Features Thank you for selecting the ZOOM Ultra Fuzz UF-01 (hereafter simply called the "UF-01"). The UF-01 is a high-performance compact fuzz unit developed with input from top-level professional musicians the worldwide. It reflects ZOOM's rich expertise with analog circuitry and has many attractive features. ◆ Ultimate fuzz for devastating sound To design the UF-01, ZOOM first analyzed the elements of fuzz sound created by cutting-edge musicians.
◆ Innovative play with noise The UF-01 also provides a GATE control that adjusts the sensitivity of the internal noise gate. With this, you can cut unwanted noise during play pauses. By setting the sensitivity purposely on the high side, you can also create a wild attack sound. Another great asset is the RESO control that results in an oscillation peak at a certain frequency. Use it to achieve fierce feedback or even to emulate the sound of the legendary theremin.
Parts and Functions This section explains the various parts of the UF-01.
1 GAIN control This control adjusts the fuzz gain. Turning the control clockwise increases the distortion intensity. 2 GATE control This control adjusts the gate sensitivity. Turning the control clockwise causes the gate to open only when the level exceeds a certain threshold. Turning the control all the way to the left disables the effect. For details, see page 9. 3 COLOR control This control adjusts the fuzz sound character.
Connections This section explains how to connect the UF-01. Open cover of battery compartment and insert battery 1 2 Turn amplifier off and connect cable to guitar Make sure to insert the battery to the connector with correct polarity. Make sure that the plug is inserted fully into the OUT jack of the guitar. 3 Insert the cable from the guitar into the IN jack of the UF-01. This turns the UF-01 on.
4 Connect cable to OUT jack of UF-01 Connect another cable to the OUT jack of the UF-01. Make sure that the plug is inserted firmly. 6 Turn amplifier on and raise volume Turn power to the amplifier on, and adjust the volume to a suitable level, using the controls in the following sequence. (1) Volume control on guitar (2) LEVEL control on UF-01 (3) Volume control on amplifier 5 Connect output cable to amplifier Make sure that the amplifier is turned off and the volume is turned down.
Sample Settings This section shows some actual setting examples. ■ Boomy vintage fuzz MIN MAX Meet the king of fuzz sounds. By turning the TONE control further to the left, you can get a mighty, earth-shaking tone. This is great for lead solos and low-end riffs. MIN MAX ■ Tight vintage fuzz MIN This sixties style tight sounding fuzz stays well defined also when playing chords, which is suitable for chord backing as well.
■ Using the GATE control To cut noise during play pauses, proceed as follows. Without playing your instrument, turn the GATE control fully to the left and then slowly raise it to the point where noise stops. By turning the control further to the right, you can obtain a special low-fi sound with crackling at the noise threshold. 3 2 ■ Using the RESO control 1 Turn the GAIN control close to the maximum position. With lower settings, oscillation may not occur.
Connection Examples With Compact Effects This section shows setting examples for using the UF-01 together with other compact effect devices. ■ Combination with pedal wah GAIN 7 GATE 0 COLOR 5 RESO 0 TONE 4 ■ Combination with flanger GAIN 10 GATE 0 COLOR 10 RESO 0 TONE 4 DEPTH RATE FEEDBACK 5 2 5 FLANGER 10 ZOOM Ultra Fuzz UF-01 This is a combination in the style of the golden sixties. Basically, the pedal wah can be inserted either before or after the UF-01.
Connection Examples With Multi-Effects This section shows how to use the UF-01 together with multi-effect devices such as the ZOOM GFX-4 or GFX-8. ■ Connecting UF-01 before multi-effect device ■ Using send/return loop of multi-effect SEND RETURN In this example, the connection sequence is UF-01 → multi-effect → amplifier. Distortion is produced by the UF-01, and distortion effects of the multi-effect device are bypassed.
Troubleshooting If there seems to be a problem with the unit, check the following points first. ◆No sound. ● Are connections to the IN and OUT jacks reversed? Check the connections. ● noise and hum picked up by the pickup is reinforced. If noise during play pauses is a problem, turn down the GAIN control (or turn up the GATE control). ● Is the battery exhausted? Low-quality cables can cause noise. Use a short, good-quality cable. Insert a fresh battery.
◆Battery gets used up very quickly. ● Is a plug inserted in the IN jack? Power to the UF-01 gets turned on when a plug is inserted in the IN jack. In this condition, current is drawn from the battery regardless of whether the effect is switched on or off. When not using the unit, be sure to disconnect the plug from the IN jack.

Usage Precautions ■ Electrical interference For safety considerations, the UF-01 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the UF-01, as the possibility of interference cannot be ruled out entirely. ■ Cleaning Use a soft, dry cloth to clean the UF-01.
Safety Precautions • If batteries leakage has occurred, wipe the battery compartment and the battery terminals carefully to remove all remnants of battery fluid. • While using the unit, the battery compartment cover should be closed.
