Famous lecturer and solist, Ji Hye plays on the new Adams Alpha 5.0 Marimba. An instrument designed by KesselsGranger DesignWorks.
“During the Frankfurt Musikmesse Adams proudly presented the new ‘Alpha Series’ instruments. Many enthusiastic marimba and vibraphone players tried the instruments and gave extremely positive feedback. A new tuning of the keyboards and a beautiful design in collaboration with KesselsGranger DesignWorks absolutely brings the marimba to the next level.”

My first impressions of the Alpha - WOW! It's absolutely gorgeous. Not only is it a beautiful looking instrument, it's a beautiful, AMAZING sounding instrument.

The partnership between KesselsGranger and the artisans at Adams has resulted in an instrument that is unlike any other instrument on the market today.

How do we design success?



The start of a design project is exceptionally important. We listen carefully to the wishes of our clients in order to realise their dreams.



We think along with the client in order to optimally employ their service or production facility for the most advanced and efficient result.



Current service or products are critically analysed. With each design project we do our very best to create a new benchmark.



Through our knowledge in styling and finishing, each project is carefully developed for the most optimal appearance.



To ensure the best quality we work closely with the client until the last phase of development and during the production phase.



Our fees are sharp. We work together with starting entrepreneurs and fully established organisations. We welcome every budget with equal respect.
