Paris Pro Regular White by Moshik Nadav Typography. Beautiful, suggestive, disappearing hairline stokes of the 'S' makes the connecting swash to the 't' seem a little weighty as well as the slightly squared terminal verses the razor sharp crossbar.
SECONDARY RESEARCH: This is my favourite of all of the SK logo designs I have seen. I think that there are transferable elements that could be employed in the SSK project - maybe changing the 'S' for a rope-like design.
Guitar Studio Logo - Very creative use of the guitar to form both the 'i' and an 'S' in the title. The plain white against black works very well for the studio, displaying a professional aspect while remaining fresh.
