DMB Pedals |
DMB Pedals is located in Oklahoma
City, Oklahoma. It is a two man operation consisting of Mike
Blakemore and Daniel Minton.
"We started in 2006.
Dating DMB effects pedals
We have an interesting serial number sequence.
It will include the date the pedal
was made in 6 number format, and then a 4 letter format for how
many pedals where made that day.
So, if one was made today it would
be: 0525100001
If one was made on October 31, 2008, and it was the 4th pedal to
be made that day, it would read: 1031080004
Make sense? Since this year, we have started including what
number the pedal is as well, like #135 for whichever pedal it
may be, but this does not give a date.
Pedals are usually signed or
initialed by either Dan or me once we have inspected them. [Source: Mike, DMB

About Dockery Amps (from Wayback
Machine)
Mission
My mission is to give the competition a run for their money by
selling high quality kits for great prices. I only use the best
quality components and I provide great information to help with
the assembly of these kits, such as well thought out and
intuitive layout and schematic diagrams that are easy on the
eye. Their are many articles on this website to help anyone
learn the essentials of tube amplifiers. This is what I offer to
my customers, and I take great pride in what I offer.
Loy Dockery
I started this business in February 2007. It's been a very
satisfying venture for me. I am scheduled to graduate with
Bachelor's of Science in Mechanical Engineering May 10th, 2008.
I love to dabble in many different things such as electronics,
mechanical components, musical instruments (such as guitar and
piano), computer programming, robotics, etc... This business has
allowed me to learn quite a bit about how to run a smooth,
profitable, honest operation. I look forward to the future
challenges and rewards this business brings me. |
