  • Page 4 We called it the "Mo' Bass." The name stuck. But then another vision came to mind. What if we could combine the best of the Mo' Bass with the best of SWR? What if we made the ultimate bass head - the famous SWR preamp with the patented Aural Enhancer circuitry, the Mo' Bass effects, and a stereo power amp capable of delivering 400 watts per side? Marrying the circuitry of SWR's founder and designer - the legendary Steve W.

  • Page 7: Getting Started

    The Mo' Bass speaker outputs can be run in either stereo or bridged/mono modes by using the stereo/mono selector switch on the back panel. For most situations the obvious is true: if you plan on using two speaker cabinets, run the Mo' Bass in stereo.

  • Page 8: Front Panel Features

    Some people like to use certain effects - especially foot pedals - in front of their amplifier. In the case of the Mo' Bass, it's important that any pedal have an output close to unity gain in relation to its input. In other words, any pedal that might add a lot of gain to the signal may be better off in the effects loop than in front of the amplifier.

  • Page 9: Preamp Controls

    In other words, try not to go too crazy with the onboard EQ of your bass preamp right off the bat. If you are using a KEYBOARD with the Mo' Bass, we have found the best choice to be the Active input.
  • Page 10 Preamp Tube Though not a "control" function of the preamp, you should be aware that the preamp in your SWR Mo' Bass is a tube pre- amp. The tube is a specially selected 12AX7 and should not require replacement for one to three years, depending on usage.
  • Page 11 SubWave The Mo' Bass SubWave is a lightning-quick sub-octave wave engine. In plain terms, it hears the note you play and immediately generates a signal one octave below it. You may have heard the term "octave pedal" before. You may have even used one.
  • Page 12 Using The Bassynth The Mo' Bass Bassynth will react differently to every single user. Factors such as the kind of bass, the EQ of the bass, the pickup selection on the bass, the technique of the player, the Pre-Amp volume of the Mo' Bass, the control settings of the Basssynth itself, and the Bassynth Mix control will all come into play.
  • Page 13 With an active bass, the overall gain structure will be slightly different. You may find you want to back off on the Pre-Amp Volume of the Mo' Bass preamp to keep the Bassynth from seeing too hot a signal. Also, the tone controls on your active bass will greatly affect the Bassynth.
  • Page 14 "expression" foot pedal, like the type of pedals commonly used with keyboards. Simply plug the pedal’s STEREO cable into the "Filter Sweep Pedal" jack on the rear of the Mo' Bass. Set the Filter control to the minimum ('0'). Then strike a note and slowly move the pedal back and forth.

  • Page 15: Dual Mode

    Mix controls (SubWave Mix and Bassynth Mix) in the signal path of the unit. After the Chorus section (the last Mo' Bass effect in the chain), the signal then is routed to the power amps. At that point, the power amps can be run in stereo mode or bridged into a mono-block configuration.
  • Page 16 The second example is more esoteric but still important. If you've got all of the Mo' Bass effects on at once and you've come up with some crazy, freakish sound that might be unusable on its own, hit the Dual Mode switch and blend that freaky combi- nation of sounds back in with the clean signal.
  • Page 17 External Effects Blend Controls Believe it or not, there are some effects not available in the Mo' Bass, like reverb and delay. For those who want to take tweaking to the ultimate level, we've included a Stereo External Effects Loop, complete with Left and Right External Effects ("EFX") Blend Controls.
  • Page 18 Stereo Headphones Jack By inserting a set of stereo headphones into this jack, you can satisfy your urge to play through the Mo' Bass at all hours of the night without disturbing your neighbors - or even hooking up speaker cabinets. The headphone volume level is adjusted by the Stereo Master Volume Controls.

    XLR connection at a mixing console), use the "Lift" position. Moving the switch to the "Lift" position will interrupt or defeat the ground on pin 1. Pin out for the XLR jacks on the Mo' Bass are as follows:...
  • Page 20 Totally unaffected. It sees everything, just as before. So, if you want to run in "Dual Mode" and get the "clean" preamp sound on one output and the "wet" Mo' Bass effects on the other, simply set the "Line/Direct" switch to "Line", and use the "Direct Out"...
  • Page 21 - there's no substitute for experimentation and learning by trying all of the possibilities yourself. Before you get to the gig, call your friend with the mini-studio in his or her bedroom, bring the Mo' Bass over, and find out for yourself what the Mo' Bass Interface section is capable of.
  • Page 22 Remember: The Mo' Bass External Effects Loop is a TRUE STEREO loop. There is no "mono power amp input" jack that routes your mono signal source to both sides of the amplifier. If you wish to run the Mo' Bass in this fashion, you will need to split your mono signal source with a 'Y' cord and route the two ends into the Left and Right Effects Return Jacks.
  • Page 23 Mo' Bass Power Amplifier Minimum Impedance Ratings Here's what this means to the power amp in the Mo' Bass. As mentioned previously there are two power amps in the Mo' Bass, which can be run in stereo mode or bridged into a mono-block configuration. Let's discuss running in Stereo Mode first.
  • Page 24 Damage to the power amplifier section of the Mo' Bass may occur if speaker enclosures with total impedances less than the minimum loads listed above are connected to the speaker output section. The owner's manual that came with your speaker cabinet should state its total impedance.
  • Page 25 Left and Right (Stereo) Speaker Output Jacks There are two 1/4" jacks and one Speakon jack provided for each side of the output section of the Mo' Bass. The Left and Right speaker jacks are provided for use in the Stereo Mode only. DO NOT use these jacks when the Mo' Bass Power Amp Assign Switch is in the "Mono"...

  • Page 26: Internal Features

    Make sure all vents are unobstructed when installing your Mo' Bass in a rack case. This will allow for cool air to come in and hot air to escape. Viewing the Mo' Bass from the front, the right side is the air entry side, while the left side is the air escape side.
  • Page 27 In this manner, we feel we have produced a more reliable amplifier, but, at the same time, the outside of the Mo' Bass will get warmer than cases made out of steel.
  • Page 28 How can I send the exact same thing to a mixing board? A: For the wet signal, send a line from the XLR Mo' Bass Out. For the clean signal, send a line from the either Direct Out, and put the Line/Direct switch in the Line position.

  • Page 29: Signal Path Diagram

    Q: Will the "Mo' Control" footswitch be able to memorize settings on the Mo' Bass? A: It will memorize groups of effects, but not actual settings because the Mo' Bass is not a digital device - it's analog. When a preset group of effects engages, the settings for each control will be wherever the knobs are set at the time.
