Moore's historical archive dates his purchase of the EchoSonic to May 24, 1955 and documents its integrated tape delay. Guitar.com independently reports exclusive use with Elvis from that date through the 1968 Comeback Special, while Premier Guitar confirms that the amp reproduced Sun's studio slapback live. No separate floor effect is documented in this dated core path, so the integrated amplifier echo is described but not misrepresented as a pedal placement.
