Akai Analog Delay模拟延迟效果器评测
http://www.gugutown.com/uploadfile/2012/0807/20120807052303897.jpg这款Analog Delay效果器采用了真实的BBD电路设计，能够达到较长的延迟时间（最大延迟为1.2秒），比其它大部分模拟延迟效果器的延迟时间要长。
音色：
这是一款你所期望的模拟延迟效果器，从最小延迟时间的状态下做到的铿锵有力的混响，到较大延迟时间的打点控制，一切都只需要通过它面板上的旋钮操作即可。

当你踩开它之后，它会进一步的修饰你的音色，如果你用过一些比较普通的模拟延迟的话，你会发现，它的每个延迟重复的音色都比你想象得要明亮一些。那些普通的模拟延迟的声音会比较暗，这样会使你的音色变得浑浊。

总评：
如果你不介意明亮的音色，那么它是一款既价格公道，操作简单又非常实用的模拟延迟效果器。

来自：谷估堂 好东西 这个....和Biyang AD-8有什么关系吗？......
[ 本帖最后由 黑月追风 于 2012-8-10 11:34 编辑 ] 模拟的会到1200毫秒吗？不是说模拟的最多就600毫秒吗？ 单片3x05的延迟时间大约是300ms，如果1200ms就是4片，成本都不菲
我觉得应该是谷估堂搞错了，这个应该是PT2399做的 找到一些信息：

In the comments:
" It´s two digital PT2399 chips, believe me or show me that I´m wrong... Even Biyang themselves? confirmed that, saying that "analog" only means that it sounds analog. I had a AD-8 and I had a look inside. And btw: I´m a pedal builder myself, I know what I´m talking about..."
Edit: And from that thread on GFS you linked!
"The Biyang AD-8 Analog Delay is digital, not analog. Just as AD-10 it uses PT2399 chip and not an analog BBD. The picture shown above is not from AD-8, actualy it is not from delay effect at all. The MN3007 BBD as mentioned is 1024 stage BBD, so to reach 1100ms delay of AD-8 you need like 16 of them, which would be insanity. The MN3007 is used primarly in chorus and flanger pedals, they are rather common and you can find them in Biyang CH-7. The costly ones are MN3005 (4096 stages) and MN3008 (2048 stages). In AD-8 case there are actualy 2 of PT2399, first one gives 600ms while the second is engaged for 1100ms mode, hence effect is marked as dual chip."
