Can someone help me with this Bass guitar

Pascal Quinson has been a luthier since 1987. He started out in Toulouse, at quai de la Daurade. He was partly self taught but also learned from luthiers in Paris. Now works in Montauban where he makes violins, lutes and classical guitars.

Phoenix Mandolins was founded by Rolfe Gerhardt who started building mandolins in the early 1970s. He was self taught and started by using some plans from Benny Cain, and observations of a local Gibson Loar F-5 to make two reproductions of a 1920s Gibson F-5 mandolin. He then began experimenting with mandolin design and this was the start of Unicorn mandolins. Rolfe made 149 mandolins before selling Unicorn to Dave Sinko in 1980 who eventually moved Unicorn to Nashville. Although Rolfe had agreed not to make mandolins for ten years as part of the sale agreement of Unicorn, he didn't last that long and was building mandolins again in the late 1980s using the Phoenix brand name. His new design had a fixed graphite-epoxy neck stiffener which eliminated the need for an adjustable truss rod. He also refined the body shape using a two-pointed cut-away design, and incorporated a radiused fingerboard and finger-rest.

Otentic guitars are hand made by Rene Meulmeester in the Netherlands from high quality components. Otentic bodies and necks are CNC machined from selected wood and their pickups are handwound to Otentic's specifications. All instruments are finished using oil - no lacquer is used on the body or neck. Otentic instruments are usually Fender style electric guitars and basses.

Suntech was an electric guitar and bass brand from the late 1970s to 1980s. Suntech instruments were made in Japan for overseas distribution. Suntech guitars typically good copies of Fender, Gibson and Rickenbacker models - but there were also some nice original variations like Suntech's Limited Edition neck-through version of the stratocaster.
