The Electro-Harmonix Deluxe Memory Man (EH7850C) is one of the most iconic, highly sought-after, and legendary vintage analog delay pedals ever produced. First introduced in the late 1970s, the EH7850 and EH7850C circuit boards represent the coveted "Big Box" 5-knob chassis iteration that established the industry gold standard for warm, musical ambient echoes. The magic of the EH7850C circuit relies on genuine Panasonic MN3005 Bucket Brigade Device (BBD) analog chips. Two MN3005 ICs: The board features two of these rare chips working in tandem to deliver up to 550ms of pure analog delay.Sonic Profile: Unlike sterile digital delays, the repeats on an MN3005 circuit decay gracefully, getting warmer, darker, and slightly lo-fi with each repeat.

Blending in a subtle touch of chorus mimics a vintage tape echo, while moving to vibrato creates a distinct, warbling, multi-dimensional shimmer.Dual Outputs: Features an Effect Out (mixed signal) and a Direct Out (dry signal) for classic stereo-widening amp configurations
