Being a fully qualified electrical engineer, Rien Theunis has been repairing and modifying equipment for musicians, distributors and even competitors for more than 40 years.


Whether you want the valves in your amp, the speakers of your P.A. or the pickups in your favourite guitar replaced. WMS is your best choice; quality work for a great price.



As mentioned, we have a truckload of experience in this field; only a few years ago at a music fair in the south of Germany we spotted a band playing over a P.A. we built in the late '60s!
