| Does anyone know what changes were made to this preamp over the years? I have one about 10 years old that must be the first run, and another made in 2012 that says Rev 2 on its sticker. That implies there was a Rev 1. Curious, as they both sound the same, just what Ovation did in revising them. |

Location: Utah | As someone who spent a decade working with electronics and specs, but not Ovation stuff, the Revision usually indicates a minor change which does not affect form, fit, or function. The difference could be a different circuit board to accommodate newer electronic parts. Older technology semiconductor parts can become obsolete in a couple years or so. Or a sole-source part becomes unavailable. A ten year span in commercial electronics can be several generations of technology.
In the commercial world (as opposed to military aerospace where I worked), a revision could possibly imply a different eq or other more significant change. It would be interesting to get a definitive answer from the factory on what the changes are. Your two preamps should be drop-in replacements for each other, though. |
