About Your New Blues Cube Stage / Artist / Tour
Guitar Amp as a Musical Instrument
An electric guitar doesn't come alive until it's plugged in. Your amp can actually be considered part of the instrument.
In fact, it's almost like the body of a great acoustic, contributing greatly to the final sound.
Even a vintage guitar can't give you all it's got if you use a mediocre amp.
Dramatically Evolved Tube Logic
The quest to find the Blues Cube tone started with the component of the same very basic tube circuitry as Fender Bassman's. Specifically, that is 12AY7 and 2 stage of 12AX7 for pre tubes, passive tone stack, longtailed pair phase inverter, 6L6GC power tubes with pushpull method, output trans. Its power section contains GZ34 rectifier tube, and the fixed bias method is adopted for power tube.
Types of power supply such as B+ power supply or C- power supply are significant factors that are deeply related to the curve of power tube gain or saturation, and not only types of tube but the way of power supply is the important factor to determine the characteristics of amp sound.
There is a certain point in the dynamic change in power supply to power tube that produce a very good feeling for musicians. That is to say, attack and sustain go together, or in other words, the characteristic bite feeling and compression feeling of tube go together. We have made the balance of adjustments to the feelings over and over again. Warm, bouncy, responsive, dynamic, elastic...these are all terms that guitarists use to describe the satisfying experience of playing their favorite tube amps. Thanks to Roland's Tube Logic, these words can be applied to the Blues Cube as well.
Dramatically evolved from the first-generation sound of the original Blues Cube amps from the '90s, today's Tube Logic accurately provides the complex, highly interactive behavior of classic tube designs in meticulous detail, providing the magical "it" factor that takes a guitar amp from a simple sound system to a living, breathing musical instrument. Great feel, distortion control with touch and volume, bloom, sparkle, power supply "sag," and more—everything that players love about a finely tuned vintage tube amp is present in abundance with the Blues Cube.
Performance-Ready Amp for Pro Players
Ready for live playing, the Blues Cube Artist is equipped with 80-watts of power (Blues Cube Stage is equipped with 60-watts), plus a custom 12-inch speaker that's been specially designed for maximum tonal response with Tube Logic. The open-back cabinet features poplar plywood construction, which offers acoustically vibrant tone for solo or group performances.
Wide-Open Sound at Any Volume (Power Control)
Every tube-amp player knows that you really need to turn up the volume and push the output tubes to get the amp to sing at its best. The downside is that the sound simply becomes too loud for playing anywhere but the biggest stages—though that's certainly never stopped guitarists from trying! The power amp section of the Blues Cube uses a high-impedance drive circuit to drive the speaker in an authentic way. Even within the power amp section, the bias circuit for each component such as NFB, phase inverter, output transformer network, and power supply uses an independent circuit structure and is tuned independently.
With Tube Logic, the Blues Cube authentically delivers the complex distortion characteristics of output tubes and their interaction with the output transformer, with the sound getting richer and the feel becoming more dynamically responsive as the overall volume is increased. But with the Blues Cube's variable Power Control, you're able to enjoy this musical, cranked-up tone while matching the volume to any situation, from recording to rehearsals to nightclub gigs and beyond.
Clean, Crunch, and Dual Tone
The Blues Cube has two independent channels—one voiced for cleaner tones, and the other for crunch. Each channel has its own Boost and Tone switches to shape the character. The Clean channel's single volume control dials in natural tube fullness and bite as the volume is cranked, while the Crunch channel's variable gain control provides a range of grit flavors from mild to aggressive. With the press of a switch, the unique Dual Tone mode lets you blend both channels together for an endless array of rich tones. And just like a vintage tube amp, the Blues Cube loves stompboxes, allowing you to further shape your personal sound by hitting the amp's front end with your favorite gain pedals.

IMPORTANT NOTES
Power Supply
- Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter or a motor (such as a refrigerator, washing machine, microwave oven, or air conditioner). 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.
Placement
- Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference.
- This unit may interfere with radio and television reception. Do not use this unit in the vicinity of such receivers.
- Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.
- Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. Also, do not allow lighting devices that normally are used while their light source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for extended periods of time. Excessive heat can deform or discolor the unit.
- When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated.
- Do not allow rubber, vinyl, or similar materials to remain on this unit for long periods of time. Such objects can deform or discolor the unit.
- Do not paste stickers, decals, or the like to this instrument. Peeling such matter off the instrument may damage the exterior finish.
- Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface. You can place a piece of felt or cloth under the rubber feet to prevent this from happening. If you do so, please make sure that the unit will not slip or move accidentally.
- Do not place containers or anything else containing liquid on top of this unit. Also, whenever any liquid has been spilled on the surface of this unit, be sure to promptly wipe it away using a soft, dry cloth.
Maintenance
- To clean the unit, use a dry, soft cloth; or one that is slightly dampened. Try to wipe the entire surface using an equal amount of strength. Rubbing too hard in the same area can damage the finish.
- Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.
Additional Precautions
- 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.
- When 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.
- A small amount of heat will radiate from the unit during normal operation.
- To avoid disturbing others nearby, try to keep the unit's volume at reasonable levels.
- When you need to transport the unit, pack it in shockabsorbent material. Transporting the unit without doing so can cause it to become scratched or damaged, and could lead to malfunction.
