Description

Edit 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

My low gain drive to "roar"

This one i use to get low gain drive sounds with a roar texture. Sorry, i cannot say to much things despite of its beatiful sound, and dynamic behavior. I just like it too much, but at same time, still looking around for other, to confirm its quality or even chage it some day. I must try j.Rockett Blue Note/Animal and Red Jasper too. I prefered it over Catalinbread DLS MKIII by far.

the other pedals you mentioned are totally different than an OCD. They are more like well-tuned fuzz pedals that produce an OD/distortion sound because of component selection and careful voicing. The OCD is a very well-refined diode-clipping distortion in the mxr distortion+ camp. Its dynamic behavior compared to a 70s design comes from the clipping diodes being connected to the bias point of the op amp that amplifies your signal, so the amount of clipping and behavior of the clipping is really controlled by how hard you pick. Its a great idea, but sadly not Mike Fuller's like he claims. He lifted the clipping scheme from a discontinued Vooodoo Lab overdrive. The Catalinbread DLS (for instance) is based on the General Guitar Gadgets Brown SOund in a Box kit. Nick makes no bones about the source of his awesome design. The DLS uses 2 Jack Oram designed jfet miniboosters as building blocks to simulate that cool odd-order harmonic content churned out by a vintage plexi front marshall. The minibooster uses a pair of small jfets in push-pull to amplify your signal in a non-linear fashion that makes the jfets even ore tubey than they are used singly in class A. Nick at CB did a great job refining the original BSIAB over the years. All of his foundation drives are VERY impressive.

Nice! Cool informations! it's very helpful know about the "inside"and how the circuit works. For a while i feel just the sound and try put on words my sensations. Considering what you said, i won't find a best overdrive pedal to my needs, because is just the "dynamic behavior" of OCD, what i most like on it. Did you try or hear the Red Jasper?

Awesome Pedal. Worth the money.

I was surprised by the beautiful tone of this thing. It's really great for a lot of types of music. I was actually able to stack it with a metal muff and it sounds awesome.

Bit bland?

Saw loads of reviews rate this pedal. I found it to be OK, but nothing that made me go 'Ooh'. Build quality was great but its a bit of a guitar shop pedal. Sounds good on its own, didnt find a good partner drive or boost for this. Got sold.

My best drive pedal!

I love this pedal! I This was my first Fulltone pedal and I've really fallen in love with Fulltone since. This pedal is so versatile and sounds amazing! It's extremely amp like. The LP/HP pedal is what really makes a huge difference. The HP setting really enhances the mids and the LP setting is much more flat.

Best OD Pedal

When paired with my Telecaster, I can't get enough of the sound that comes out of this bad boy. It really is my favorite OD pedal I've ever used.

The bets overdrive available

This is one incredible overdrive as it adapt to the way you play (if you're playing with a hard picking technique you'll have more drive). And it can be use with just a bit of drive. It"s a must have for any guitarist.

Just What I Need

This distortion is a perfectly rounded pedal for almost any use. Whether you want to use it as a solo driver or just to dirty up your tone, this pedal can do it all. Very reliable and easy to figure out. Lots of possibilities. Highly Recommend.

Great pedal for solos.

I don't use it as an overdrive, more as a boost with a "treble boost".

a match made in heaven

this pedal is the perfect OD, at least for my style. I love my Joyo for a light bluesy beachy tone, but when i need a hard OD, especially in a live setting, this is my go to
