Wesley United Methodist was formed in 1958 when Baker Memorial Methodist and First Methodist Churches merged and built a new building. The churches' former organs, a George Hutchings tracker of 1896 and a 1917 Estey electric action instrument were combined on various electric chests including those of the Estey. The pipes from the two organs and others, new and used were included. In 1991, the old Estey console was replaced with a new one using solid state technology. By 1995, the old chests were giving problems and the church decided to rebuild the organ. The Andover Organ Company was selected.
The design for the "new" organ had some unique challenges. The organ was to occupy the former chamber on the left side of the chancel. The chamber itself had a trapezoidal shaped floor plan and the ceiling angled down sharply toward the rear of the chamber on the second level. The bottom pipes of the new 16' Violone were literally too tall to stand in the chamber. Our solution was to place as many pipes as possible in a new facade, replacing the existing screen. The 16' Violone, except for the bottom 4 pipes and the new Great 8' Open Diapason were placed in the new facade. New manual chests were built of the slider type with magnet pull-downs as the organ was to retain its electric action. New unit chests were built for the two reeds and for the 16' Bourdon, all of which were to be unit stops. The old pipes were rebuilt, rescaled and revoiced along with new pipes for the Mixtures and other stops. New solid state switching and expanded combination action by SSLL was installed. The organ has MIDI capability and a sequencer for versatility.
The case design was by Donald H. Olson, the mechanical design by Jay Zoller and the Tonal design and finishing by John Morlock in consultation with Tom Jenei, organist of the church.
