The  history  of  the  MSS-10  begins  at  Martinsound  where  a  passion  for  excellence 

in audio has existed since the founding of the company. Martinsound started out as 

a  multi-track  recording  studio  and  grew  into  a  highly  successful  corporation,  with 

divisions that include the development of professional audio products. Martinsound’s 

most acclaimed development is the highly regarded Neve™ Flying Faders™ automation 

system.  Believing  that  Flying  Faders  was  just  a  beginning,  Joe  Martinson,  owner  of 

Martinsound, dreamed of developing a range of products that set new standards for 

sonic quality. Being a true visionary, he fixed his sights on the goal, and began surround-

ing himself with a team that would help him to accomplish his intent, little realizing the 

years, money, and resources that would be required.

Working for Martinsound since 1980, Shawn Micheal has held the various positions of 

chief recording engineer, studio manager, co-developer of Neve Flying Faders, and cur-

rently as Vice President of Product Development. Shawn still spends a lot of time in 

the studio, working as a free lance recording engineer. A favorite pastime for Joe and 

Shawn was spending countless hours discussing the sonic attributes of the equipment 

they used, and how to pick equipment whose coloration best matched the source being 

recorded. The discussion always ended the same: Wouldn’t it be great to hear a source 

with no equipment coloration at all! This was a dream that Joe and Shawn shared for 

well over a decade.

Also  working  for  Martinsound  in  R&D  was  Toby  Foster,  a  gifted  and  respected  free 

lance recording engineer, as well as a very talented design engineer. A man of action, his 

thoughtful design work is seen in custom consoles built for some of the most respected 

studios in Los Angeles. His enthusiasm for great reverb helped him to introduce MAR-

TECH’s EMT 140 Upgrades, which resurrected and updated plate reverbs all over the 

world. But Toby’s real passion is truly in great microphones and getting their output to 

tape in as pure a form as possible. His involvement with some of the world’s top engi-

neers and producers put him in the unique position of knowing exactly how far the enve-

lope of audio excellence needed to be pushed.

Meanwhile, in the mid 70’s, a brilliant young design engineer, named Bud Wyatt, was 

working at Producers’ Workshop recording studios. His quest for sonic excellence led 

him  to  some  interesting  amplifier  research  that  proved  to  be  the  beginnings  of  the 

D2024C, the amplifier used exclusively in the MSS-10. Later, Bud worked for Sheffield 

Labs, where the fine art of listening was refined to the highest degree. This was a valu-

able time for Bud, developing and working with only the finest sounding equipment. At 

the end of 1993, Joe, Shawn, and Toby approached Bud to help them realize the dream 

that they had held for many years: to develop a pristine sounding, tube microphone pre-

amplifier.
