[review] T-Rex Quint Machine (by Bieke)

T-Rex from Vejle, Denmark started out in the mid nineties, making MIDI switchers and then moved to making guitar effect pedals. Their first pedal line up consisted of a compressor, tremolo, overdrive and distortion and these were embraced by the pedal aficionados and praised as being top quality pedals.

They were. And T-Rex did not stop there and went on to release great sounding modulation and time based effects. Apart from a side step into the world of boutique guitar amps, T-Rex continuously specialized in designing guitar pedals and accessories and unleashed the affordable Tonebug series, the Dual function pedals, a series of tube pedals, power supplies, pedalboards and bags, even multi effect and more recently a ... wait for it ... tape delay – ay - ay – ay.

So, T-Rex has not been sitting still and kept reinventing their own line of pedals, nowadays it consists of a line-up of sleek compact pedals. One effect that T-Rex did not offer was a pitch shifter.

Until now. Read on to find out more about the T-Rex Quint Machine.

T-Rex Quint MachineThe looks

A compact size pedal, it measures 60x50x117 mm, in a distinguished purple brownish color with a  darker striping pattern, in- and output and 9V DC socket on top.

Red status LED and soft FET bypass on/off switch, slightly off center. T-Rex badge in the middle.

The Quint Machine has 4 controls, Fifth Up, +1 and -1 Octave and Mix.

Stylish cream colored fluted knobs with black markers

The Quint Machine also takes 9V batteries, but drains these instantly, so better to user a power supply. And you need a special tool to gain access to the battery compartment, so not that practical.

The sounds

Yeah, it’s a digital polyphonic pitch shifter (well, according to the specs, it is an octave divider effect), so it definitely can do that cold and sterile digital sound, especially when used with a clean sound, the octave up effect can sound a little harsh. The octave down on the other hand sounds surprisingly pleasant.

Tracking is ultra fast and smooth with no audible latency whatsoever.

The octave down and octave up are highly tunable and can be fine-tuned to taste, and with the mix knob you can blend in your dry signal and get rid of the digital harshness.T-Rex Quint Machine

The fifth up control does what it says, it adds a fifth on top of the note you play, so if you play an A it will add an E on top of that. Nice for playing harmonies to a certain extent. Can be highly effective.

The Quint Machine sounds very tight when used clean, but it really opens up when you use a distorted signal, the Fifth control then becomes a mighty powerful tool for metal riffage and lead work. The Quint Machine works really well with other dirt pedals and can pull off quite convincing synth-like sounds, but you can also get it to do classic Octavia sounds.

It does not glitch it does not fart out wrong notes. It does not misbehave and can be a perfect add-on for creating harmonized ambient pads when combined with reverb o smooth layered sounds when used in conjunction with delay.

As a standalone effect, it pulls of a convincing 12 string sound, a superb faux bass sound, and a plethora of pitch shifting harmonies and with the mix knob you can blend in the pitch shifting perfectly, it’s quite easy to use, easy to get a good sound of.

It does not do organ sounds that well though.

The verdict

Well it is not cheap, but it is an easy to use pitch shifter, that can be subtle or in your face, but does not make a mess. Really great bass sim. Fast and accurate tracking. Killer tone.
