Electro Harmonix Small Stone EH4800 Phase Shifter USA Version 4
Here we have the fourth USA version of the Small Stone which was produced in the mid 90's (first USA reissue) and was the first USA version to have a status led, a very useful addition to make life easier for the gigging musician. A 3PDT (Triple Pole Double Throw) foot-switch is used to implement true-bypass switching. Again the circuitry and the board layout have been modified heavily from the previous versions, but it is still based on 5 CA3094AE single chip OTAs.
The Small Stone has earned its status as one of the most influential phasers in the history of music, and throughout its long existence it certainly has made itself known to most musicians. The unique flavor in the sound of the OTA based phase shifter is distinguishable in all the different versions of the Small Stone, although they all have slight differences.
