THE SOUND OF BLUES, SOUL AND ROCK 'N' ROLL This compact amplifier pays utmost respect to the sound of mid-60s Showman(R) and Bassman(R) amplifiers and 2x15 cabinets. The BassRIG '64 Black Panel is an analog recreation that pays utmost homage to the sound of mid-'60s Showman® and Bassman® amplifiers and 2x15 cabinets. Throughout the history of bass amplification, these powerful amp heads were trusted by everyone from soul session players to rock 'n' roll stars. ORIGIN EFFECTS believes these early bass sounds are the best out there, and the BassRIG '64 Black Panel delivers the warmth and grit of an era-defining bass sound. It features an entire valve amplifier circuit in a pedal-sized package, with all the controls you need to create the perfect bass amp tone. The BLEND knob adds and mixes in the dry signal (clean signal) to maintain clarity and the low end of the sound. It is equipped with an XLR DI output, which allows you to output a line-level signal from the analog cabinet simulator, so you can connect it directly to a mixing console or other device to deliver powerful, authentic Showman® and Bassman® tone. The output stage also features ORIGIN EFFECTS' unique post-drive filter, Amp Out EQ, which can be adjusted to suit the amp you're using. This filter ensures compatibility with any amp or cabinet, meaning you don't have to struggle with sound shaping or compromise on clean tone.・GET CONNECTED INSTRUMENT - Enter your bass or other instrument. AMP - Connect to an amplifier or power amplifier. DI OUT - Connect to a mixer or interface. Connect a 9VDC - 9VDC 2.1mm (minimum 150mA) center negative power supply.・SET THE AMP OUT EQ HORN CUT - When using with tweeter-equipped cabinets, set the HORN CUT switch to 2K or 4K for a smooth overdrive tone while protecting the tweeter. LF - Controls booming with larger cabinets or thickens the sound with smaller cabinets. HF - Adds upper mid presence or controls top end when used with modern hi-fi amplifiers.・SHAPE YOUR VOICE The tone control affects the frequency response as well as the overdrive characteristics. TREBLE - Turn clockwise for a brighter tone and more aggressive overdrive, turn counterclockwise for a smoother sound. MIDDLE - Turn clockwise for a warmer tone and richer overdrive. Turn counterclockwise for more tone and clarity. BASS - Turn clockwise for a deeper low end, counterclockwise for a thinner, more percussive sound. Tip: For overdriven sounds, lower BASS settings can improve tightness and definition. BRIGHT/FAT - BRIGHT adds more high frequencies to the preamp at lower DRIVE settings. FAT switches the circuit from Showman® to Bassman® specifications, adding warmth and depth to your sound. As DRIVE is increased, FAT mode starts to sound out of control (in a good way!). BLK/TWD - The BLK setting is a black panel circuit. TWD is a tweed circuit for even more gain and mids.・DIAL IN YOUR OVERDRIVE GAIN It transitions from clean to drive tones in the same way you would turn up a classic amp without a master volume.・BLEND IN YOUR DRIVE BLEND Turn clockwise to add more dry (clean) bass guitar signal, which helps maintain clarity when using overdriven sounds. DI OUT - Balanced XLR output provides an 8x10 bass cabinet analog-simulated line-level output for PA or recording interface. DI CAB SIM switch - When this switch is set to the FX position, the cabinet simulator is active only when the BassRIG Super Vintage is on. In the FX + BYP position, the cabinet simulator is always active. DI GROUND switch - Select GND if using only the DI output, or LIFT to eliminate ground loop hum when using both outputs.
