PARADOX
TZF
THROUGH-ZERO-FLANGER
Features:
Bypass foot switch: True bypass with LED for both outputs A and B. Signal switching
done with audio relays.
TZF Polarity foot switch: Switches polarity of TZF signal. Dual color LED is red when
positive, and green when negative.Two very different, but essential TZF sounds, with
the ability to be switched during performance.
Positive TZF creates a very musical sweep when it crosses over the zero point. Think -
Brian May (Queen), Keep Yourself Alive. It's a very full sound with a fat low end.
Negative TZF is more intense and creates a deep cancellations as it crosses over the
zero point. With the right settings you can get it to become very thin and cancel out
completely. Think -Hendrix, House burning down. This mode has a hollow sound,
subtracting low end as it approaches the zero point.
Modulation control
Envelope takes the dynamics of your playing and turns it into a DC voltage which is
added to whatever you dialed in with the Manual control. This produces some of the
most incredible flanging sounds. All Modulation controls are highly interactive and can
yield flange sweeps never before created. With a distorted guitar, Env can be set to
produce unpredictable, erratic flanging sounds, very similar to an airplane flying over
you on a windy day.
Depth controls how wide the sweep is.Turn it down and the sweep goes away. This
allows flange control with Manual knob, Manual expression pedal, or Envelope control.

Maximum setting causes serious pitch bend. For wide sweeps, set at Depth at Max and
Speed at Min. Typical usable settings are between 9:00 and 3:00
Manual (with jack for pedal control). Controls a DC voltage that sets the base delay
time. Used for dialing in a custom sweep, and flanging manually. Also used in
conjunction with the Depth pot, setting the base delay time, affecting upper and lower
limits of the sweep. When using an expression pedal, the Manual knob can be used to
set where the TZF point occurs within the pedal's travel.
Speed (with jack for pedal control). When set below 11:00, it enters a much slower
speed range. Min -11:00 SLOW speed range. 11:00 -Max FAST speed range. When
using a speed pedal, the Speed knob sets the fastest speed limit.
Audio control:
TZF signal mix. Adds the TZF signal to the mix. When TZF and Modulated signal are
mixed, the TZF effect occurs.
MIX -Clean/Modulated delay. CCW-Modulated signal only. Can be used for vibrato
effects.CW-Clean only. Center -Even mix of modulation and dry. Dial in the mix you
want.
TZF polarity (LED and foot switch), Red = Positive summing, Green = Negative
summing. Foot switch selects between them.
Regeneration positive/negative mix. Adds resonance to the mix by providing positive
or negative feedback. Negative feedback is more prominent through output A, and
positive feedback is more prominent through output B. This regeneration feature is
calibrated NOT to self-oscillate. Distortion can occur at maximum settings when
excessive signal is applied.
Other: Stereo outputs (all true bypass using audio relays), 9 Volt AC operation, all-
analog bucket brigade delay (BBD) based flanging, compander based noise reduction,
Emphasis / de-emphasis noise reduction, easy glide action when controlling flange
manually -keeps the sweep "graceful" by ramping down.

TZF
THROUGH-ZERO-FLANGER
Examples
To start off, it's best to have some kind of distortion or overdrive BEFORE the flanger. This gives
TZF a more complex high mid and high frequency range to work with, accentuating the
cancellations. Straight guitar sounds nice, but wait until you master all the features before you
tackle it. The TZF effect really shines with an already overdriven or otherwise distorted guitar.
These samples are meant to give you some starting points. Try as many different combinations as
you can. It's important that you take some time to get and know Paradox TZF, it's unlike any other
flanger.
Example 1: Find the ZERO point
The first thing to do is to find the Zero point. Once you know where it is, you can start to
experiment. Try it first with negative TZF, TZF=GREEN. As you turn the MANUAL knob, you will find
that it cancels out as you reach the zero point (the Manual knob will be pointing towards the top
right corner of the box). You should be able to null out the signal. Now, hit the POLARITY switch,
and turn the MANUAL knob back and fourth, you'll notice that now it sweeps over the top without
canceling out. You have now experienced both Negative and Positive TZF, two very different
examples of TZF. Always experiment with different polarities!
Example 2: Manual control with expression pedal

Plug the pedal into the Manual jack. Floor the pedal. Now, rock it back and fourth and listen to the
sweep. Floor it again, and turn the MANUAL knob down to set where the Zero point is in the pedal's
sweep. Set it where you like it, and try both positive and negative TZF. If you're using a Foxrox
Expression Pedal, the Taper control will set the lowest point of the sweep and the Manual knob will
set the highest point of the sweep.
Example 3: Envelope control
Strum a chord and let it ring. You'll hear it sweep on it's own. It might sound erratic, and you'll
notice that it doesn't respond quickly like a typical Envelope filter pedal. This is intentional, fast
attack and decay just doesn't sound good with TZF. I'm going for strange and unpredictable
sounds.Tweak the ENV control to match your playing level. Try using distortion before the flanger.
Turning up the MANUAL knob will set the lowest point of the sweep. By tweaking the MANUAL knob
and the ENV knob, you can get some very intense, dynamic flanging sounds, and with some
practice you can manipulate the sweep to your liking. Turning the REGEN knob either way will alter
the way the ENV circuit behaves, because the ENV circuit gets it's source signal AFTER the REGEN
circuit. This will help you to get some erratic, gurgling jet plane type sounds.

Example 4: Stereo operation
In order to give a stereo image, some dry signal is dialed in. The flanging signal is out of phase
between OUT A and OUT B, giving a somewhat hollow sound, but the dry signal is in phase
between the two outputs. The combination of the two creates a wide stereo effect.
Example 5: Leslie/Chorus sound
Paradox TZF can get a pretty impressive Leslie type of sound. It's best in stereo. If you have two
amps, try experimenting with the Regen control. Turn it NEG, and it will show up more at OUT A.
Turn it POS, it shows up more at OUT B. Turning it to either extreme can cause distortion. It is pre-
set NOT to self-oscillate. If you plug in a Speed pedal, you can use the Speed knob to set the
MAXIMUM speed. Foxrox may soon offer a Ramp up / Ramp down box that plugs into the SPEED
jack.

You can use Manual, Width and ENV features all at the same time to create
totally unpredictable sounds. However, you should be aware that the flange point is controlled by a
voltage controlled oscillator. Feed it more voltage it goes up, feed it less, it goes down. The
envelope circuit adds voltage as you play harder. The Manual control adds voltage as you turn it
up, raising the flange point. Therefore, if you turn the Manual control up, the effects of the ENV
circuit will be less noticeable. Keep this in mind if you try using ENV and a speed pedal at the same
time.
Using the Foxrox Expression Pedal
The Foxrox Expression Pedal can be used to control:
1) CC2 Provibe SPEED and Paradox TZF SPEED
Set the SPEED knob at maximum. Back the pedal off all the way. Set the TAPER control right at the
point before it starts to speed up. Press the pedal all the way down and set the fastest speed you
want by setting the SPEED knob.
This will give an even speed increase throughout the pedal's travel. Tweak to your preference.
2) Paradox TZF MANUAL
Set the MANUAL at maximum. Back the pedal off all the way. Use the TAPER control to set the
lowest point in the pedal's sweep range. Turning it counter-clockwise will allow the lowest flange
point. Press the pedal all the way down and set the highest flanger point. Use the MANUAL knob to
set the highest point.
With TZF, you can use it to set where the ZERO point appears in the pedal's travel. I like to set it
so that the ZERO point kicks in at the 75% point, almost all the way down. That gives the right
range.
