n the early days, all of Mosrite’s guitars were hand made custom orders. Mosrite could well have remained a small company, making guitars by special order, but Semie Moseley loaned a guitar to Nokie Edwards, of the Ventures, to use on some recording sessions and within a year the Ventures had signed an endorsement deal with Mosrite.
uring this same period of time, Glen had struck gold with "Gentle on my Mind", "By the Time I Get to Phoenix" and "Where's the Playground Susie", being seen playing these songs with an assortment of Mosrites. In the summer of 1968, Glen hosted the The Summer Smothers Brothers Show, later renaming it "The Glen Campbell Goodtime Hour". Glen played Mosrites during the replacement show, until a small fledgling company, called Ovation, signed him to promote their guitars in late 1968.
len had to like the D100 as much as we saw him with it around 67. Semie owned the rights to Dobro at the time, so he married the dobro resonators to a Mosrite Celebrity body, with DeArmond pickups. It appears that Glen's Californian had only the "Dobro" label on the headstock (some D100's had the Dobro and Mosrite decals on the headstock).
len posed with it for the front of the "Hey Little One" album
nd appeared on several shows with it (never plugged in). Here he is playing Gentle On My Mind
eedless to say, orders for Mosrites skyrocketed. The company went from making 20 or 30 instruments a month in the early 1960s to nearly 1000 instruments a month at the peak of production in 1968. Semie even advertised in 68, using Glens popularity to promote his guitar company. Glen was seen in the ad playing the D100 Californian Model.
nce Charlie Kaman signed Glen to endorse Ovation, the Mosrite D100 disappeared from his appearances.
