Jackson Audio | BROKEN ARROW | Level Matching Dynamic Overdrive, EQ & Gain Cycle
or 4 fortnight payments of $104.75 AUD with More info
The BROKEN ARROW is a very flexible overdrive with 4 presets for clipping options, an innovative gain adjustment feature that we call GAIN CYCLE, and a 3 band active EQ for maximum tonal flexibility.
To top it off, a boost circuit was added which is the same type of MOSFET boost circuit found on our top selling PRISM Preamp pedal.
The boost circuit is in its own true bypass loop which means it can be used independently of the DRIVE circuit. The boost circuit in the BROKEN ARROW is a MOSFET based boost much like the AMP MODE found in our best selling PRISM Preamp pedal. With 4 different BOOST presets are available, each preset is EQ’d slightly differently to allow it to alter how it interacts with the overdrive circuit
Preset 1 – YELLOW LED: Bright Boost. Very useful for creating a thinner sound or when boosting a thick sounding overdrive.
Preset 2 – GREEN LED: Mid Boost. Not as thin as the yellow mode, the green mode allows more lows and takes on the character of a mid boost.
Preset 3 – AQUA LED: Tailored Boost. Most people will find this a perfect setting that will complement most any overdrive setting in the BROKEN ARROW.
Preset 4 – BLUE LED: Full Range. No tonal colouring here! Just your guitars natural tone!
To select a boost preset, press and hold the BOOST footswitch for more than 1 second and boost program mode will become active.
Note: When boost programming mode is exited, the selected boost preset is written to the internal EEPROM on the microprocessor and that will become your default boost setting when the boost is engaged even after you power cycle the BROKEN ARROW.
STND BOOST – Our version of the MOSFET boost. Same tone, no noise.
ALT BOOST – Modified version of the MOSFET boost. Same tone, slightly more gain, crackles when you turn the knob.
The BROKEN ARROW allows for 4 different presets of clipping diodes which themselves drastically alter the tone and feel of the way the overdrive clips and distorts.
Preset 1 – GREEN: Classic Screamer. Two symmetrical silicon diodes give the classic drive and compression that the Tube Screamer is known for.
Preset 2 – MAGENTA: Asymmetric Clipping. Three asymmetric silicon diodes will clip the top and bottom portions of your guitars waveform differently resulting in a more complex and interesting tone. This sounds great when laying down aggressive rhythm parts!
Preset 3 – BLUE: Symmetrical Clipping. Four symmetric silicon diodes will clip the top and bottom portions of your guitars waveform evenly which gives a more focused and direct tone. One notable pedal that uses this style of clipping is the Timmy.
Preset 4 – AMBER: Vintage Marshall. Two RED LED’s are used to symmetrically clip the top and bottom portions of your guitars waveform evenly. The LED’s allow MUCH higher headroom so your tone will stay more open and less compressed much like a vintage Marshall.
GAIN CYCLE takes the GAIN knob setting, which selects your maximum gain, and divides that level of gain into 4 equal parts. Say for instance you have your GAIN knob set at the maximum setting or in other words, 100% gain. Every time you press both footswitches simultaneously, the gain of the pedal will jump up 25% until you get to 100%. The following press after 100% will cause the gain cycle to start again at 25%.
TIP: Add the BOOST to push the overdrive even harder for endless sustain!
It’s important to remember that GAIN CYCLE setting #4 (100%) will be as much gain as you have the GAIN knob set for. Think of the GAIN knob on the BROKEN ARROW as your maximum gain with each GAIN CYCLE setting being a percentage of that maximum value.
The brightness of the DRIVE led will change to let you know which percentage of gain you have selected. The higher the percentage, the brighter the DRIVE led.
3-BAND ACTIVE EQ
Based on the legendary Baxandall EQ that is featured in countless studio EQ’s, the BROKEN ARROW EQ takes this circuit and tailors it for guitarists! We spent tons of time on this EQ dialing it in so it would hit all the frequencies that guitarists need to adjust, and then sweetened it by removing the ear fatiguing highs and lows that can appear at extreme settings.
