问个有关WANGS的通道切换问题,希望用过的朋友来解答一下..
wangs vt-15,貌似是不支持脚控的,也就是说俩通道之间要切换的话,只能是靠手动去拔插头了.感觉这样很不方便啊..
所以我在想,如果用个AB盒来充当"脚控"行不行呢?这么做对音箱会不会有损害?谢谢~ 我也这样想过，但是切换过来后也不能直接用，失真通道的调节参数和清音通道的调节参数不一样。 原帖由 西部嫖客 于 2010-9-30 11:29 发表 http://bbs.guitarschina.com/images/common/back.gif

调参数就调吧哎没办法了...我想知道这样做对机器有损害没.. 原帖由 bL4cKw0RLd 于 2010-9-30 13:40 发表 http://bbs.guitarschina.com/images/common/back.gif

我查了一下具有类似设计的JCM800 2203,老外们说,2203是单通道双输入(看来不一定是能清音能过载就叫双通道啊),插其中一个就自动屏蔽另外一个,所以AB盒的做法在2203上是不行的,只能改电路.
不知道VT-15是不是这种设计啊.. If you want to make a 2203 a channel switcher, you will have to mod it. It's a single channel amp with 2 inputs. The low input has 2 gain stages and the high input adds a third.
When you've a cable in both inputs it opens the circuit for the signal in a JCM 800. The high input goes through the first gain stage, through the low input jack, and on to the next stage. The low input drops you in after the first gain stage, hense the lower gain and volume. Having a cable in the low jack opens the signal circuit for the high input.
As the guys have said, you'll have to mod and it's a pretty big mod. Kevin O'Connor has a description and layout in his book The Ultimate Tone Vol. 1.
The OD pedal option is good but it's just not the same as having the amp wide open IMO.

wangs vt-15不能用AB 盒
蛋汤了..那岂不是要抽插了... 是不是搞个booster就能解决问题了
还有加上EQ啥的不知道行么？？？
