About Your New Blues Cube Hot
Introduction
Congratulations!
You’ve made the right choice.
The Blues Cube is the happy result of using Roland’s technological expertise to obtain the
best possible sound from your electric guitar.
But to get the most out of your Blues Cube, you should go through this manual.
You don’t need to keep most amp manuals. But this one will explain important stuff
about what makes a great sounding amp and how to get that killer tone.
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 push-
pull 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 Hot is equipped with 30-watts of power, 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.
