Hoping this will be educational. I'm trying to categorize delay pedals; expertise is sought to educate TGPers everywhere! I'm doing this from a voicing/tonality standpoint rather than a features bent (tap tempo, max delay time) So... Delay/echo pedals fall into the following voice/tone categories (with examples): Analog Tape Echo (all are out of production?) WEM/Watkins Copicat (I know the Verve's Nick McCabe used one of these but have not ID'd a track) Tube Tape Echo Fulltone TTE Echoplex (out of production) Metal Disc Echo (same principle as tape echo) Binson Echorec (a favorite of Gilmour in early Pink Floyd...this unit mechanically used metal media instead of poly tape) Space Echo (or Multi-Tap...still tape-based) Roland Space Echo RE-301 (out of production) Analog (strictly circuit-based = sans tape) Diamond Memory Lane Retro-Sonic Analog Delay Electro Harmonix Deluxe Memory Man Maxon AD-999 Maxon AD-900 Toneczar Echoczar Homebrew Electronics Mimic Mock II MGMusic "That's Echo Folks" Malekko Echo Boss DM-2 (out of production) Boss DM-3 (out of production) Analogman AR20DL-XL (600ms max delay time) Analogman AR20DL (300ms) Ibanez AD-80 Ibanez AD-9 Digital but designed to be at least mostly Analog voiced Blackbox Quicksilver? Pigtronics Echolution T-Rex Replica Goudiefx Delay Dr. Scientist Sunny Day Delay Hughes & Kettner Replex (no tape but actually uses a 12AX7) ThunderTweak Delay Freakshow Digilog CMATMODS Deeelay Carl Martin Delayla XL (there is certainly some question about a both wet and dry analog signal) Digital but with at least some respectable Analog voicing within Eventide Timefactor TC Nova Boss DD-20 Line 6 DL4 (Keeley modded) Boss RE-20 Electro Harmonix #1 Echo Ibanez DE7 Digital Guyatone MD-3 Boss DD-3 (Analogman Hi-Cut modded version provides added analog voicing) Boss DD-5 (out of production) Boss DD-6 (Analogman Hi-Cut modded version provides added analog voicing) Monday Morning Growl Delay? The sound I make before getting out of bed on Monday morning. Should a category be added or a description changed? Please correct any mistakes and if you know of famous player references and/or definitive recorded examples, well, you walk on freakin' water in my book- please share with us all!
