The Anomalous Rev G

This Neural DSP Quad Cortex capture pack features one of the rarest configurations in Dual Rectifier history: a Mesa/Boogie Dual Rectifier Revision G (Serial #3515) with Revision F transformers. This 1994 anomaly combines a Rev G circuit board with the earlier 562100 Output Transformer and 561136 Power Transformer—normally found in Rev F models—housed in a Revision C chassis.

What Makes This Special

The Revision G is known as the final evolution of the 2-channel Dual Rectifier, produced from 1994-2001. Most Rev G amps received dedicated Rectifier transformers from Schumacher, but Serial #3515 is an exceptionally rare exception: it shipped with the earlier Mark-series transformers (562100 & 561136) that gave the legendary Rev F its tighter, more focused character.

This unique combination delivers:

• Rev G's enhanced gain structure and darker voicing
• Rev F transformer tightness and articulation
• Best of both worlds: massive gain with exceptional clarity

Why Collectors Love This Amp

Revision G Dual Rectifiers are already sought-after as the final and most refined 2-channel model. This particular amp—with its rare transformer configuration—represents a transitional moment in Mesa's manufacturing history. The combination of Rev F transformers in a Rev G circuit creates a tonal sweet spot that's impossible to find in standard production models.
