A very early Avalon 737 came in for a routine service this week.
Its owner, a local chap is an old school buddy of Wyn Morro, the man behind Avalon Design

He reminded me that it was this very Avalon 737 that was the first to have a fast attack modification performed on the compressor. This followed on from from his request to Wyn for a shorter minimum attack and the notes on how to do the mod being sent back to the local tech, me.
As the Australian authorised repairer for Avalon Design it would transpire that I was seemingly the first to perform what has gone on to be known as the Babyface mod.
