T-Rex is definitely not one of those brands that you see on every corner of the market. Unlike other brands, it does not pop up as frequently, but that makes it even more desirable in my opinion. If you have never heard about this manufacturer before, I will tell you that it is a small company in Denmark that has been around since 1996. The abundance of the years they have spent in the world of effects pedals means that they have enough experience to create the most wonderful pieces. Their technology is comprised of the parts that are carefully picked specifically for their devices. They consider the quality of every single component – be it a footswitch, board or the pots under the knobs. T-Rex has proven many times that they can be trusted which is one of the reasons why they are so awesome. Oh, and they are renowned with their signature pedals as well. I guess that is enough information about the brand and it is high time I introduced our prominent pedal to you: today we are going to talk about their Octavius Tri-Tone Generator. As you have probably guessed from the name, this thing can create defined octave effect, give you quite a few possibilities in that territory and then some. If you want to know more, read this article till the end! Let’s begin!

Features

T-Rex Octavius has a lot to brag about, my friend, but it leaves the words to you and lets the performance speak for itself. Its features consist of everything you would need to produce something characteristic and transform your instrument completely (that is a secret superpower of the octave effect). First and foremost, it blends together three different tones: it takes your original signal and splits it in three. The first one goes up an octave, the second one goes down an octave, while the third remains untouched. Not only does it create multi-layered effect, but it also acts as a clean boost whenever needed. You have the ability to amplify wet signal or ignore the octave and simply intensify whatever you are playing. Octavius has two footswitches with their own assignments. This way you can access the boost option on the fly and employ it whenever needed without having to lean down. I cannot help mentioning the design of this pedal, which is a bit too soft for the superpowers of this one. As you look at the purple (or something like that) enclosure, you do not think that you are dealing with a capable beast. But it is just a cover – and you will be quickly convinced in that once you plug in. In order to power up this baby, you will need a 12V DC adapter with a current draw of 1250 mA. Luckily, external power supply is included in the package so you do not have to worry about finding the perfect one. And one last thing, T-Rex Octavius is built in compliance of the EU rules about environmental protection – just in case you care about that topic. It goes without saying that this baby has outstanding properties, don’t you agree?

Controls

Since the whole design is well-thought-out, the brand considered every detail of the effect and decided to create the control panel that would suit the character of octave perfectly. The knobs we have here are laid out in an intelligent manner and interact with your sound beautifully. They are easy to understand and make it possible to plug in and start jamming right away. Such an intuitive approach is one of the many virtues of Octavius.

Let’s discuss all the knobs in the order of the control section itself. The first one here is Lo Oct that determines the volume of the sound that is an octave lower than the original. Next to it you will see High Oct that basically does the same thing but for an octave up signal. Below these two you will notice Master Mix, which sets the volume of both octave effects compared to the unaffected signal. This way your guitar sound will still be heard if you choose subtler settings. The last knob we have here is Boost, which determines the overall volume of the affected sounds (but it can amplify your dry signal as well). Moving on to the footswitches, the first one activates/disables the pedal, while the second one triggers the boost function.

Sound

The sound of T-Rex Octavius cannot be described without mentioning its tracking capabilities. Though that feature is significant in other effects as well, it is particularly important when we are talking about the octave. Luckily, this pedal has ethereal tracking that is smooth and seamless no matter what you play – single notes or chords. Yes, this does mean that it is polyphonic, a huge thumbs up to that! More importantly, Octavius gives you the ability to utilize both octave up and down effects simultaneously and create multi-layered tones. This way you can mix together the beefiness of lower octave to the high-pitch character of the high octave. When employed separately, they both have beautiful sonic outcome: octave down makes your sound fuller and suits perfectly any distortion you pair it with, while octave up turns your 6-string into a 12-string in no time. Clean boost is perfect for adding extra something to your sound and accentuating its best qualities. As you blend everything together, you will notice that each parameter is an ingredient that improves taste and takes it to a whole new dimension. That’s how amazing this baby is!

Conclusion

All in all, T-Rex Octavius is a beautiful looking, perfect sounding pedal that knows octave effect to its core and treats it accordingly. It does also know how to interact with your guitar and make it sound better. The easiest way to describe this pedal would be to say that it amplifies the best qualities in everything it touches, while making your sound fuller and more dimensional. If you are into the cleaner octaves, this one is definitely worth trying out. Good luck!
