A rare variation of the FX 25b, which added a blend function, the GFX-25 is derived from the classic DOD 440 Envelope Filter. The bandpass filter circuit determines peak frequency from the input signal level giving you a touch controlled auto-wah effect. Lots of low end via the huge resonant filter. Funky, but with a bit of available growl!
