Guitar Pedal Dating | How To Date a Guitar Pedal

Page Update 3/7/2016


Have you ever wondered if your Guitar Pedal is a vintage pedal?  Some guitar pedals actually increase in value over time and are very collectible.  For example, Some older MXR Script Logo pedals are actually extremely collectible.  Guitar pedals can be dated through a number of websites depending on brand.  But, they can also be approximately dated by pot codes. 

Guitar pedals and some guitars can be dated by their pots.  Most pots (potentiometers) on guitar pedals and guitars subscribe to the Electronic Industry Alliance (EIA).  What is a guitar Pot or Potentiometer?  A pot is basically the component that controls volume and tone on your guitar or guitar pedal.  Therefore the code on the pot can be dated as long as the company producing the part was in the EIA.  The pot codes are usually stamped on the pot.  Make sure the pot is original to the guitar pedal.  Pot codes give you the build date of the pot only not the pedal or guitar.  So guitar pedal dating by pots is basically used to get a roundabout date for your equipment.

Some companies don't have specific guitar pedal dating information on their sites, so try to visit the support section of their website and see if customer support may be able to give you insight on dating their electronics.  It can't hurt to send an email to the company and see what happens.  Visit our guitar pedal manufacturer page for guitar pedal official websites.
