OCD是大家很熟知的一个效果器了.这里象大家简单介绍下如何鉴定自己手中的版本.到目前为止OCD已经出到了第四版.而你手中是第几版呢? 和其它的版本又有那些不同呢 ?目前为止市面上销售的,每个版本从外观上来看都是一模一样的,不同的只是内部.OCD电路与从最早的版本随着时间的推移已经做过4次的正式修改 .每个版本的声音都是有差异的. 从这里我们可以看出:不是什么东西都是最原始的版本就是绝对的最好! (收藏者与炒作者除外)
当然了,音色的审美不是绝对的.也许别人不喜欢的,你很喜欢.但是从大众的角度来讲,产品的研发者不会把自己的产品越弄越糟.尤其是这样的手工品牌.
首版:Version 1 编号:#000 - #4563

4版:Version 4 编号:from #16061 upward *NOTE
变化:-Added germanium diode in clipping section
-Volume control pot tapering changed (logarithmic)
-Opamp feeback loop capacitor and tone control capacitor values lowered for decreased bass response
声音:-Less bass
-Richer even order harmonic distortion due to to asymmetrical clipping
-Improved Volume-control
Sound differences:
The change from version 1 to version 2 is soundwise rather small. The Volume-control is slightly smoother, but the overall sound is affected very little. The high end is slightly softer and the bass maybe a little bit weaker, but all in all a very subtle change.
Moving on the next version the differences in sound are significantly larger. The amount of distortion and volume is increased, the mids strongly boosted and a slight touch of compression is noticeable, whereas the shiny high end is reduced. The structure of the distortion is slightly smoother and rounder, not quite as gnarly and gritty as in the previous versions. The differences are not radical here either, but definitely very noticeable. Version 4 is again not a dramatic but very noticeable change. The asymmetric clipping creates stronger harmonic content and makes the sound rounder and smoother. Compared to the v3, the v4 has now a higher clipping threshold resulting in a larger voltage swing before clipping occurs - the overall amount of distortion is thus slightly less giving a more transparent sound than the v3.
Summary:
All versions of the OCD are very good, high quality overdrive pedals. Its enormous dynamic range cleary distinguishes this pedal from the mainstream of overdrives and gives it a unique soundscape and flavour. Nevertheless, the large dynamics combined with a very transparent and articulate sound set high requirements on the playing and on the used equipment. Unlike with many other overdrive units, the OCD cannot be used to cover up a bad sound from your guitar or amplifier - on the other hand accidental uneveness in playing intensity will result in variations in the amount of distortion, which might sound strange (- of course this could be alleviated with a compressor in front of the pedal).
Due to its nature the OCD may not be the right choice of overdrive for everyone, although its tone and character are really great. For a beginning comping guitarist seeking for his/her first overdrive pedal, the OCD may be way too dynamic, but for a guitar player, who seeks after great tone and an overdrive that strongly interacts with the playing intensity, this pedal is definitely top of the line.
Version 3 of the OCD is slighty more forgiving in sound and dynamics and it's stronger middle-boost and distortion make it more suitable for comping and riffing, but it lacks some of the crystal clear transparency and articulate character with enormous dynamic range. The asymmetric clipping of the v4 give it a slightly new flavour with richer harmonics compared to the previous version and again increased transparency from v3.
PS:至于那个版本好,那个不好其实谁说了都不算.只有自己说了算,呵呵 !因为你是购买与使用者~~你喜欢那个,那个就好:)
由于时间,今就不具体翻译了.对不住兄弟们了^7
