is the master output level and it controls the amount of signal provided to the host amplifier. It can be used either to balance levels to compensate for high GAIN settings - so that no jump in level occurs when switched out of BYPASS. Another application is higher LEVEL settings to purposefully send a hotter signal to the host amp and “slam” the input stage for increased clip, drive or gain.
OUT:
This 1/4” phono jack is the OUTPUT for the device.
Connect the OUTPUT to the Input of your amplifier (or the
INPUT of the next device in line) with a shielded cable of good quality and of the shortest length possible.
NOTE: A Word on Cables… Always use shielded instrument cables of the best quality and shortest length possible when connecting these types of devices. This will minimize degradation of your sound, particularly high frequency
GAIN:
This control determines the amount of gain (overdrive) in the signal path.
Set low (8:00 – 10:30) it produces a range of subtle overdrive that’s soft and furry, yet featuring the classic midpunch associated with these types of circuits. This range is great for pushed and clip-threshold rhythm sounds and to add a slight bump for Blues solo sounds.
The middle range (10:30 – 1:30) offers the most useful region of gain that begins to saturate but still retains a dynamic punch that keeps notes expressive and tight. This works well for both Rhythm and Solo work across many styles of music.
The high range of the GAIN control (1:30 – 5:30) is all about smooth saturation. This region is most suited for single note soloing with its softer attack and more liquid response. It also has some applications for big crunch chording, but is not as harmonically complex in the top end as some pedals that are dedicated to higher gain styles.
BASS:
This control works in tandem with the TREBLE control to adjust low frequencies. Set low (7:30 – 12:00) the sound will be skinny, tight and percussive. The higher range (12:00 – 5:30) introduces rich, full low end that rounds out the sound and adds low-end thump. Heavier pick attack with higher BASS settings may produce a slower, less articulate feel as you “drag around” the extra lows.
TREBLE:
This control adjusts the amount of high frequencies present in the mix and – unlike devices with just a
TONE control - allows you to fine tune the high frequencies separately from the low frequencies. The TREBLE control makes up half of a more comprehensive tone control circuit that offers greater flexibility over the entire frequency spectrum. Set low (7:30 – 12:00) the sound will be darker, more rounded and seemingly compressed. The upper range of the TREBLE (12:00 – 5:30) brings in the cut, bite and more open top-end to create a sound that is bright, tight and aggressive.
AC POWER:
This standard female DC Receptacle on the pedal is the External Power Supply Jack and it accepts the male plug from a standard 9-Volt “wall-wart” AC power supply. When installing your unit into a pedal board utilizing a universal power supply (multi-output pedal board power
supplies), connect the external power source here. The internal battery is automatically disconnected by a switching element in the External DC Receptacle on the pedal.
However, if you know you will not be using battery power for an extended period – for example, if you are mounting the unit to your pedal board permanently - it is wise to remove the battery to avoid possible damage from long-term battery corrosion.
INTERNAL BATTERY:
This unit can operate on either a
9-Volt battery or a standard 9-Volt “wall-wart” power supply.
The unit is shipped from the Factory with a long-life 9-Volt
Battery to facilitate easier trial demonstration in a music store environment.
NOTE: The internal battery is switched to an “ON” state
(drawing voltage) by a switching element in the INPUT jack.
Disconnect the cable from the ¼” INPUT jack whenever the unit is not in use to prolong battery life.

BATTERY REPLACEMENT:
To access the 9-Volt battery for inspection, replacement or removal; make sure the
External Power jack is disconnected, remove the four Phillips- head screws from the four corners of the bottom lid and remove it, note the orientation/direction of the battery and terminals – and remove it. Replace if necessary.

Zinc type batteries, but you will have to decide what type best serves your needs.
