Basswitch IQ DI Basspreamp / Direct Box


The Basswitch IQ DI bass preamp opens up new dimensions in bass signal amplification and routing and offers an “all-in-one” solution whether used in stand-alone mode or as the control centre of a pedal-board.

The basswitch IQ DI features an A/B-input switcher, a high quality bass preamp, a clean booster, a parametric EQ, an FX Loop switcher and last but not least a professional quality D.I. box.  The switchable input impedance guarantees an optimal treatment of the signal whether it comes from a magnetic or a piezo pick-up.

German manufacturing and best brand components warrant maximum reliability and optimal treatment of the electrical signal from your instrument.

Uncompromising in sound, flexibility and manufacturing the Basswitch IQ DI bass preamp gives the professional user the certainty to be adequately and optimally prepared for any situation, be it in a live performance or in a recording situation.

The Basswitch IQ DI bass preamp is the Swiss Army knife that should be part of the equipment of every demanding bass player.

 A/B input switcher.

If two instruments are connected to Input A and B, the A/B footswitch permits toggling between the two inputs of the bass preamp, whereby the signal from input “Instrument A” is routed to Channel A of the pedal and the signal from input “Instrument B” is routed to Channel B. If only one instrument is connected to “Instrument A” the A/B footswitch routes this signal to Channel A or Channel. This allows to call off per footswitch either an adequate sound setting for the second instrument or to make available a second sound setting for one instrument for instance for slapping or when changing from finger style to plectrum playing.

 High-end bass preamp with parametric EQ.

The Basswitch IQ DI features a high-end bass preamp and a four band EQ with double semi- parametric mids specifically designed for bass instruments.

• FX Looper

The Basswitch IQ DI offers two effect loops, a passive serial loop and a switchable infinitely variable mixing loop, that enables you to go from a completely dry signal, via parallel to serial looping. A phase-inverter ensures that any out of phase signals do not cancel each other out in parallel mode. Additionally a Tuner Out keeps the tuner out of the signal path.

• Clean booster

A footswitch and a volume control allow you to add a second high-end amplification stage upstream of the Mix Loop. This allows to provide tracking - or overdrive/distortion pedals with an adequate input signal. If the Mix Loop is not in use, the booster serves as a real clean solo booster.

• D.I. box

The Basswitch IQ DI bass preamp can be used to send the output signal directly to a mixing console. The high-quality components and features of the Basswitch IQ DI (high-end preamp, Lehle transformer, ground-switch, pre/post signal-processing switch, pad for output attenuation, rugged construction) make the Basswitch IQ DI bass preamp an excellent D.I. box, be it in a live setting or in the studio.

• Line-Mixer

Although the Basswitch IQ DI bass preamp was not originally designed for this application, it can also be used as a line mixer. To do this, the return socket of the Mix Loop is used as input and the ratio of this signal to the signals coming from inputs A and B is adjusted by using the mix control.
