The Acetone F.A.T. Dual Drive is a dual-channel overdrive pedal from Acetone, covering both overdrive and distortion. RockBoard's PedalPedia describes it as delivering "the rich, midrange-focused drive tones that defined classic rock", with a sound of "smooth, compressed overdrive with a warm, vocal quality that sits perfectly in any mix" that cleans up with the guitar's volume knob1. It sits among overdrive pedals and distortion pedals that use two gain stages in one box.
Two channels, one pedal
The pedal puts two independent gain stages at your command, each with its own footswitch and channel. Each channel features independent Drive and Volume controls, so you can set the gain level and output level of each stage separately1.
The two channels are not limited to use one at a time. The maker describes configuring them for different gain stages or stacking them together for "massive, layered overdrive", and a Pedal of the Day review of the related RayGun FX Dual Fat Drive likewise lists the pedal as having "2 Channels" that can be combined12.
Internal clipping switches
Beyond the front-panel controls, internal switches on each channel offer additional clipping options. These let you customize the pedal's voice from open and dynamic to more compressed and saturated, so each channel can be voiced differently depending on whether you want an open, touch-sensitive low-gain stage or a thicker, more saturated lead sound1.
Power
The F.A.T. Dual Drive runs on 9V DC, center negative, the standard supply format for compact pedals1.
The product page gives the voltage and polarity but no current draw figure, so check your power supply's per-output current headroom as usual when adding it to a board.
Questions
Is the Acetone F.A.T. Dual Drive analog?
Yes. The F.A.T. Dual Drive is an analog circuit, listed with a circuit type of analog on its product page. That matters for players who prefer the way analog overdrive and distortion respond to picking dynamics and the guitar's volume control, which is a trait the pedal is described as having: it cleans up as you back off the guitar's volume knob.
What power supply does the Acetone F.A.T. Dual Drive need?
The pedal runs on 9V DC with a center negative plug, the same standard supply used by most compact pedals. No battery option or current draw figure is given on the product page, so a standard isolated 9V DC center negative output from a pedalboard power supply is what to use.
Can you run both channels of the F.A.T. Dual Drive at once?
Yes. The pedal has two independent channels that can be combined. The maker describes configuring them for different gain stages or stacking them together for layered overdrive, and a Pedal of the Day review also lists the pedal as having two channels that can be used together.
Does the F.A.T. Dual Drive clean up with the guitar's volume knob?
Yes. The maker describes the pedal's sound as smooth, compressed overdrive with a warm, vocal quality, and notes that it cleans up with the guitar's volume knob. That makes it usable as a always-on drive that rolls back to a cleaner tone from the guitar.
What do the internal switches on the F.A.T. Dual Drive do?
Each channel has internal switches that offer additional clipping options. They let you customize the pedal's voice from open and dynamic to more compressed and saturated, so the two channels can be voiced differently beyond what the front-panel Drive and Volume controls set.
