The Envelope Filter is one of the most enduring pedals from this era of DOD, simply due to its wide availability. Envelope filter and auto-wah on guitar is an effect that is niche by design. 

Most players who use filter effects tend to stick to the expressive capabilities of the wah pedal. That said, there’s always the odd player who prefers the more synth-like, locked-in sweep of an envelope filter.
