[. . . ] When you rotate each value knob, the AX1500G will enter edit mode (the effect program switch LED and the edit icon will blink). The name display will show the parameter name, the MASTER/VALUE display will show the parameter value, and the sound will change. If you wish to change an effect that is in use, use the effect select knobs to select the desired effect. It is not possible to edit when other functions are assigned to the value knobs, when the AX1500G is bypassed, muted, or recording in Phrase Trainer mode. Editing example As an example, we will explain how to select TUBE OD as the drive amp effect for channel B. Press the effect channel switch to select channel B (the channel LED will light red). If the name display indicated "TUBE OD" when you pressed the effect block select switch(DRIVEAMP), simply continue. If the effect select knob was already located at TUBE OD, first select a different effect model, and then turn the knob back to TUBE OD. The effect block LED will begin blinking, indicating that it has been selected for editing. (The name display will indicate the model name as "TUBE OD. ") If you selected a programmed effect, the "ORIG" icon will light. The five value LED's will light, and the corresponding value knobs will be assigned to DRIVE, LEVEL, TREBLE, MIDDLE, and BASS respectively, and will function as knobs that adjust the value of each parameter. (Refer to p. 16, "Effect parameters. ") 12 Setting the noise reduction and program levels 1. By rotating value knobs 1 or 2, or pressing the NRPRG LEVEL switch, you can access the screen displays for adjusting the noise reduction and setting the level for each program. To adjust the amount of noise reduction, use value knob 1 (range OFF. . . 10: shown in the MASTER/ VALUE display). To adjust the level of each program, use value knob 2 (range 0. . . 10: shown in the MASTER/VALUE display). You can also use the MASTER/VALUE switches to change the character. If you wish to save the modified program name, you must perform the "Program write" operation. If you turn off the power or select a different program without writing the program, the program name you edited will revert to its previous setting. Writing programs Here's how to write an edited program. Press the WRITE switch, and the name display will indicate "WRITE. " The bank number display and the program LED will blink. Use the MASTER/VALUE switches (v, w) to select the writing destination bank, and use the cursor switches ( , ) to select the writing destination program. Press the WRITE switch once again, and the display will read "COMPLT" to indicate that the program has been written. You will then return to Play mode. You can also use value knob 5 or the bank switches to select the bank, and the program switches to select the program. Noise reduction Level Instead of value knobs 1 and 2, you can also use the cursor switches ( , ) to select a parameter and use the MASTER/VALUE switches to adjust the value of the parameter. Depending on the guitar that you use, raising the noise reduction setting too high may cause the sound to be cut off at low levels. The volume of each program will change depending on the guitar that you use. If you wish to save the noise reduction and program level settings that you edited, you must perform the "Program write" operation.

Pitch discrepancies produced by unevenness in the rotational speed, and the distortion and loss of audio quality due to the magnetic tape are also simulated. [. . . ]
