c1973 WEM Power Musette Mk II, courtesy of Jim Hendricks, Kent, England.
The Power Musette is a version of the Dominator, identical except for having
a twin-cone 12" speaker which supposedly makes it more suitable for use with organs and accordions. The Power Musette Mk I co-existed with the Dominator Mk
II : the Power Musette MkII with the Dominator Mk III - for more details see the Dominator pages.
A Custom 15 Musette Reverb was made in the mid-60s, a version of the Custom 15 with reverb and a "middle range curved cone" speaker.
