[2] He was a low key but reliable offensive player who could turn the game around with his deadly shooting both from the perimeter and, in his later years, from three-point range.
Before the start of the 1985 Third Conference, Guidaben was traded to Manila Beer in exchange for Ramon Fernandez, thus ushering a bright new era for the team still in search of a championship.
In the 1986 Reinforced (First) Conference, Tanduay, now led by himself and Fernandez with supporting casts point guard Willie Generalao, forwards Jayvee Yango and Padim Israel and imports Rob Williams and Andre McKoy, finally won its first ever PBA title.
With his steady play and clutch shooting, he led Tanduay to its second title the following conference, capturing the All-Filipino championship at the expense of Robert Jaworski and Ginebra San Miguel.
Tanduay would fail in its bid for a grand slam as Ginebra easily won the Open (Third) Conference, thanks to its devastating import combination in Billy Ray Bates and Michael Hackett.
