Electro-Harmonix Deluxe Electric Mistress
Electro-Harmonix · pedal
The Electro-Harmonix Deluxe Electric Mistress is the classic analog flanger that defined David Gilmour tones between 1977 and 1983 and remained a pedalboard staple for decades. It ranges from subtle, tape-ish flanging to extreme rotary-style swirl, with a slightly jet-like voice carrying a hint more midrange and low end, and the Deluxe version adds a noise filter for quieter operation than the original. Its Range control sets the modulation width by lowering the frequency range while keeping the upper frequencies consistent, which gives the effect its distinctive treble shimmer and bite, while the Filter Matrix switch freezes the LFO mid-sweep to hold the flanging cancellations in place for unusual, tunable metallic tones. Famous for shimmery, ethereal sweeps, it suits classic rock, psychedelic, post-punk, and ambient players, though it is known for a noticeable volume drop that often needs a gain leveler.

Trade-offs
“The common caveats are a well-known volume drop when engaged that often requires a gain leveler in the chain, and a strong, characterful voicing that is more a featured effect than a subtle background modulation”
