The Vintage Sound Vintage 40mvp is here!

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. The Vibroverb was a 1x15, the Pro Reverb was a 2x12, the Super Reverb was a 4x10, and the Bandmaster was just a head.

Notice anything missing?

Right! Fender never made a 1x12 combo! Hard to believe...  They had an AB763 that was a 1x12, but it was only 22 watts (Deluxe Reverb). If you wanted that fat, thick 6L6 tone, you HAD to use one of the configurations above.  The Vintage Sound 40mvp addresses that, but with bonuses!  We'll get to the bonuses later. 

Of course, these original combos were large. Being a single 1x12 combo, the 40mvp is housed in a smaller Deluxe Reverb sized chassis. The cabinet is also sized like the Deluxe Reverb, but we made it one inch taller, and one inch deeper for better bass response.

The faceplate of the Vintage 40mvp is also smaller, leaving no room for the Normal/Bright switches. To address this Vintage Sound uses a high-end push/pull pot for the Volume control. By default it uses Normal voicing, and when pulled it engages the Bright voicing. 

So what about these bonuses?

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 40mvp 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 40mvp also comes with external bias points for re-biasing the output tubes after changing them.

So, what do you end up with?

Why the WGS G12C speaker?  The G12C is essentially WGS's take on the vintage Jensen C12n, but with a few refinements, such as a bit more touch sensitivity, and an overall warmer tone. Warehouse Guitar Speakers are made here in the USA and not in China like most of today's Celestions.
