180 Patches/ 90 Presets

The DG60FX-112 comes loaded with a total of 90 preset tone settings created by tone designers from the United States, Britain and Germany. This expansive collection of sounds covers a wide range of genres to provide guitarists with plenty to choose from right out of the box.

s Real Time Controls

No more calculating delay times, just tap the foot switch in tempo and the time is synced. What could be simpler? An optional FC-7 expression pedal achieves vintage style Wah Wah or can be used to control volume and 14 other effect parameters (up to 8 simultaneously) in real-time.

s Speaker Simulator

Add the "live" characteristics of speaker to the line signal with the Speaker Simulator. Choose from 16 simulator types that cover a variety of speaker sizes and configurations.

s Digital Output
Perfect for the studio, the DG60FX-112's 48k Digital Output delivers a noise free digital signal to a computer, digital mixer, digital recorder, or any other device capable of handling digital audio.
The foot switches can be used to access any of the 180 patches, built-in tuner or tap functions, or turn the s Built-in Tuner effect blocks on/off. The unit is also A built-in chromatic tuner utilizes five of the effect button lamps and three LEDs on the foot switch to help you accurately tune your guitar to any pitch. equipped with LEDs for easy identification.

VR Check Using the UP and DOWN switches, select 2 and then press the STORE switch. Press switches in the order of AMP SELECT, GAIN until PRESENCE, then from COMP to REVERB and finally until EXP.PEDAL is reached. Turn the control fully in the direction toward the left 7 segment LED which is turned on. If the test result is OK, the right 7 segment LED lights up. Then turn the control to that direction. If the test result is OK, proceed to the next VR. After completing this check, return the control to the center position. If an error exists outside of the control being checked, E meaning an error appears at the left end OF LED. In such case, press the UTILITY switch for resetting. At the end of all VR checks, all LED segments light up and go out. Then checking advances to the next step. Battery Check Using the UP and DOWN switches, select 3 and then press the STORE switch. If the check result is OK, all LED segments light up and go out. Then checking advances to the next step. In case of an error, E is indicated by LED. MIDI Check Using the UP and DOWN switches, select 4 and then press the STORE switch. If the check result is OK, all LED segments light up and go out. Then checking advances to the next step. In case of an error, E is indicated by LED. The numeric figure at the right end of LEF represents, 0: transmission and 1: reception. SRAM Check Using the UP and DOWN switches, select 5 and then press the STORE switch. If the check result is OK, all LED segments light up and go out. Then checking advances to the next step. The numeric figure at the right end of LEF represents, 0: IC2 and 1: IC3.
DSP Electric Characteristic Using the UP and DOWN switches, select 6 and then press the STORE switch. The same output level is obtained when No. at the right end is 0 and when it is 1.
