j'ai une vieille electric mistress de77, et je la trouve vraiment excellente.
Par contre, j'ai entendu dire que le hoax (qui fait aussi phaser si j'ai bien compris etait tres tres bruyante. Et quasi inutilisable a cause du souffle sur certains reglages... Et que le souffle et autres buzz étaient le seul (mais enorme) défaut de cette pédale...

"Unfortunately, there is also one serious problem: the FH is very, very noisy. Electro-Harmonix' early delay-based devices were infamously noisy, and the FH preserves and possibly even advances that tradition, although it doesn't sound anything like vintage E-H pedals like the Mistresses or the Poly Flange.
When the Blend control is set to full-wet, where most of the interesting TZF and sound-warpage effects are found, the FH emits a wall of hiss that even an external noise gate is hard pressed to disguise.
Of course, full-wet is the worst case for a BBD-based device, but the FH is bad even by "BBD standards." Sweeping the delays, either manually or with the Modulator, shows that the amount of hiss is dependent on the delay time, and worst at short delays.
Oddly enough, other typical "BBD problems," such as distortion and clock whine, are less obvious than in many analog delay effects, and the FH generally avoids the pitfalls inherent in a TZF design, such as sonic garbage due to intermodulation products from two different clock frequencies."
