Modulation effects can be tricky: you might fall in love with them one day, go to the extreme, and steep your sound with waves of crazy fluctuations. But the other you might feel like being smooth and soft, exploring subtler types of the effects. This group includes vibrato, flanger, phaser, chorus and, most importantly, tremolo. The latter can be utilized in so many different ways that you might never stop exploring.

No matter how simple your unit is, the effect itself is so versatile that it will deliver all-encompassing performance. That is probably why the majority of the devices are straight-forward. Tremolo is something that has to be in your rig, since it can be quite an amazing tool for fattening up your sound in the most beautiful manner. For this reason, you have to explore the price range that suits your wallet in order to find the best option for you.

And to make things easier for you, today I will introduce the product that combines affordability with tiny chassis – Mooer Trelicopter. It is a pedal that fits huge performance in its small body and creates tremolo that will change your pieces quite a bit. If you are interested in such a device, then keep on reading! Let’s begin.


As you probably know, Mooer has stepped up its game a great deal. It is a leading brand in the affordable category, with their pedals always delivering quality in every detail. Trelicopter, in particular, does also follow that pattern. It has a full metal chassis that protects the insides like a real soldier. The interior is comprised of high-quality materials, as well, meaning that this baby will never give up on you.

It is part of a micro series from Mooer, which indicates on the fact that its tiny body will fit in a fist or a pocket. More importantly, Trelicopter has optical circuitry that recognizes your signal beautifully and creates tremolo accordingly. In order to guarantee maximum tonal quality, this pedal has true bypass switching. It will not suck your tone or ruin any of the frequencies.

On the contrary, it will maintain your sound in its original shape and keep it intact at all times. Though the small enclosure is extremely convenient, it has one minor flaw: this thing cannot be powered with batteries. But luckily, you can always utilize the power supply and you will be ready to roll. Trelicopter has a minimalistic design that seems exquisite from far away. The choice of color palette does go in the safe territory – you cannot go wrong with black and white.

But such configuration works pretty well for this one. The whole feel of the unit is that it looks and performs like a higher-end unit and that is an amazing benefit for this one. It exceeds its price range with its quality and will force you to reconsider your attitude towards affordable range. Mooer has once again done a perfect job while designing Trelicopter.


Before we move on to the juicy stuff and concentrate on the functionality of the controls, I have to mention one thing. Even though Mooer was intelligent everything else about this pedal, they did not realize that black knobs would be hard to see on the black surface. For some reason they decided to make one encoder white and kept the rest black. This is definitely not a deal-breaker, but it might be hard for you to see what is going on in darker venues. I am sure you will find your way around it but still it is something to keep in mind. With that being said, the whole panel is still intuitive and beautifully arranged.

I will start with the invisible ones first. Depth alters the intensity of the effect and modifies the amount added to your sound. It gives you the option to completely submerge your sound in tremolo and see where it takes you. Or utilize just a tiny bit and go from there. Bias changes the response of the optical circuit.

It can make your sound tighter or loosen it up when needed. This control is not something you will encounter in every other pedal and is definitely a selling point for this one. The brightly shining diamond of Trelicopter is Speed. It modifies the rate of the effect and allows you to enter the territory where things become hard to distinguish between. Though we do not have Level control here, you will not miss it. The rest is precise and will help you create refined tremolo.

Mooer Trelicopter Sound

The sonic capabilities of Mooer Trelicopter will definitely surprise you, especially if you are one of those people who are skeptical of affordable effects pedals. Let me tell you that this baby has outstanding tonal palette. Its controls have wide range of options to choose from and allow you to make your performance versatile. You can add just a tiny amount of tremolo to enhance the texture and body of your sound, explore middle settings or go crazy and experiment with fully saturated, fast effect that has a lot of character.

The Bias knob is especially useful, as it tweaks your sound from within and changes the way your pedal responds to your playing. The combination of internal features and external controls gives you the chance to scrutinize tremolo to its core, find the properties that you like the most and intensify them whenever needed. The choice is yours and how you decide to use this pedal will impact your sonic outcome a great deal.


On the whole, Mooer Trelicopter is way more than just another affordable pedal. It has quality that you will hardly find in the units of this ilk and it has some features that are only present in higher end models. If you have a tight budget, this is a fantastic option to consider. It will make your job easier and, thus, improve the quality of your performance. Examine everything this one has to offer and let it take you to the realm of amazing tremolos. Good luck!
