What are the white switches near the top for?
Well, on an old SVT there are 5 rocker switches. The first 3 are for channel 1. The first one's Ultra Lo, which is a low frequency boost, the second's a 3-way frequency selector for the midrange (220Hz, 800Hz and 3000Hz) and the third's Ultra Hi, which, as you might guess, is a high frequency boost.
The other two are Ultra Hi and Ultra Lo for the other channel.
Thank you very much. Occasionally, I have to play using an old Ampeg and I always wondered what those switches do.
