The InterBlock 45 provides all the key requirements for coupling an electric guitar or other electronic instrument to a PA or recording console, and also contains a built-in amp with enough power for practice or small gigs. It combines a full-service guitar preamp, overdrive section, effects loop, cabinet simulator, headphone driver, and 45-watt power amp in a single pedal-size enclosure. As the name suggests, it provides a complete interface between your instrument, your pedals, your DAW, your PA system, or a stand-alone loudspeaker, with lots of flexibility to handle whatever you may come across in your efforts as a performing artist. In spite of its diminutive size, this little powerhouse packs a potent punch capable of driving a serious stageworthy rig. The high impedance INPUT accepts normal guitar cables. The GAIN control ranges from clean to overdrive. The three band EQ adjusts LOW, MID, and HIGH frequencies, with two selectable EQ VOICE modes. FULLQ starts from a flat response with EQ at 50%, and the VINTAGE mode emulates the “Fender Style” tone stack. A full featured FX LOOP includes a secret “audio input” feature allowing an auxiliary music source to be “injected” into the FX RETURN, which further expands the capabilities of the InterBlock 45. The MASTER control adjusts the overdrive threshold from 0 to 45 watts offering clean headroom and/or rich overdrive at will. From the MASTER CONTROL, dual signal paths lead to the BAL LINE OUT/HEAPHONE jack, and the SPEAKER OUTPUT jack, which drives any normal speaker, and is stable with no speaker connected.
