"G2D Started commercially selling
pedals in 1999. Our serial numbers are written on the base of
the pedal as well as on an internal label, these numbers are
kept on our database and people are welcome to email us and we
can pretty much tell them to the Year/week their pedal was made.
There is also a "History" link on our website that shows the
origins of G2D." [Source: Grant Wills, G2D Limited, email,

From this site the story
appears to be" The 4 digits of the serial number before the "E"
indicate YYWW where YY is the digits of the year (01 for 2001)
and WW is the work week (01-52) in which the unit was
manufactured".

Geib |
Geib was a cabinet maker in
Chicago pre World War II. They made cases for Gibson
guitars. According toGruhn's
Guide To Vintage Guitars, Gibson made
amps with chassis by Lyon & Healy and cabinet by Geib, and
these amps were made with Recording King brand. Kalamazoo
made amps with a Geib medallion on the side [Source:
Pre
WW II amps] so suspect the Recording King and Kalamazoo amps
came from the same line.
According to
Vintage Guitar a 1936ish
Supro/Bronson amp
was made in Chicago by Chicago Electric, with
cabinets built by Geib.
The following photos were sent to
me by Pat Maguire for help.
The
amp was purchased in Conway N. H. in 1997. The proprietor
of the pawn shop told Pat it was
pawned by some member of The Smashing Pumpkins.
There are no other identifying marks except for the Geib
medallion. The silver foil sticker
inside the back next to the Geib badge
states: "Licensed by Electrical
Research Products Inc. under U.S.
patents of American Telephone and Telegraph Company and Western
Electric Company Inc. for use only in
public address systems, phonograph
distribution systems, systems for distribution from a radio
broadcast receiving set and systems
for distribution from musical instruments."
If anyone is able to add more
please let me know.

? - 2007. Harvey Gerlitz made the
Revelator dual amp. It appears from a comment made by a
dealer on the
Gear Page that Harvey stopped making the Revelator in
2007. The web site is no longer operating as at Jan 2009
with the last wayback machine page Jan 2008 (the first 1999).

Germino |
Greg Germino
worked with Mojo Musical Supply in January 2001 and late
that year was commissioned to build the Mojo "Tone Machine"
amplifier consisting of a run of 30 pieces. In
May 2002 Germino Amplification began with the first production
pieces being shipped to dealers at that time.
Greg builds tube amps and cabs in Graham, North Carolina,
USA.
Germino
amplifer dating
"All Germino
amplifiers have a date written on the chassis of when they were
built.
Very early 2002 this was written in permanent maker on the top
or side of each chassis. Additionally each back panel was
engraved with a three digit serial number.
By 2003 I was
applying a label which I hand signed and wrote serial number
corresponding to the back panel s/n. This has continued
throughout production.
In early 2007
beginning April I began using a different chassis with new
panels that use reversed silk screened lettering/numerals on
clear perspex that was painted gold after the lettering. This
gives the exact appearance
of the old original plexi panel amps.
The earlier
panels were gold acrylic that were reversed engraved and
engraved lettering painted black on the backside.
Beginning April
2007 along with the new panels a serial numbering system came in
to use with the last two digit os the year being used followed
by the serial number sequence of a given model. Ex: Club 40 S/
07 075,
indicating built 2007 and the 75th piece in the run.
2002 used a
very large Germino Badge logo for the first 10 pieces of each
model in production. This style logo was followed by a smaller
plexi block logo with "hobo" font. This was used thru 2005.
Beginning 2006 the script
logo came into use as you see currently.
I keep a build
sheet and voltage chart for every amplifier I have made. This
has voltage information as well as s/n and date of manufacture.
Early 2002
into 2003.
