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 Pedals, email 25/5/2010]

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.
