Vintage 40 2x12“ MV 

(Pro Reverb)

The Fender AB763 40-watt circuit is behind some of the most coveted Fender tones of all time. This dual 6L6 blackface circuit was in the Vibroverb, Pro Reverb, Super Reverb, and Bandmaster. Fact is, 99% of the difference between these amps was speaker configurations.

When modifying vintage circuits you have to be very careful to do so in a manner that does not alter the tones in a bad way. The Vintage 40 includes some well used mods that bring more to the table than the stock circuits.

1)Channel 1 on all Fender style amps (normal channel) has an identical tone stack to Channel 2 (vibrato channel). The only difference in Channel 1 and Channel 2 is that Channel 2 has reverb and vibrato effects. Because Channel 1 is mostly unused and is a redundant channel, it's been re-voiced with a mild high gain mod. This makes Channel 1 perform as if using a compression pedal but with a much more natural tone because the effect is part of the tube circuitry. The channel is fairly clean when picked lightly and becomes more compressed with pick attack and volume increase. The reverb and vibrato effects are also brought into Channel 1 giving the player two different channels, both with effects, making the amp more versatile. 

2) The rectifier is switchable between Solid State and 5AR4(GZ34) Tube Rectified. This allows the amps response to be quicker/stiffer with little to no sag, or softer with sag.

3) Included is a custom reverb dwell control on the rear of the chassis. It comes in handy for adjusting the amount of decay the reverb has.

4) Another mod is the Diaz based tremolo mod and a newly designed oscillator unique to Vintage Sound. You'll notice the Vibrato has the ability to be slower than stock Fenders. The vibrato being too fast was always a complaint people had with vintage Fender amps. The other advantage this gives is when you turn the dial all the way down you switch off the vibrato circuit, bypassing it and leaving you with a cleaner, more pure signal. The result is a more present tone and a bit of a bump in volume. Furthermore, with the older Fenders you hear a "ticking" sound with the vibrato. This is caused by several design flaws in the original circuit allowing the LFO signal to leak into the audio path. These issues have been addressed with this specifically designed photo-cell tremolo, better routing of the wires, superior components, and filtering of the oscillator output.

5) Each Vintage 40 also comes with external bias points for re-biasing the output tubes after changing them.

6) The new MV version 2019 has a modified „Trainwreck“ Post Phase Inverter Master Volume WITHOUT any tone loss!!!
