Mike Johnson Custom

Hand Made in England

Introducing the latest innovation from Mike Johnson Custom


3rd November 2020
Over the last 25 years Mike Johnson Custom has continually developed the the 4th valve rotary system on compensating tubas. Not simply replacing the 4th valve with a rotary valve MJC has developed the whole system to perform in a superior way.
Now after long design, planning, and negotiation with one of Germany’s premier rotor builders the plan is in place and the valves are being made.
