Faustine Amplifiers founder and chief
builder, Tim Gregoire, is a seasoned guitarist and vintage electronics
enthusiast. His interest in
electronics began as a child in the '60s when he would raid the dumpster
of the nearby Radio & TV shop and
attempt to "build" things from the discarded parts.
Tim began playing guitar in 1968 and started using tube amplifiers
in 1973. His early interest in
electronics inspired him to study industrial electronics and he has
enjoyed a career as an electronic technician since 1978, with a brief
hiatus in the early eighties to pursue a music degree and work full-time
as a gigging lead guitar player and teacher.
Over the years, Tim’s career has steered him in many
directions… from building submarine control systems, racing computers,
and mobile power distribution systems for movie studios to his employment with JPL / NASA in Pasadena, California, where
he worked from 1989 to 2009. |

Evolution of the Phantom: (as
told by Tim Gregoire)
|
|
|

|

The
Faustine Phantom VRA (Variable Reactance Attenuator)
|
|
|
|
got its start as a challenging electronics project back in 2000.
I had recently bought a new amplifier and after swapping some tubes and
making some minor electronics tweaks, I had a tone that I quite liked.
Trouble was, I had to turn the amp up pretty loud to hit the “sweet spot”,
which made it unusable for many situations. I put a volume pedal in the FX
loop as a pseudo master volume, but it removed the output circuit from the
sweet spot equation when I turned it down. The amp also had an “overdrive”
channel, but I preferred the kind of drive I get with the power tubes
cooking. I knew I needed an attenuator to get the kind of tone I wanted at
usable volumes. |

I had some experience with attenuators in the past. I owned a Scholz “Power
Soak” for a few years in the 80’s. It came in handy for gig volumes on
my Carvin X amp, but it changed my tone for the worse at anything more than
a couple of clicks on the dial. I sold the Scholz Power Soak in 1989.
So here I was, 11 years later, looking for another attenuator.
There were a few options available… the THD Hot Plate, Marshall Power
Brake, and the Trainwreck Airbrake. They all looked like well engineered
devices and they had garnered some pretty good feedback, but I couldn’t
afford one. Randall Aiken (of Aiken Amplifiers) was on the verge of
releasing an attenuator called the “Afterburner”. It appeared to me
(from the specs on his website) that it would be the “ultimate”
attenuator. So, I decided to sock my money away and wait for it. But, after
waiting for several months and seeing no Aiken attenuator on the horizon, I
decided to build my own. I had years of experience as a senior electronic
technician, most of that in the aerospace industry. I had built, modified,
and repaired my own amps, FX, and electronic gear for a long time and I
figured “it’s just an attenuator… how hard could it be?" I did some
research and got to work in the fall of 2000.
By the spring of 2001, I had my attenuator finished! It was
conservatively rated for 150 watts RMS at 8 ohms impedance, had a bypass /
engage switch, selectable
attenuation levels ( -3, -6, -9, -12, -15, and -18dB), a continuously
variable control for low power adjustment (from -18 to -28dB) and selectable
speaker “modeling” (Celestion G12M or Jensen P12N). It also had a “cabinet-voiced”
line output circuit with adjustable transformer-isolated balanced /
unbalanced outputs, mid-contour control, and a
ground-lift switch. Every feature that I thought I would ever need, I built
into that attenuator. And I did it all with passive electronics
(i.e. no power), which was no easy task with the
"cabinet emulation" circuitry. It took a lot of calculating,
prototyping, testing, SPICE modeling, and more prototyping, but I
was adamant about not having to plug in to AC power. I
didn't want the equivalent of a "kitchen
appliance" sitting on my new combo amp. The unit was already half
the size of a toaster anyway (see pics)!

The attenuator was housed in a heavy
duty enclosure with massive heat sinks and weighed around 10 pounds…
it was built like a tank! This was the very first “Variable Reactance
Attenuator” and I thought it sounded great with my new amp. It wasn't
pretty (I labeled the controls with a pencil) and it was
huge, but it did the job very well. In fact, compared to my last attenuator (the Scholz
Power Soak), it was quite an improvement. I thought I might be able to
market it.
I put
together a bill of materials for a “production” model attenuator. The
parts alone cost over 400 dollars! That didn’t include any metal
fabrication costs or labor costs for assembly. Even with all of the advanced
features that I had built in to it, who would pay that much money for an
attenuator? That took the wind right out of my sails. So, I used my
attenuator whenever I had a jam session with friends or the occasional gig,
but when I took a few years off from playing, the attenuator went in the
closet with the amp.

2005… I started building some of my favorite tweed amps… Super,
Bandmaster, Pro, Twin, but with some of my own design twists. After building a couple of tweed amps and hot-rodding them a
little bit, I dug my old attenuator out of the closet, hooked it up to my
modified tweeds, and together they were
a thing of beauty!
So, I stripped my attenuator down to a few
essential elements, lowered the power rating and attenuation range, stuck it into a little box,
mated it with my hot-rodded tweeds, and Faustine
Amplifiers was born. When people started playing my amps, I kept getting comments about how “transparent”
the on-board reactive attenuator was. I was told repeatedly that the
attenuator sounded better than anything else on the market!

It's funny... I wasn’t aware that my attenuator
design was anything special. I didn't intentionally set out to design and
build a better "mouse trap" (so to speak), since I didn't have any
other attenuator on hand to compare it to.
I just designed it the way I thought an attenuator should be designed. It lowered the volume and didn’t change the
tone in the process; isn’t that what attenuators are supposed to do?

When I visited Tone Merchants in Orange, California for the first time, I
knew I had found the right dealer for my amps. Tone
Merchants manager, Noel Evangelista, really liked my modified tweed designs
and was particularly impressed with the on-board attenuator. Over the
next several months, I got a few requests from Tone Merchants and their
customers to build a “stand-alone”
version. In May of 2007 when fusion guitarist, Greg Howe, expressed an interest in getting
a custom-built reactive attenuator, I started to take the idea seriously.
Greg and I made plans to collaborate and develop some ideas for a new
attenuator. I
built Greg a simple no-frills 50 watt prototype, as a proof of
concept. I shipped it off and he liked it, but
then he got very busy for several months... putting together a band, rehearsing new music,
recording an album, and doing a tour. We lost touch. I figured that was the end of that.

I built the
next prototype in November 2007 with all the frills; the VRA-50, a 50 watt
attenuator with selectable impedance (2-4-8-16 ohms), selectable load type
(resistive-reactive), two parallel speaker outputs, and a “cabinet-voiced”
, transformer isolated, balanced line- level output with a midrange “contour” control, adjustable
output level, polarity switch, and ground-lift switch. I took this
second prototype to Tone Merchants in early 2008 and everyone loved it. Noel requested
(once again) that I build some “boutique”
attenuators for their shop. I was still unconvinced that it would be
economically feasible, considering the steep price to fabricate the units,
but Noel was persistent, assuring me that “people who want the best are
willing to pay for it.”

Shortly thereafter, in August 2008, new Tone Merchants
owner, Rob Navarrette, inquired about placing an order for ten units based on Greg
Howe's recommendation. However, I needed to design a more robust, commercial
unit that could be used with a “dimed” 100
watt head. I had my previous design from 2001 that could handle 150
watts easily, but I considered the size and weight to be unreasonable.
I liked the size of my VRA-50. You could toss it into a gig bag with
your FX and guitar cables and it would easily fit on top of any amplifier,
including small combo amps. I was really determined to keep the 100
watt VRA roughly
the same size as the VRA-50 (about as large as a THD Hotplate), so with those constraints in mind, I got to work.
Meanwhile, in September of 2008,
well-known amp
guru, Dave Friedman, demoed the 50 watt prototype (which my wife had since named
"the Phantom", for its sonic invisibility) and he
was so impressed, he proclaimed it the "best new attenuator he had ever heard" on
a popular internet guitar gear
forum. That same week, guitarist Peter Thorn
auditioned the VRA-50 "Phantom" and confirmed Dave's impressions. That changed everything. When
Dave and Peter speak, "gear-heads" listen! I was still a couple of months
from finishing the first 100
watt prototype, but people began contacting Tone Merchants
immediately,
putting down deposits, and
getting on a waiting list. Dave and Peter’s endorsements were soon followed by praise
from other well known guitarists, amp builders, speaker builders, and tone aficionados.
The word got out and the waiting list got longer. I've been trying to catch
up ever since!

100 watt Phantom, Revision A
November 2008
This first prototype was a
big re-design from the VRA-50, but it had some hold-overs, such as the
selectable resistive-reactive load switch and a variation of the
multi-impedance selector circuit (without the 2 ohm option). Gone was the
"cabinet voiced" line out circuit with bells and whistles,
replaced with a basic Dave Friedman designed variable line-out circuit. |

100 watt Phantom, Revision B
December 2008
The attenuator switch
range was expanded and the resistive-reactive load switch was changed
to engage-bypass. The low power Variable Control range was
changed ( -12 to -26dB). The electronics in this Rev.
B prototype were upgraded to the Rev. C circuit in January 2009, in
time for Greg Howe to use it for his NAMM week concert at Tone Merchants. I
still use this prototype (with no external heat sinks) for gigging with my own 40 watt
amps. It hardly breaks a sweat! |

100 watt Phantom, Revision C
"silver surfer" model.
February 2009
The Rev. C circuit was
essentially identical to Rev. B but the Variable Control range was
expanded to go down to zero output (LOAD). A mod was also made
to the reactive load circuit to work better with 7 string and Drop-D
tunings. This third prototype was
housed for a short time in this "unfinished" newly designed aluminum chassis
(with external heatsinks) for testing and
fit-checking. This was the last prototype (and the final circuit revision)
before the "production" model was fabricated. |

100 watt Phantom Dx, Revision C
The
"production" model
April 2009
The first 15 units had laser
engraved panels which have since been replaced with silkscreened
panels. The heatsinks have also been lengthened slightly on later
models. There are already a couple more minor improvements
planned for the third production run. Phantom Dx, Revision D? |

I want to acknowledge some
of the great people who have contributed to getting the Phantom launched
through their ideas, observations, feedback, testing, and discerning
ears. Kudos to Noel Evangelista, Greg Howe, Dave Friedman, Peter
Thorn, Carl Verheyen, David Torn, Rob Navarrette, and the
rest of the "Tone Merchants Gang" (JMR, Jimmy Ray, Carl &
Henry). And a very special thanks to
all of the customers who have been so generous with their encouraging
feedback and who continue to spread the word!
