The solid state and tube versions of the Vox Pacemaker had similar control panels and features. The tube Pathfinder control panel is shown above, the solid state Pathfinder is shown below.
The Pathfinder amp had a single channel with two 1/4" inputs and tremolo. The tube Pacemaker had a rectangular frame around each of the control names on the upper control panel. Later versions of the solid state Pathfinder amp added an "E-Tuner" function to the lower control panel of the amp.
