Designed for both guitar and bass, the XO splits your signal into high and low frequency bands, which

are sent to two independent effects loops. This means that you can apply separate effects to the high

and low frequency portions of your signal, or even send them to two different amps.

Whether you want to restrict a particular effect to just one part of the frequency spectrum – fuzz on just

the lows, for example, or reverb on just the highs – or combine different effects on the two bands at the

same time, the XO opens up a whole host of creative possibilities.

And for bass guitar, the ability to apply effects to the mid and high frequencies while leaving the lows

untouched effectively means that no guitar pedal is off-limits.

More detail:

The XO is built around a pair of active, 12dB/octave filters – one high-pass, one low-pass – arranged into

what is known as a crossover.

The XO’s real power comes from the Crossover Frequency control, which lets you move the dividing

point between the high and low bands up and down the frequency spectrum. The Range switch toggles

between frequency ranges designed to suit guitar (300Hz to 3.4kHz) and bass (50Hz to 600Hz).

You can use the XO’s high and low send-return loops one at a time, adding modulation to just the lower

portion of the signal, for example, or distorting just the highs while leaving the rest of the signal clean. Or

you can combine two effects at once – a warm delay on the lows and a shimmering reverb on the highs,

for example, or even twin delay or modulation effects set at different speeds.

The pedal also features a Return Balance control, which adjusts the relative level of the two return

signals. With nothing plugged into the two effects loops, this control effectively turns the XO into a tilt EQ,

increasing the level of the low band while decreasing the level of the high band or vice versa. Unlike most

tilt EQs, however, here you can move the centre frequency up or down.

The XO also features a global dry blend control to adjust the overall wet/dry mix, a phase switch that puts

the high and low bands out of phase, and a handy button to swap the high and low sends over so you

can hear what the effects you’ve connected sounds like on the other half of the signal without having to

unplug and re-patch anything.

CONTROLS

CROSSOVER FREQ: Moves the centre frequency of the crossover – the point at which the signal is split

into high and low bands – up or down the frequency spectrum. Everything above the centre frequency

goes to the high send. Everything below goes to the low send.

RANGE: Sets the range of the Crossover Freq control to suit guitar or bass. Push switch down for bass

(50Hz to 600Hz) and up for guitar (300Hz to 3.4kHz).

PHASE: Press down to put the high and low bands out of phase. Can be used for creative effect or to

prevent phase cancellation if the high and low bands end up out of phase following processing.

 

SEND FLIP: Swaps the high and low sends over. With the switch down, the high band is routed to the

low send and the low band is routed to the high send. This allows you to instantly swap over the effects

placed in the two send/return loops without having to re-patch any cables.

RETURN BALANCE: Adjusts the relative level of the two effects returns, allowing you to adjust for any

changes in level created by the effects you are using. When no effects are in use, the Return Balance

control acts like a tilt EQ, emphasising the high or low band.

DRY BLEND: Sets the overall wet/dry mix. Turn clockwise to mix in the pre-send dry signal with the

effected signal.
