Effects Introduction

The M350 comes with 15 legendary TC effects. They are all a result of the award winning TC effects heritage, and our research and development department have been working double shifts to come up with these 15 super-tuned TC effects.

Dynamic Delay

The Dynamic Delay preset gives you the possibility to alter the delay output level actively depending on the dynamics of the input level. What that means is that you can have a low level delay when you’re passing a source through the device and a higher level of delay when you cut off or silence the source. Use it for instance to emphasize pauses in between phrases in a solo.

Triplets delay

Triplets are basic musical structures that have a great effect on our rhythmical perception, especially when played against something straight. The Triplets delay preset gives you a serious and versatile tool to rework your source material. Use it on e.g. guitar solos, horn solos or even percussive instruments.

Studio Delay

With a clear and concise reproduction of the original source material, the Studio Delay gives you a serious tool for studio work. It utilizes a subtle yet significant high cut with a relatively high crossover frequency that enables you to achieve a transparent and precise sound.

Soft Delay

If you’re looking for a clear yet soft reproduction of your original sound, you should try the Soft Delay preset. We’ve integrated a subtle yet significant high cut with a relatively high crossover frequency, which will give you a soft and smooth delay. This type of delay is perfect for studio recordings, and in fact you’ll discover that your tracks will sound very “studio like” when you use it.

PingPong Delay

A PingPong delay pans the delay repeats from left to right, and back, while at the same time keeping the original position of the input. The PingPong Delay preset is naturally no exception and it gives you a very wide-spread special effect that is crowd pleaser. Use it live or in the studio when you want a dramatic and unique sound.

Slapback Delay

The Slapback Delay preset is a very short delay that only counts one, two, or maybe even three repeats. Often this type of effect is used as a “doubling effect” in order to make the original source content more dense or solid. But you can also use the Slapback Delay on funky guitar riffs for instance.

Smooth Phaser

This phaser uses twelve all-pass filters at the same time, which gives you a well-adapted and very smooth sound. Use this type of phaser when you want the typical phasing characteristics combined with a more elegant and subtle approach. In other words this is an effect that gives you the typical phaser qualities with a sophisticated and delicate twist.

Vintage Phaser

The Vintage Phaser uses four different all-pass filters that give you a direct and to-the-point sound. Depending on how the filtered signal is mixed with the dry signal, you’ll get a strong and typical “phasing sound” that is extremely versatile. Use it with equal success both on the stage and in the studio.

Lush Chorus

If you’re the type of person that enjoy effects that will take your music one step up, then the Lush Chorus preset will be one of your favourites. It gives you a broader and more complex sound that is a perfect match for the funky and jazzy music styles that often have lots of solos.

Soft Chorus

Sometimes what you need is a natural, stable and well-tempered sound. The Soft Chorus preset is a basic chorus that you can use with eloquence on laid back styles of music like ballads, chill out and moody jazz. It will give you a sound that is true to the original source material and you’ll be surprised how often it will add that extra something to your music.

Inst. Flanger

TC flangers have been known for their perfect relation between speed and depth, and the Inst. Flanger preset is certainly no exception. This flanger gives you a classic “flange sound” with a wide and broad spread-effect. Use the Inst. Flanger when you want a large chorus-like sound that has all the typical and beneficial characteristics of a genuine flanger.


Compression can be pretty tricky and more often than not, you have probably been subject to “over-compressing”. With the Comp preset you’re on the fast and steadfast track to professional and easy compression. Use it for most sources where you want the benefits from a professional compression that won’t disrupt your original source.

Hard Comp

The Hard Comp preset is tweaked to deliver a hard yet “nice” compression to your source. What that means is that although the preset will compress your source relatively hard, it won’t disrupt and over-compress your source. Use this type of compression on e.g. drums and percussive instruments and achieve a signature sound.


The De-Esser preset removes all unwanted s’s that some microphones or singers have so much trouble with. Use it predominately on vocal material to clean up the sound and make the source more homogenous.


The Tremolo preset uses a wave shape that is triangular and that gives you an easily recognizable tremolo sound. This type of effect is a true crowd pleaser and it will work on many sources, although it is probably most known from 007 style guitar solos. It is a soft and appeasing tremolo that is quite useful for slower and more melancholic types of music.


Reverb Introduction

Inside the M350 you’ll find 15 shining world-class TC reverbs. Each of the reverb types is a result of extensive fine-tuning and research done at the TC reverb laboratories. Although the M350 is a non-expensive no-nonsense dual engine processor, you’ll find that the reverbs are some of the best and most versatile reverbs on the market.

TC Classic Hall

This reverb emulates a large hall with a broad and warm reverb, and a relatively long decay time. It preserves the natural characteristics of the original source, which gives you an incomparable and authentic large sound. Very often vocal source material call for the TC Classic Hall preset, but you can use it for a wide variety of studio and live applications.

Hall Acoustic

The Hall Acoustic preset is a broad yet slightly diffuse reverb. It simulates a large environment but adds a distinctive acoustic flavor to the source material. You can use this reverb with great effect on drums and other percussive material, but it is also be used when you want to create an unbiased yet genuine ambience.

Vocal Reverb

This preset will match and refine vocal sources that need that extra something. The Vocal Reverb preset gives you a soft and mellow tone that is identical to the reflections you get from medium sized rooms with wooden surfaces. Use it to obtain a personal yet subtle and agile sound on your vocals.

Live Vocal

The Live Vocal reverb emulates a large room or venue that has many wooden surfaces. The reflections from wooden surfaces give you a soft and smooth reverb type that will suit vocal material perfectly. If you’re seeking a large reverb with spongy reflections to use live or in the studio, the Live Vocal preset is the answer.

Drum Ambience

Going back in time to the 80’s the Drum Ambience preset simulates a small ambient room with very short reflections. This gives you a perfect reverb for all types of drums and percussive instruments that you would like to give that classic sound of the past. It can be used with great effect on studio recordings or even when you play live.

Drum Room

The Drum Room reverb will flavor your drum- and percussive source material with great elegance. The preset simulates a medium sized room that gives you a relatively long yet natural sounding reverb. It preserves the full spectrum of the source while giving it an unmistakably quality of brilliance and presence.


Emulating a large location with hard and uneven surfaces, the Cathedral preset gives you a broad and unevenly diffused reverb. This reverb type will open and colour your source with the natural ambience which is so typical of cathedrals. If you’re playing live this preset will be a crowd pleaser, but it is equally suited for studio use where a distinctive effect is called for.

Living Room

A small and well-furnished room with an intimate ambience is what the Living Room reverb simulates. Living rooms will absorb many reflections due to the soft materials in it, and that gives you a reverb type with few reflections that are sparingly sustained. Use it to get an intimate and to the point atmosphere.

Gold Plate

The Gold Plate reverb is a trip back into the past. In the old days before digital signal processing was invented, people used large metallic plates to create reverbs. This preset emulates that unique sound which is diffuse, bright and filled with nostalgia. The Gold Plate reverb can be used with superior excellence on percussive instruments.

Silver Plate

Going back in time the Silver Plate emulates the large metallic plates which were used to create reverbs before digital signal processing was commonplace. This preset gives you a light and relatively diffuse reverb which will work splendidly on percussive instruments that need a twist of the past.

Spring Vintage

Back in the old days they would use large springs to generate a reverb, and in fact this was used a lot in the old vintage guitar amps. The spring Vintage preset simulates this type of reverb and it will give you a distinctive vintage sound that is true to the original.

Live Stage

If you’re playing live you might want a reverb that can cut through all the background noise which is so typical at live gigs. The Live Stage preset gives you a grainy and bright reverb that will work equally well on vocals and instruments that need to be distinct and to the point.


This reverb is tailor-made for dry source material. It clearly defines a room and focuses on the early reflections which will add ambience and warmth onto many types of sources, e.g. dry drum samples.

Damped Room

The Damped Room reverb can be used with great results on source material which needs to be very lightly reverberated. The preset simulates a small studio or vocal box that is completely padded with soft- and absorbing material. It gives you a very tight and to the point sound.


If you want a reverb that is tight and with a predomination of early reflections, the Nearfield reverb will be your preferred choice. It emulates the small amount of natural reverb that occurs in e.g. a studio control room. Use this reverb type to obtain a tight, bright and smack-in-the-face sound.
