IMPORTANT NOTES 291b In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY" on pages 2, 3, 4 and 5, please read and observe the following: Power Supply 301 Additional Precautions 553 · Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter (such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet. 307 · Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions. 556 · When connecting / disconnecting all cables, grasp the connector itself--never pull on the cable. This way you will avoid causing shorts, or damage to the cable's internal elements. 557 · Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices. 308 · A small amount of heat will radiate from the unit during normal operation. 558a · Although the LEDs are switched off when the POWER switch is switched off, this does not mean that the unit has been completely disconnected from the source of power. If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. For this reason, the outlet into which you choose to connect the power cord's plug should be one that is within easy reach and readily accessible. · To avoid disturbing your neighbors, try to keep the unit's volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you (especially when it is late at night). 559a · When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials. 562 Maintenance 401a · Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions. · Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable. · Wrap the power cord around the cord hook when transporting or storing the unit. · For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. 402 · Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. 5 Panel descriptions Control Panel fig. 01-01 8 9 10 11 12 15 16 17 1 4 2 3 5 6 7 13 14 1. INPUT Jack Connect your guitar here. DISTORTION Harder distortion than OVERDRIVE. 2. SELECT Switch Switches between the CLEAN and LEAD channels. [. . . ] If this happens, use connection cables that do not contain resistors, such as those from the Roland PCS series. 9 Sample Settings Alternative Metal The perfect sound for heavy, sharp riffs. Select the high-gain METAL STACK, then use the equalizer to boost the low end even more. Used with a humbucking pickup in the rear position, it results in an extreme distortion effect. Plus, you can add a long delay to use this as a lead sound with great sustain. [. . . ]
