The jazz series


We designed the GIG50 series because we wanted to offer jazz players a tube and solid wood instrument. Because we strongly believe that they are the two key sound components that made Jazz great.
Keeping in mind the needs of contemporary jazz players, we make them available in two formats: GIG50 Combo, a light, powerful and smart combo amp for the musician who is always GIGging around but does not want to give up his sound and GIG50 Head + Cabinet for those who do not wish to give up an amplifier outside the choir to play just another ordinary amplifier.

Watch the video to discover the entire building process of our Jazz amplifiers, from the selection of the tonewood to the finest details.

Listen to GIG50

We suggest you to listen the samples with an high quality audio system, otherwise you’ll hear a distorted sound.

Every wood we use has its own tone, its own personality and it was chosen to achieve a specific sound. This way the role of the cabinet shifts from speaker to instrument, from passive to active element of the signal chain. Our aim is to give you a cabinet that enables your guitar to sound at its best.

The Jensen P12Q has a very warm, mid-focused bite with clear, bright highs. When presented with overdrive distortion the P12Q remains well-balanced.

Elegance is in the details and we dedicate a lot of time and care to every amplifer. Starting from choosing the most resonant boards for the Cabinet and the most beautiful for the head: cause it’s the wood who makes every amplifier unique.

All the amplifiers are enhanced by the leather handle and the leather piping tailor made to define the profile of head and cabinet at their best.

Because we love fine details

“Wood and tubes, a man made tone”

The warmth of the tube’s sound, the light weight and the modern design. A new interpretation of the technology that made history.
Technology, design and a high fidelity sound allows you to hear the voice of your instrument without changing his soul. From now on, you guitar and your amplification will speak the same language

GIG50 is a perfect solution for recording studios. For its high performance it has been chosen by Artesuono Recording Studio.

Amazing sound, extremely quiet, powerful, all-tube, light and easy to carry. The head is customizable with different tubes. No more anonymous amplifiers in MDF covered with black vinyl, which produce more noise than sound … Besides being beautiful, GIG50 has great sound! Guitarists will be thankful!”
