Vintage Sound Vintage 15 Head - Ostrich
- OPTIONAL BIAS POINTS
The Vintage Sound Vintage 15 is essentially an all hand-wired, all USA made, super-modified Fender Princeton Reverb. It's based on the "blackface" Fender Princeton Reverb (AA1164) used from 1964-1967, but with several major and significant upgrades (read more below).
The Vintage 15 has a decent amount of warm, clean headroom for a 15 watt amp. As you turn the volume knob, it doesn't start breaking up until about 4 or 5 on the dial. It will easily hold it's own again any typical Deluxe Reverb out there. Players from all genres LOVE this amp - from Blues, to Country, to Rock!
Blah, blah, blah... We could go on and on with "salesman speak" as we like to call it, but let's get right down to the interesting stuff that really matters.
So exactly what are these upgrades, you ask?
1) The reverb circuit is vastly upgraded. The stock reverb on a Princeton was a small 9" pan spring reverb. The Vintage 15 uses a large 17" spring reverb pan that's the same size as the one used in the Twin Reverb! The reverb circuit also includes a very nifty reverb dwell control on the rear of the chassis for varying the decay time.
2) A "MIDDLE" tone control has been added that Princeton Reverb amps did not have. This addition does absolutely nothing to hurt the integrity of the circuit or tone. The original Fender circuit actually had a fixed mid tone was set permanently at 6.8k. Vintage Sound removed this resistor from the circuit and replaced it with a much more versatile 10k potentiometer. The result is you now have the ability to adjust this frequency range without compromising the original tone. If you want it to sound precisely like a blackface Princeton Reverb, just turn the port to around one o'clock on the dial and you're there. You want to scoop the mids a touch, pull back. Warn the tone a bit, turn up.
3) The Vintage 15 utilizes a 5AR4 rectifier instead of a 5Y3. This bumps the wattage a bit (from approx 12 watts to approx 15). Accordingly, Rick added grid and screen resistors (as seen in the Black Face AB763 circuitry). This gives the transformer more protection in case a tube fails catastrophically. Wait! You say you want the sound of a 5Y3 instead? No problem! Just swap it out. Easy as pie.
4) The addition of a Standby Switch. The original Princeton Reverb didn't have one. This one does.
So, as you can see, the Vintage 15 has lots of upgrades to the original Princeton Reverb circuit without adversely affecting the vintage tone. As well, all Vintage Sound amps are point-to-point hand-wired using top quality filter caps and electrolytics, carbon comp resistors, Orange Drop tone caps, solid core push back wire, and custom transformers that are hand wound in the USA.
A note about the original Princeton Reverb
A very good question we get asked from time to time is why all the upgrades? Didn't Leo Fender get it right back then? The answer to that is, "well, yes and no." We'll elaborate...
So, while the PR circuit is a fabulous one, let's not forget what was going on with Fender back then. The company had already been around a number of years and in 1964 it was being prepped to sell to CBS (which happened January of 1965). The Princeton Reverb was a student amp, and never was meant to be a major player among gigging or recording musicians. It was a practice amp with reverb. In order to make it a successful model financially, it had to be mass produced as cheaply as possible. Now, with that said, everything was built better back then. We didn't have printed circuit boards or cheap foreign labor to construct amps from, so even the "cheap stuff" was actually pretty darn decent. Still, it was mass produced to hit a price point. That meant leaving bells and whistles out of the design as much as possible. As luck would have it, the amp sounded great, and it has stood the test of time all these years. Because of this, it's very appealing to have a "decked out" version with all these great bells and whistles. Enter the Vintage 15!

What are the differences between the Vintage 15 and 20?
The Vintage 20 is precisely the same as the Vintage 15 with the following exceptions:
1) The 20 has larger power and output transformers, bringing the output to 20 watts yielding noticeably more clean headroom.
2) As well, the Vintage 20 can alternate between 6V6 and 6L6 power tubes. Overall, the 6V6 tubes are recommended. The 6L6 tubes will deliver slightly more bass, but will be a bit more stiff in response. Stiffness isn't a bad thing if that's what you are going after, but the majority of people will prefer the slightly softer response of the 6V6 tubes. Naturally, your mileage may vary.
It's certainly a worthy upgrade if you plan on swapping out power tubes much.
