[. . . ] 14, 15) TAP Indicator This is lit when the MEMORY/TAP pedal is used for Tap Input. 19 Part Names and Functions Rear Panel fig. 26 INPUT Jacks (A (MONO), B) This is the input jack for connecting to the output of an electric guitar or other instrument or effects processor. 4) PHONES Jack You can connect headphones here to monitor the sound. * Turn on the power before you connect headphones. When turning off the power, first unplug the headphones, then switch off the power. * Please observe due caution when using headphones while the Output Mode is set to +4 dB, since their volume may get significantly higher. * The INPUT A (MONO) jack also doubles as the power switch when the unit is running on battery power. The power comes on when a plug is inserted into the INPUT A (MONO) jack, and goes off when it is unplugged. Unplug any connected cords when the unit is not in use. AC Adaptor Jack This jack is for connecting an AC adaptor (BOSS PSA-series, sold separately). Using an AC adaptor makes possible long performances with no worry about batteries going dead. CTL PEDAL Jack Connect an external control pedal (the optional BOSS FS-5L/FS-5U) to this jack. You can use the external control pedal to turn the effect on and off, to input the delay time with Tap Input, and to switch memories. 31) OUTPUT Jacks (A (MONO), B) This jack is for connection to a guitar/bass amp, another effects processor, mixer, MTR, or the like.

Sounds are overdubbed during loop playback only while the pedal is held down. Continue to hold the pedal down as you play the phrase you want to record. * If the ON/OFF pedal is held down only for a brief period, loop playback stops, and the recorded phrase is erased. By pressing the MEMORY/TAP pedal during loop playback, you can have the delay applied to the guitar sound as loop playback continues. To stop loop playback, press the MEMORY/TAP button again (we recommend Pedal Mode 2 or 3). 21 How to Use Each Mode How to Use TWIST 1. The delay sound starts to oscillate, then the oscillation speeds up as its pitch increases. fig. 32 Blink 3. The oscillating sound begins to fade away, and the normal delay sound returns.

LEVEL knob). * You can switch the normal effect on and off by pressing the ON/OFF pedal only briefly. How to Use WARP 1. The effect corresponding to the knob positions (E. LEVEL, F. BACK) resumes. You can create fantastic effects by repeating the "warped" delay sound and then playing a phrase on top of this. [. . . ] Manual delay time settings change unless the Write procedure is carried out. The settings are saved when you press the DELAY TIME knob or switch memories. The delay time does not reach the maximum of 23 seconds The range of the delay time setting may vary according to the mode and the tempo setting. 26). 36 Sample Settings SMOOTH (Memory 1) fig. 36 Roland SPACE ECHO RE-201 (Memory 2) fig. 36 MODE: TAPE HEd2 DUAL (Memory 3) fig. 36 MODE: DUAL/SHORT 50 msec 37 Sample Settings MODULATE (Memory 4) fig. 36 MODE: MODULATE/RATE 80, DEPTH 70 TWIST fig. 36 Holding down the ON/OFF pedal produces the twist effect.
