Q:	When using with an optional expression pedal FP02, what kind of functions will become possible?

A:	The real-time control function of the effect parameter will become possible, using expression pedal FP02. For example, effects such as Wah, Pitch Shift, or modulation rate can be operated by the pedal.

Q:	As output level of each programmed patch is uneven, I would like to keep them even.

A:	Please adjust "PATLVL" parameter for each patch to keep the output level even. You can set up total patch level.

Q:	Is it possible for to change bank with only foot switch operation?

A:	Yes. When you step on foot switch [1]/[2] at once, bank gets back to previous one. When you step on foot switch[3]/[4] at once, bank moves to next one. You can access to all patches with only foot switch operation.(Hands-Free)

Q:	Is there any difference on GFX-1 and GFX-1FR in red color?

A:	There is no difference on function/performance between both models.

Q:	Sound is unnaturally distorted.

A:	When high-power guitar with active pickup is used, unwanted distortion may occur depending on DRIVE module effect type, because of signal saturation. Please adjust the level of each effect module or gain parameter reasonably.

Q:	Using high-gain distortion effects, noise level becomes higher.

A:	All drive effects such as overdrive, distortion, fuzz are produced by amplifying input signal. (not only ZOOM products) Therefore, a very little noise in guitar signal which comes from guitar pickup or guitar cable will be amplified together. To minimize noise level, please adjust ZNR parameter properly.
