A great find that solved a lot of issues for me

This pedal rules. To me, the sound sits right between a TS-9 and an SD-1, although I believe that, circuit-wise, it's closer to the SD-1. It can do light-and-soft like the TS-9 but has more gain and grit available. It matches the SD-1 in crunch but has more clarity and gain range, especially in MOSFET mode. It is quieter than both pedals. It feels like a higher-quality blend of both pedals. The FM/Vintage option really helps in pairing this pedal to different amps. I'm currently using Vintage with the MOSFET setting but have nailed some great sounds in other settings (I have not yet made peace with the Comp Cut setting). The ONLY thing I wish it had is a silent switch. I have to turn it on during a quiet part in our set, and that click drives me bonkers.

Workhorse Overdrive

I've had my Full Drive 2 Mosfet for about 8 years now. It's been a constant tone in my arsenal for about that long as well. Not only is it durable, but it offers quite a bit for diversity of tones with the switches that are on board - making it the perfect overdrive pedal for a number of different settings/genres.

Full disclosure - I'm looking to sell mine. But not because of dissatisfaction, just ready for some new gear and need the $$ to finance that endeavor. It's been a terrific 8 years with this on my board. Would still recommend it to anyone looking for an overdrive that gives you some great options all in one pedal.

From clean, passing by boost up to overdrive.

Nice and humble pedal, with a lot of features. The sound feels not at all transparent, as it has added a little compression and probably the original signal is added in parallel with the effect to produce this pedal sound, which is really good. If you listen to Kings of Leon, you definitely want this pedal to achieve their sounds.

Using the Blues Driver and the TS Mini in parallel with the Boss LS-2, I can get many sounds from the Fulltone Fulldrive 2 Mosfet.

I bought this one after I tested a friend's FD2 with the Vox AC15C1 and finally getting all those sounds from the 'Because of the Times' album from Kings of Leon in 2007.

Probably I'll get rid of my other drives, but not by the moment. I've used the Blues Driver as clean boost before the Fulldrive 2 obtaining good sounds.

The EP Booster pushes well the Fulldrive 2 pedal, as this has headroom just when is pushed with the internal boost in the pedal.

Finally!

I've been looking for a decent drive to replace my TS9 for so dang long, and this finally did it. The Full-Drive 2 Mosfet is extremely versatile and covers all of light OD to crunchy tones, while not burying me in the mix. Bless Fulltone for this pedal.

Favorite Pedal

Certain drives are really hard to dial in with certain amps, but this pedal sounds brilliant with any set up. The drive by itself sounds great, and the boost rivals the tone of a Tube Screamer. It's two pedals for the price of one, and the versatility allows you to go from clean boosts to heavy crunch with one tap. Great pedal.

Nice!

This pedal combines classic rock with pop rock, like I've never heard before. This overdrive made me change the kind of music that I write. It's easy to control and still has a lot of nice features!

Very Clean Dirt!

For a little over a hundred bucks you get a hand-built in the USA, two-channel overdrive pedal, that has many gain and OD variant options. It's built with high-end components, including some Fulltone proprietary parts, like their own 3PDT switches and custom made copper wire. It's probably one of the cleanest, best built dirt pedals on my board—and it's the least expensive pedal I own. ;)

Great sounding unit with very solid construction

Vintage and standard settings gives the usual TS tone, which off course sounds nice though I don't care much about it as I prefer the flat midrange and MOSFET settings to achieve a punchier response with more balanced tone and dynamics. I like how the boost switch is implemented as it just kicks in more gain. I always use guitars with HH mic configurations, then even at bridge positions with no treble cut and with my MF Boost at the maximum of its tone knob the FD's tone knob range does never become much sharp nor super bright. All this considering that I always feed it with 9V and run it at home through my Vox AC4C1 and at rehearsals and concerts through my Vox AC30CC2.

A tweakable TS808 clone with essential boost switch

A very tweakable TS808 clone. It pushes my AC15 nicely. It stays transparent and the boost switch is essential.

Great blues/rock sound with a TS like taste

Very useful pedal. I combine it with OCD to achieve a gorgeous sound to lead guitar solo. It's nice to chord word and strumming, with low gain for me. I use it on FM and Mosfet to clearer sound than vintage. As a clean boost i heard good comments but i don't use it at all. Well, we know that itá a classic pedal!
