I use this pedal with my HSS strat and through a blues Jr III and use the clean boost for the coolest clean tone ever.

It gives from a simple clean boost to a creamy smooth overdrive, to a heavily saturated yet articulate overdrive

As a Clean DriveWhen you uses this pedal with less drive as a clean boost for your tube amp, you will notice that it delivers a very strong character from your guitar and is very sensitive to your dynamics while playing

When my Visual Sound Route 66 v1 finally kicked the bucket I needed something that makes up the 3 basic building blocks of my tone (before modulation and delay, etc) compression, clean boost and overdrive

Once I added an Exotic SP compressor with clean boost with this pedal it was looking like I had replaced my beloved old Route 66

Four stars for the pedal itself and two stars for the frustration related to the enhanced bypass garbage that made me pull out more hair from my balding head.

The volume knob lets you correct for all that available drive, and true bypass means you won't lose air and sparkle with your clean tone with this device in your lineup

The OCD has true bypass and enhanced bypass but regardless where the switch is, it wants the true bypass TC chorus before the OCD

The fix: opening it up and switching it to true bypass mode from the factory set enhanced bypass mode.

the buzzing noise was caused by the OCD pedal in enhanced bypass mode?

It's like an extension of your amp (You really need a good solid tube amp to appreciate

It is very clear and boy does it warm up the preamp tubes!

It is Open & Dynamic with Harmonics and Tube Amp-like-feel.

Ideal for powerful rhythm and screaming solos; feel just like one's playing a great vintage tube amplifier

You couldn't get this tone at any price form a solid state emulation five years ago, I don't know what happened, but I like it!

The sound benefit is as hard to describe (but easy to love) - like a tube amp versus solid state - when you hear it

Use it through a small Fender Bronco amp, and my Marshall 100watt solid state amp

I think this pedal sounds really good, even on my solid state amp

The range of usable drive goes from barely-broken-up up to what I consider absolutely screaming, liquidy, sustain-for-ever-y distortion, all available all the time via the guitar's onboard continuously variable overdrive control, AKA The Volume Knob

I also have a TC spark booster and when you set it to 12 o'clock into the OCD, look out for the insane drive it produces

Conclusion: this is a solid drive pedal that does a decent job emulating a broken up tube ampat volumes that won't cause you to go deaf.

A good overdrive, can really crunch, scream, clean drive

It's like an extension of your amp (You really need a good solid tube amp to appreciate

It is the most versatile and authentic amp sounding drive I have ever used

With the Drive knob turned down low and the volume turned up high this pedal drives my amp and boosts the mids like my TS9

I think this pedal sounds really good, even on my solid state amp

then it's the wrong amp

very sensitive and versatile pedal, great price, fast delivery

Hands down, one of my favorite distortions pedals, and one that I use every day, it's completely worth the price for the quality in the sound and construction

Steep price

So many out there, this is a safe bet to start with, good price, built well.

Excellent price here on Amazon, fastest shipping of any supplier

It may not be the most precise way of describing this pedal, but I regard the OCD as a sort of subset of the Fulldrive pedals.

That said, the OCD is still capable of a wide range of distortion/drive effects, and, like all Fulltone products, the build quality is second to none.

The OCD is a more natural breakup than the Voodoo Lab Sparkle

After watching many comparison videos that recommended The OCD i bought it

The twin has the problem of a VERY loud sweet spot, and the OCD has solved my problem of needing to wake my neighbors in order to get there.

Well, now I've bit the bullet after comparing the OCD to the Joyo and found that just like Coca-Cola, "nothing beats the real thing"The pedal gain goes from adding a light, but fat tone and some crunch, to all out, in your face, high gain with the turn of a knob

Can be set to add just a bit of grain and sustain and size to your sound, a difficult tone to get at reasonable volumes.

This is the distortion that gives me that fat tone and that sounds I been looking for!

Love this pedal, sounds great, great tone verity- def one of my favs!

Built solid, great tone, but I hate that I have to remove all four screws to replace the battery

It is much more an "overdrive" in the sense that it keeps the tonal characteristics of your guitar and amp, but boosts the level in gain in a very full, rich sound.

As I read on different forums and viewed on youtube, it yields a warm overdrive that varies with the volume knob and with how hard the guitar is played.

Sometimes I find it hard to strike a balance between low overdrive boost without much sustain or a bit too much harsh overdrive

Even better - this is a GREAT overdrive AND distortion pedal - so responsive to guitar volume and tone settings and picking dynamics

I'm using 18Vdc to supply power, and it deliverys a fat overdrive

Subjective: Nice thing is that it's fairly transparent - there's no changes to the top/bottom end that the tone knob can't fix, and it's fairly good in the transitions area

This thing did the trick

The coolest thing is that this pedal is responsive to your playing dynamics; picking softly dials down the OD, then you can just unleash the crunch with harder attacks...much better than trying to roll-off the volume

But the best thing the OCD does for me is that it makes me feel like a better player

This thing will add bass galore to your sound -- I didn't need any more bass in my JCM900 -- I do use pedals to juice my JCM 900 -- this pedal will get out of rotation pretty soon -- very bassy pedal - not much distortion - very weak -- only thing it is good at is a volume boost -- very bassy -- even when treble is turned up all the way -- if you are looking for a distortion pedal this is not the one -- get a.... dunno anything else and save your money
