Award MB10 Matchbox DI/EQ/Speaker SimulatorArticle from Recording Musician, March 1993 |
This extremely versatile problem solver can function as a low-noise DI box, guitar preamp and speaker simulator.
The makers of the popular Sessionmaster guitar preamp looked at the DI box concept and thought it could be much more useful: the result is the Matchbox, a DI with a difference. Paul White strikes up a beautiful relationship...
When the guitar EQ is switched in, the Treble control becomes active, the equaliser circuit itself apparently being based on the passive designs used in valve guitar amplifiers. Effectively, it is a three-band EQ where the low and mid settings are preset and just the treble is variable, but there's more to this circuit than just EQ, as it actually simulates the voicing of a typical guitar amplifier, adding brightness and low-end punch. The EQ may be used either with or without the speaker simulation to produce a wide range of clean guitar tones, ranging from mellow to glassy bright, and the fact that the unit has a high input impedance means that the original tone of the guitar is not compromised in any way.
For overdriven sounds such as effects pedals or preamps, switching the speaker simulator in provides a warm sound that remains bright without being fizzy. It should be stressed that the Matchbox doesn't actually create overdrive effects, but the speaker simulation means that ordinary distortion pedals can be recorded with no problem. In practice, the simulation is very close to the sound you'd expect from a miked amp, though a little fine tuning with your desk EQ can be used to customise it still further.
The output from the Matchbox is at line level on a stereo jack socket which can be used balanced or unbalanced; there is no XLR output or provision for phantom powering.
For my tests, the Matchbox was plugged directly into my mixing console line input, and aside from its obvious versatility, was impressed by how quiet the circuitry was, even with quite high amounts of treble boost added.
In practice, the unit functioned perfectly as a conventional DI box for use with bass guitars and so on, but it also proved to be gratifyingly flexible when used with 6-string electric guitar. Without using any other effects or processors, a very acceptable clean guitar sound is achievable, while the addition of a compressor yields a very classy result indeed. It also works well with acoustic guitar pickup systems, bass guitars and even keyboards, where the speaker simulator can be used to create more of a warm, analogue sound from digital instruments. A side-benefit is that the high frequency noise generated by some MIDI synths is reduced by the speaker simulation filtering.
Given that this is a very modestly priced unit with so many potential uses, I can see it becoming very popular in both home and professional recording studios. It costs little more than a regular DI box, yet can make a world of difference when recording electric guitar and also comes into its own as a universal problem solver for matching levels or adding EQ to sounds.
