The GFX 25 Extreme Envelope Filter is a rare variant of the FX 25b, which was an upgrade to the FX 25 with the addition of a blend control. It was derived from DOD's well-received 440 Envelope Filter, and like the 440, the GFX 25 uses a bandpass filter circuit where the peak frequency is determined by the input signal level, for a touch-controlled wah or auto-wah effect. However unlike the 440 the FX 25 has lots of low end with a huge resonant filter. Its a nice funky and groovy pedal. It has a really nice growl in certain settings, and is the go to pedal on bass for the reggae dub / Bill Laswell low pass tone. It is "Used". Shipped with USPS Priority Mail.
