Schematic for 79 Sabre

[ampolicious]

I have search the net with no luck. I got a Sabre here with the three toggle switches. Someone did some work on the bass and now the phasing switch does not work. I have tried to reverse engineer it and my little pea head explodes.

anyone know where I can find a schematic for this thing?

It's probably working nomal:

If you flip it one way and have full powerful sound, then flip it the other way and it sounds very low powered and ultra thin, then it's working just like it was made. It was a lame feature that doesn't work with basses like it sort of does on guitars.

See if this helps.

I have the schematic wirings if needed.
