Probe Plus is a record label based in Liverpool, England. It was founded by Geoff Davies, an enthusiastic promoter of small, unsigned bands, who describes the label as "Music to drive you to drink". The label was started in May 1981, its first release being the self-titled debut EP by Ex Post Facto. For years the label was based in an office above the Probe shop in Rainford Gardens. Due to a change in building ownership both the shop and label were forced to move and Davies set up office in his house. After marrying Anne in 1999, they moved house and he continues to run the label from there.
