Is this an S.O.B.?

Sorry, don't know how to do pic's . . .
But the front panel has 2 inouts (1 & 2),controls are Volume 1, Volume 2, Master, Treble, Bass, Middle, Presence..
I thought it had a "limit" control?
Is this a variation?

Sounds like a 50+ Caliber to me. A 50+ Cal has only two power tubes.
If it has four power tubes and NO effects loop, it might be an SOB. I think.

I fairly certain that SOB's were made with and without limit controls. That said most of the SOB's I've seen have "SON of Original Boogie" written on the back.

Yes, that's an S.O.B.

They were made with and without the Limit control on the front, and the ones without have a Presence control instead.
