OCD V2 er designet for å etterligne den klassiske rock gitar tonen som opprinnelig kommer fra en rør-forsterker som koker. Denne forvrengningen er nesten umulig å gjengi i en liten pedal, men Fulltone har kommet imponerende nær, og OCD høres ikke ut som noen annen pedal.
OCD har kommet med mange små oppdateringer de siste 12 årene ofte feilaktig kalt for versjon 1-2-3 osv. I virkeligheten har det bare vært versjon 1 ute på markedet med veldig små forskjeller (V1.1 til V1.7). Juni 2017 kom Fulltone en helt ny OCD V2.
Hva er forkjellig?
Den har fått Output buffer, slik at gitarlyden din holder samme nivå uansett hvor du plasserer den i dagens komplekse signalkjede og du får mer sustain av både lyden og overtoner. Les tekst fra Fulltone under hvis du lurer på hvorfor du vil ha buffer i signalkjeden din.
Class A configured discrete 2N5457 JFET input section, øker input impedancen til 1mega ohms, (tidligere 330k) og øker dynamikken i lyden som resulterer i at pedalen fungerer mye bedre med både singelcoil og humbucker mikrofoner.
Intern switch knapp for å velge mellom ”Enhanced Bypass TM” & True-Bypass, ingen andre firmaer tilbyr EB siden Fulltone faktisk oppfant dette.
Dette er en pedal som maaange gitarister burde ha på pedalbrettet sitt! kom innom og test en i butikkene våres, eller trykk på linken og bestill en i nettbutikken vår, selvfølgelig med gratis frakt.
A downside to True-Bypass:
True-Bypass (TB) switching was the ultimate way to achieve a clean
signal path for many years. Everything’s different now, most guitarists
have elaborate pedalboards with 10 or more pedals being the norm, and
tremendous potential for signal and tone loss with the many cables,
connectors, and other pedals involved in the chain. There can be so much
signal loss that it sounds nothing like the sound of a guitar with a
cable straight into the front of a great tube amp. Uninspiring.
What’s the pedal industries’ solution to this problem for the last 40 years?
Unity-gain buffered bypass…i.e. a couple of Field effect Transistors
(FETs) configured as unity-gain buffers ala Boss, Ibanez, etc, etc.
What’s the benefit to unity-gain FET buffered bypass?
It reduces the loading effect that occurs using long lengths of cable,
and you remove the loud “popping” sound when switching the device on and
What’s the issue with unity-gain FET buffered bypass?
Although my ears always told me that it sounded “tinny” and that there
was signal loss, with the help of a my favorite Electronic Engineer
(using some very expensive test equipment) we recently documented that
each unity-gain FET buffer actually cuts the gain somewhere between 0.3 to 0.6 dB.
This loss of gain is in the low-Mids and Bass frequencies, resulting in
that “tinny” sound now that the highs remained and some of the bass and
mids are gone. Now factor in that there are two FETs per pedal required
to couple the IN & OUT path, that’s an obvious loss of between
1dB-2dB per pedal.
What’s an even bigger issue with this old style unity-gain FET bypass?
It kills dynamic pick response, i.e. it kills the
difference between picking soft and picking hard…Yes, when the pedal is
in bypass! This to me is a deal-breaker, and while I’ve always felt this
to be the case, it’s great to be able to actually see it on the scope.
What’s the solution?
Enhanced Bypass! Configuring both of the switching FET’s Class-A!
By configuring a FET for gain (also referred to as wiring it “Class-A“) all the dynamics return (and then some), even if you only configure it with the slightest amount of gain, in this case: 0.3 to .06 dB.
People rave about old EP-3 Echoplexes and Ep-3 type boosters, and
although they know that they love what it does to the guitar’s sound,
they can’t explain why. It’s because of the Class-A FET preamp! With a
Class A FET the dynamics get amplified, allowing an even greater range
of expression than if you were playing through a guitar and just one
cable straight into your amp. The downside with EP-3 preamps is that
they throw the signal OUT-of-phase, boost treble, and cut bass. Fulltone’s EB the signal exits the pedal IN-phase and doesn’t change the EQ at all.
With OCD V2’s Enhanced Bypass you get this benefit whether the pedal is turned ON or OFF.
This means that just having the OCD turned off in your signal chain
makes the whole rig sound alive, fresh, and more powerful again.
