My friends, it’s been worth the effort!

Thank you very much,

Congratulations! With this amplifier from our ULTRABASS Series you have purchased a state-of-the-artBass Workstation that sets new standards. The ULTRABASS is an extremely powerful2-channelbass amp equipped with genuine BUGERA™ speakers. It gives you loads of power and makes sure that you always have a few extra watts available whenever you need them. The other items on the list of features are no less impressive: The ULTRABASS has one clean and one distortion channel plus one equalizer with aground-breaking“see-what-you-play”FBQ frequency display, which immediately shows you which bass frequency is assigned to whichcontrol—theperfect solution for sound tuning as you play. A musical limiter circuit protects the unit effectively against distortion, even at maximum volume. The connectors for headphones and CD players are ideal for practicing.

+This user’s manual will allow you to familiarize yourself with the control elements of your new ULTRABASS and learn all of its functions. After reading this manual, store it where you can easily find it for future reference.

1.1Before you get started

1.1.1 Shipment

The ULTRABASS was carefully packed at the assembly plant to ensure secure transport.

If the cardboard box is damaged, please inspect the ULTRABASS equipment immediately for physical damage.

+Damaged equipment should NEVER be sent directly to us. Immediately inform the dealer from whom you acquired it as well as the transportation company from which you took delivery. Otherwise, all claims for replacement/repair may be rendered invalid.

+If the unit needs to be shipped, please always use the original packaging to avoid damage.

+Never let unsupervised children play with the device or with its packaging.

+Please dispose of all packaging materials in an environmentally-friendlyfashion.

1.1.2 Initial operation

Please make sure that your ULTRABASS is provided with sufficient ventilation, and never place it on other amplifiers or in the vicinity of a heater to avoid the risk of overheating.

+Before plugging your ULTRABASS into a power socket, please make sure you have selected the correct voltage:

The fuse retainer near the power cord connector has three triangular markings. Two of these triangles point in opposite directions. Your ULTRABASS is set up for the voltage indicated near these markings, and can be altered by turning the fuse mount by 180 degrees. ATTENTION: This does not apply to export models built for 120 V, for example!

+If you use your ULTRABASS unit with a different voltage, you must change the fuses accordingly. The correct value of the fuses needed can be found in the section “SPECIFICATIONS”.

+Faulty fuses must be replaced with fuses of appropriate rating, without exception! The correct value of the fuses needed can be found in the section “SPECIFICATIONS”.

Power is delivered via the cable that was delivered with the ULTRABASS. All mandatory safety precautions have been adhered to.

+Please make sure that all of your equipment is grounded at all times. For your own protection, you should never tamper with the grounding of the cable or the unit itself. The unit shall always be connected to a mains socket outlet with a protective earthing connection.

The models BXL1800, BXL3000, BXL1800A and BXL3000A have a dual foot switch included. Connect the foot switch to the FOOT SW(ITCH) jack. Use the foot switch to select a channel (corresponds to theCH 2 button) and to activate the Ultrabass function (corresponds to theON button).

3.2.2 The Shape function

The Shape function on your ULTRABASS provides a revolutionary type of filter that you can use to modify your bass sound completely. The filter allows you to shape your sound – which is a must for bass players today. Extreme filter settings will give your bass sound more punch, for example:

You want to play a live bass solo but the sound doesn’t cut through. The solo should stand out, rather than being drowned. First, set up a solid basic sound on channel 1. Then, create a very distinctive solo sound on channel 2 using the Shape filter. Since the Shape filter is only effective on channel 2, you can change sounds quickly and easily before you begin your solo.

The Shape filter is worth its weight in gold when you are using two different bass guitars. Maybe you want to change from one instrument to another with a completely different sound. During gigs you often lack the time to set up your amp for a different instrument. Because you can use channel 1 for one instrument and channel 2, with its Shape filter, for another instrument, you’ll be glad to have the ULTRABASS.

3.2.3 The Ultrabass function

(not available on BXL450 and BXL450A)

In current music production, extremely low bass sounds that are one octave below the lowest available bass guitar frequency are quite popular. Often, you can only create this sound in studios, because most bass amplifiers have no sub-harmonicsfunction. This is not true with the ULTRABASS. The Ultrabass processor gives you the ultimate tool to shape this contemporary sound.

You’ll be amazed to hear how deep your bass can sound with the Ultrabass function. Extreme settings can be particularly interesting if you want to give your sound added sparkle in the treble range. By the way, if you already set the Shape filter to create punchy sounds, but feel that there’s not enough power in the bass range, the sub-harmonicsprocessor is there to help you. Even if the sound is still punchy, it will have much more depth.

On the models BXL1800, BXL3000, BXL1800A and BXL3000A, the Ultrabass function can easily be switched on and off via the foot switch supplied. This allows you to highlight certain passages exclusively.

3.2.4 The compressor

(only BXL1800/BXL3000 and BXL1800A/BXL3000A)

A compressor is used to limit the dynamic range of a signal. Signal peaks are lowered and soft signals are raised in volume, thus reducing the difference between the highest and the lowest signal levels. The result is a much more powerful sound.

Some playing techniques, such as slapping, lead to high-leveldifferences. In this case, a compressor can be used to make thelow-leveldead notes clearly audible, which gives the bass line even more groove. What is more, the sustain of long notes is extended.

sUse the ON switch to activate the compressor.

sTurn the COMPRESSOR control slowly to the right to raise the compression intensity.

sPress the ON switch to compare the compressed signal with the unprocessed one.

Compressors work best if provided with high input signals. If the signal level is low, the effect will be activated only with high settings. If so, enabling the compressor can lead to extreme level differences. If GAIN is high, the compressor comes in quite early. In this case, you don’t need to turn up the COMPRESSOR control that far to achieve an effect. Experiment with it to find the best setting for your needs!

+The compressor works independently of the builtin protective limiter, which is always active on all BXL models and protects the power stage from overloading and distortion.


4.1Setup for practicing with playbacks

Fig. 4.1: Standard setup (here: BXL900A)

This setup is intended for rehearsals or practicing at home. Connect the ULTRABASS as shown in fig. 4.1. To feed in playbacks, connect a CD player to the CD input. Of course, you can also connect an MD player or a computer.

If you want to practice with headphones, just plug your headphones in the PHONES jack. The built-inloudspeaker will be muted automatically. Turn the MASTER control fully left before you connect the headphones.

4.2 Expanded setup for gigs and studio recordings (onlyBXL1800,BXL3000,BXL1800A andBXL3000A)

Fig. 4.2: Expanded setup (here: BXL1800A)

The following wiring scheme is recommended for live gigs or studio work. It builds on the standard setup.

Connect the foot switch supplied with the unit to the FOOT SWITCH jack on the ULTRABASS. Use the foot switch to switch channels and to activate the Ultrabass function, which is particularly useful when playing live.

To use an external effects device, connect the input of the effects unit to the FX INSERT SEND on the ULTRABASS, and the output of the effects device to the FX INSERT RETURN. Instead of the floor effects shown here, you can also use a wah-wahpedal or an external 19" effects unit.




If you want the bass signal to go through a PA system during live gigs, you would normally need a DI box. (DI boxes process the signals for long cables and provide a higher output level at the mixing console). The ULTRABASS amps have a DI box already built in! Connect the balanced DI OUT directly to the mixing console input or to the multi-corecable leading to the console. Use a microphone cable(2-coreshielded cable with XLR connectors).

Alternatively, you can use the LINE OUT (¼" TS jack) for short
