Description
Product Description:
Welcome to the world of the Fulltone OCD Obsessive Compulsive Drive, a pedal that has become the go-to for guitarists across the globe. This modern classic overdrive pedal has been revamped for optimal performance and fidelity. Since its inception in 2004, it has been a favorite amongst music creators and has recently been refreshed with a redesigned output buffer for sonic excellence and a Class A input section for an enhanced dynamic response.
The updated output buffer ensures that your tone remains consistent, regardless of where in your chain or loop switcher the OCD is placed. It also minimizes loading on the pedal's hard-clipping stage, resulting in more sustain.
The OCD is also equipped with a Class A discrete 2N5457 JFET input section, increasing the input impedance from the previous 330K to 1 mega ohm. This permits better interaction with your guitar's pickups and a noticeably enhanced dynamic range.
In addition to these exciting updates, the OCD now features switchable Enhanced Bypass or True Bypass modes. Fulltone has developed their own version of bypass called Enhanced Bypass, delivering a more expressive sound than you can get from traditional buffer circuits. The OCD v2 also offers True Bypass mode accessible via an internal switch.
Key Features:
- Great overdrive tones for electric guitar
- Wide range of available sounds
- Switchable hi- and lo-peak gain settings
- Redesigned output buffer that resists loading caused by pedals further in your chain
- Updated Class A-configured JFET input section with higher input impedance for better dynamic response
- Switchable Enhanced Bypass or True Bypass switching modes, with no pops or clicks in either mode

Iconic for a reason
“Everyone” knows this pedal or has heard it at some point. It works extremely well on both guitar and bass and gives you perfectly gritty driven tones, even from the cleanest of clean amps.
While it’s not on my board, I always record with it at some point. It’s a great pedal to have in the toolbox.
The Only Pedal I Refuse To Sell
The circuit in this bad boy is completely unique. The output is dependent upon the input, allowing for an overdrive effect that is extremely responsive to the player's attack. With both a high peak and a low peak setting, your tonal options range from a subtle, bluesy tube OD to full-on screaming fuzz. I have like three of these on my board. The OCD is incomparable and irreplaceable.

Great Overdrive Pedal, Not What I Was Expecting
Let me start off by saying that this is an amazing overdrive pedal. It sounds great, is very versatile, and isn't terribly expensive. However, I was looking to use this pedal in a more hard rock aspect and it let me down in that way. As you crank the drive, the tone gets lost and it starts to sound very mid heavy and a little robotic. On the lower drive levels it sounds great, but it's just not exactly what I wanted.
141
My Favourite Overdrive
This pedal has a massive amount of volume boost. It works great as a kick to your amp's front end, but it's even better as a foundation overdrive on a clean or slightly hairy amp; then, kick IT with another drive pedal for sonic distruction.

One of the Best
The OCD has that magically something. It's generic enough to work with any genre, but special enough to turn heads while doing it.
I use it with the drive almost full off as an overdrive into a Vox AC15. It brings you over the top without a disconnect between your clean and dirty sounds. It highlights the sounds already there. It goes to full mental when you turn the drive up.
If I could have only one pedal it would be a Tumnus, but I would be wishing I picked the OCD much of the time.

WOW
Well I was using a VOX ICE 9 overdrive pedal for about 4 years of my guitar playing life and managed to not hear that it sounded a little weird at times. It was always missing something tone wise and sounded sort of empty. This OCD replaced it quite well. It can be a simple crunch clean boost or it can be a loud and heavy sounding distortion. Has moderate sustain and excellent tone. Well reputable and a classic pedal. What's not to like!?

great, affordable overdrive pedal
I use this while playing live at almost every show when it is too small of a venue to crank my deluxe to get tube overdrive and this thing sure does deliver. A cool trick i've been doing recently when using this with a my Peavey Vypr SS amp in order to get a great sounding feedback is to turn this pedal on in unison with another overdrive/distortion pedal that has been dimed and then point your guitar's pickups at your pedalboard. I personally use a ProCo rat for this

Man I love to have one of these

Killer overdrive
This my mainstay overdrive pedal and I love it, I never leave home without it.

Not the craziest thing in the world, but sound good with other distortion
OCD has a pretty dark tone, and not much grit, so maybe not for guys who like their distortion with some gritty high-end. I'm usually up in the previously mentioned statistic, but I am lucky enough to have a Pro-Co Rat, and together those two pedals can get you the nicest damn rock tone there is: the rat boosting the OCD gets your a really punchy low end, ex. for Josh Homme type tones, while vice versa you can get amazing heavy sustain and a good mix of bass and treble, good for a Smashing Pumpkins kind of sound. Overall, it's a great overdrive for those who don't want anything insane, and for those who do, it sounds astonishing with that crazy distortion pedal that can never give you enough low end. Works for me, hope it works for you.

Great Overdrive
The OCD reacts so well to your picking, a soft attack yields a wonderful clean sound, then go a bit harder and the dirty comes in. Also keeps your guitar sound like it should, you're playing a Strat, it sounds like a Strat, a Les Paul, it's a Les Paul.

its actually a very refined voodoo lab overdrive, not the sparkle drive, but the odler overdrive that's discontinued. That circuit is basically a Rat with a very important difference, the back to back clipping diodes don't shunt to ground, they shunt to the 1st opamp stage's bias potential making the clipping threshold variable based on your playing... fuller stole this great idea and refined the tone control, voicing and switched the stock diodes 2 diode-wired mosfets with an extra germanium diode on one side (ala boss' DS1) to wring maximum amplike response from an already good circuit. Which is why eh makes the big bucks even though he never invents anything himself.

Thanks for the Jimmarchi1 - good to know the story behind the pedal.
