If you own a tonewheel Hammond organ, you have come to the right place.


We love everything about them and if
you have one that needs some TLC,
the best solution is to use someone
truly passionate about their craft.


Geoff Williamson of Doppler Audio
is that person.


Doppler Audio specialises in servicing, overhauling and fully restoring tonewheel Hammond organs.


We also service and restore Leslie tone cabinets and vintage tube amplifiers.
