silverface vibrolux reverb trem mod

[sweetman Improvements]

I have a 74 vibrolux that someone at one time installed a mod or something that only allows the trem effect to work when the volume knob is pulled out,and even then it seems really weak and like garbage.Shame because my helper has made some improvements of late and the amp sounds quite nice now.The pot itself does not look original to the amp,and I did'nt think they were using push/pull yet anyway till later.Can anyone suggest anything?Im looking to just be able to activate with footswitch and adjust with the pots.Any advice would be a great help.Thanks..

Do we know if the LDR unit is any good? Also, pics of the amp's insides would help just to make sure there's no wiring errors.
