Most of the ADS speakers I've had, which is most of them, had a finish on them that made it necessary to remove all that finish before anything like Watco or Howards was applied.
These didn't warrant that. I considered sanding off the finish, but the scratches were minor. Watcos made a big difference. These cabs looked like nothing had been done to them since they left the factory.
Maybe down the line I'll do a complete sanding to the veneer and refinish.
