the band i joined in july already have a rotosound endorsement, and have had for years, a stage make up endorsement, a pick endorsement ( even though i rarely use the things!).
When i joined i sent a speculative email to Dean uk asking about their criteria for endorsement giving some background about myself, and hey presto, once i got an email back from them (within a couple of days), they gave me the details, i sent the required info, and the rest , as they say, is history!!
