I am honored to be an endorser of MGbass. Mauricio Costa is an extraordinary, generous, talented, and kind-hearted person. He gave me the chance to be an endorser and has created one of the most beautiful, boutique, and best sounding basses I have ever had. This bass is well made and Mauricio's attention to detail is evident in the feel and sound. What I like most about this bass is the ability to shape the tone to fit any style of music while still sounding modern. I also like that Mauricio has made the neck easy to play around the 24th fret. No other bass I have played reaches high up the neck comfortably.

I look forward to spreading the word about this instrument and owning more! Thank you for giving this up and coming bassist from Buffalo, NY his first endorsement deal and for making a one-of-a-kind great bass that is everything I want in a bass!

I have collected the best fretless basses from all over the world and once I got my hands on the MG, I couldn't put it down. From its "EXTREME" design, to its excellent build quality, to its ultimate fretless tone and feel, this bass has become my favorite fretless and my signature sound. On top of that, Mauricio is one of the nicest guys in the bass builder world. I look forward to collaborating with him soon on new designs and wood selections to create a huge collection of MG BASSES.

After several years of using MGBass, I have become an MGBass endorser. As a performer of a wide variety of music, I needed an instrument that had a unique sonic identity, yet was versatile. Mauricio has done that beautifully. Not only did this bass ooze style, it had a great sonic presence, was effortless to play, and tuned perfectly.
The production quality of the MGbass is excellent, the instrument is well made, and Mauricio's attention to detail is evident. He builds each instrument with love and care. Mauricio offers a wealth of knowledge and advice during the making process. He knows the woods inside and out and knows which pickups are best suited for specific needs. The instruments Mauricio and MGBass make are world class. I didn't just buy an instrument, I got the voice I was looking for.

I feel that the sound is quite a gap between what it looks like and what it sounds like.
It is light, well-balanced, and insanely easy to play. All the models are very playable.
For example, the NewExtreman Fretless4 is a bass that looks strange, but can produce the fretless sound that people call the masters of fretless basses produce. It is pleasant to play.
The Infinity Ghost 6 has no control knobs on the top surface, no fretline, and there is no other instrument that looks like this.
It's like the instrument inspires me to come up with ideas. It's the kind of instrument that takes you to a new world.
