Fulltone Fulldrive 3 FD3
N.O.S. JRC4558D chip.
Fulltone-exclusive “Order switch” which places the Boost channel either before or after the Overdrive section of the circuit: After takes whatever sound you have set and increases the Volume so you pop out of the mix. Before pounds the input of the Overdrive channel and increases the distortion, there's not a substantial increase in volume...which is more like the FD2.
Three switchable Clipping Modes
"90's" original 90's warm FD2-like voicing. Transparent? NOT! Think Mids, rich Mids, Color, beautiful color. You want transparent? You got the wrong mode.
"Wide Asym"...that's Wide Asymmetrical, for a beautiful, chimey, more open sound.
even more asymmetrical than the FD2,
“Comp-Cut” mode: This mode removes all diode clipping from the JRC4558 opamp, giving it a somewhat clean-boost feature or an aggressive opamp clipping sound on higher “Overdrive” settings. Identical to the FD2.
Completely independent, discrete JFET Clean Boost channel that can be used by itself! This channel has its own Volume control and a unique mini-knob controlling Germanium Diode "Limiter" function that has to be felt to be really appreciated! Clockwise on this knob takes out the strident, irritating spikes that occur with other clean boosts when you hit the strings hard....absolutely gorgeous feature destined to be a classic. This Boost circuit does not invert the signal like most clean-boosts and can be used with or without the overdrive section of the pedal.
The Icing on the cake? The housing is about 20% smaller than the traditional Fulldrive2
