Tierra Audio Flavour Preamp – Model Truffle

Studio-quality microphone booster for Vocals, Instruments or Podcasting


Intense Sound – Hard Saturation – Daring and Exclusive

Truffle, our most daring and exclusive sound. It brings an abundant amount of saturation to the sound. From the beginning, you will hear a very evident but contained and musical distortion. Many of you will enjoy this new alternative for your voices, but also for your drums and percussions.

It’s not a flavour for everyone or with which to dress up all your recordings, but a pinch on the right voice or instrument will delight your audience.


  • BOOSTED GAIN: +32 dB.
  • FREQUENCY FILTER: less treble.
  • HARMONIC DISTORTION: A lot of musical distortion provided by its exclusive germanium diodes.

Flavours Preamps is a collection of studio-quality microphone inline analog preamplifiers that will bring an extra dose of gain, texture and colour to your vocals and instrument recordings, and live performances.

Thanks to the wide range of flavours offered, you can enjoy different gain levels, from an enhanced and crystalline sound to different types and intensities of “sonic flavours” specially designed to bring a unique character, always without losing a drop of musicality. You will get warmer nuances and sounds, others sharper or hotter, others denser, others more saturated, others with more definition, more grain, or even more crunchy.

Simply plug in your favourite microphone and start singing or playing your instrument: You’ll be amazed at your “new sound”!

Like all our products, the Flavours Preamps are handmade with tons of love in Madrid (Spain), with circuits and electronic components of the highest quality. They result from the joint effort of engineers, musicians, designers, and producers to provide a full range of “portable flavours” that will enrich and nuance the sound of your microphones.

Your creativity will rule as you record voices and instruments of all kinds!

Your sound always with you.

Put them in the backpack, keep them in the guitar case, purse, or the car’s glove box.

They are ultra-compact and don’t need batteries or additional power cables, so you can use them comfortably not only at home or in the recording studio but also in the rehearsal room, in your live concerts, in your streaming and videoconference sessions, or working on your productions all over the city, or while traveling or on vacation.

What flavours are there?

Truffle, Cocoa, Mint, Chilli, Vanilla, Pepper and Salt.

We have designed seven different flavours, offering a very versatile sound range to help you improve the sound of your lead voices, choirs, Spanish guitars, acoustic guitars, electric guitar, bass amplifiers, and all kinds of string instruments such as violins, cellos or double basses, percussion instruments… In short, any voice or instrument that can be picked up by a microphone.

Each of the models offers a different gain level (all boosted), as well as a possible frequency filter (more or less bass, mid and/or treble) and a certain harmonic distortion (soft or hard), or even an improved but totally neutral sound, without additives.

Which microphones can I use?

Dynamic Mics – Passive Ribbon Mics – Condenser Mics (+Phantom Power)

Flavours Preamps are specially designed for safe use with dynamic and passive ribbon microphones, as they are the microphones that usually generate the smaller signal and need the biggest sound boost. For example:

Shure SM7B, Shure Beta 58A, Shure SM57, Shure SM58, ElectroVoice RE20, Beyerdynamic M69N, M130, M160, AEA R84, Coles 4038, Royer Labs Passive Ribbon Microphones, SE Electronics VR1 Voodoo, t.bone passive ribbon microphones, and others.

We guarantee that the phantom power will never reach the microphone.

If you want to use the Flavours Preamps with condenser microphones or with active (phantom-powered) ribbon microphones, you will have to use an external phantom power source to feed your microphone.

By the way, USB microphones cannot be connected to the Flavours Preamps, only microphones connected via balanced audio cables with XLR connectors (male-female).

The output of Flavours Preamps is a boosted balanced microphone signal (output is not a line signal).

How do they work?

The seven “sonic flavours” we propose are born by passing the signal from your microphone through different 100% analog electronic circuits that transform it in the entire frequency spectrum. Just like when you look for a specific flavour while cooking your favorite dish, depending on the sound you want to obtain, these circuits are formed by different ingredients (electronic components of the highest quality), with which we build filters and amplification stages that fulfill very specialized tasks.

Also, five of our Flavours Preamps incorporate a crucial ingredient: a premium input transformer.

The transformer amplifies the signal by passing it through a copper winding around a metal core that excites the signal and gives it an extra dose of harmonics: pure colour and tasty sound. Choosing a transformer is not an easy task. There are hundreds and hundreds of manufacturers, models, and features to try until you find the one which best fits the purpose, the flavour we are looking for.

Thanks to our extensive experience in the world of ProAudio, we know and work with the best international brands of transformers. Therefore, we have selected models of prestigious brands such as Carnhill® (UK) and Lundahl® (Sweeden).

Each of the selected transformers is specially designed to provide even or odd harmonics to your sound, more or less saturation, amplification, colour, and even noise, and all in an incredibly musical way!
