G-Force warnings and precautions

Dangerous operations

The Tuner mute

In older software versions the Tuner mute may stop working in the following circumstances:

• When you turn the Input level wheel on the front, the Tuner mute stops working as long as the display shows the message "Input level range changed".
• If you hit the Tempo button while already using the Tuner, the Tuner mute stops working until the tap tempo sequence has finished, after which it will kick in again. Since the Tempo button is located immideately below the Tuner button it can easily be hit by mistake.

The Pitch Shift block

When using very low Pitch Voices values in the Pitch Shift block (around -1200 cent or lower) together with high Feedback values (75% or more), subsonic bass sounds are produced that can damage speakers. Being subsonic you cannot hear them, but they will show up on a level meter. High pitch voices are not dangerous in this way.

Precautions

• Don't leave a memory card in its slot where it protrudes and can easily become damaged.
• Most electronic music equipment, including the G-Force, send out voltage spikes through their output jacks when switched on or off. Since these spikes may damage power amps and speakers, always turn on power amps last, and turn them off first.
• It's always a good idea to use voltage spike/transient protection devices on the electricity outlet when using any sensitive electronic equipment.

Natural wear

Like other things the G-Force's components will eventually wear out. You can always check components by running the Selftest program, which is accessed by holding down the Bypass button during power up (see the manual).

The Value wheel is probably the most critical mechanical part on the G-Force. For example, when dialing through the Pitch Shift parameters you can easily produce thousands of clicks in just one tweaking session. If effect parameters respond in strange ways to the wheel's movements, it might have started to wear out. An example of this is if the parameter values decrease slightly when you try to increase them by rotating the wheel fast. Actually the Parameter and Value wheels are rotary switches, not potentiometers, so I'm not sure if contact spray would help like on an oxidized potentiometer. To save the Value wheel you can try to import a similar effect from another preset, instead of re-dialing it. See the manual on how to copy effect blocks between presets, section "How to recall a single block from an existing preset". There's a list of factory presets which covers some Pitch Shift and Delay parameter settings.
