BOSS的好一些~~声音没那么“电子”，DIGITECH的声音普遍失真比较温暖。就算是2101好不到哪里去，而且如果你去DIGITECH的网站看看他的音色下载的话，大部分的音色都是用GRUNGE做的，这就说明了DIGITECH的失真源并不是很丰富，而BOSS的要好的多~~~而且BOSS的GT-3、GT-5还有即将出来的GT-6等都带有“SEND和RETURN”，你可以自己串一个失真作为失真源用（当然也可以用做别的方面），注意：这种串的的方法是可以调节你的单块的位置的，它可以在压缩后；而DIGITECH的大部分效果器都没这个“SEND和RETURN”，2101有没有我忘了~~。
还有就是BOSS的和块的踏板比DIGITECH的好一些~~~~以上是一些我的个人意见，仅供参考~~~其实有一篇BOSS GT-3的英文介绍，里面有它和DIGITECH、LINE6、J-STATION的其他品牌的效果器的比较，看一看就知道了~~……等等我找一找：
啊！！！找到了：
Q: How does GT3 Compare against POD?
A: The POD has better modeling, with more types of amps modeled. The GT-3 has more and better effects. Also, the POD would require an external pedalboard for live use.
Q: How does GT3 Compare against RP-7?
A: The RP-7 has a better fuzz and flanger. The GT-3, in general, has more effects, better effects, and more parameters per effect. In addition, the GT-3 has more patches, an extra button for control pedal, external overdrive/effect loop, MIDI, multiple assignments of control and expression pedal, better cabinet simulations, and BPM function to synchronize tempo of effects to that of the song.
A number of RP-7 users will argue that the distortions sound better because of the tube. It has 4 solid state (Overdrive, Fuzz, Heavy Sustained, Grunge) and 4 tube (Clean1, Clean2, Blues, Saturation) preamp voicings. On the Digitech web page, there is a library posted of user patches. There you will find that most of the patches posted use the Grunge preamp, which is a solid state preamp.
Q: How does GT3 Compare against RP-14D?
A: The RP-14D is similar to the RP-7, but the preamp and equalization sections have been changed. The RP-14D has more buttons - the top row controls the on/off levels for footswitches, and the bottom row selects patches. There is also a switch under the expression pedal, which allows the user to engage the wah at any time in any patch. Plus there is an amp channel switch which could change your patch from a mellow Blackface simulation to a terrifying Rectified sound. And the Digital output is a feature which the GT-3 does not offer.
Roughly the same types of amp models are offered between the two units, although the GT-3 may offer a few more. In general, the GT-3 has the same advantages over the RP-14D as it has over the RP-7 (see above). If the RP-14D has the same quality of digital effects as the RP-7, than the GT-3 has the advantage in effects. The GT-3 has more patches (200 factory/140 user vs 50 factory/50 user). The RP-14D has 3 band EQ. The GT-3 has 3 band EQ, plus an independent parametric EQ having low, high, and 2 parametric bands with adjustable resonance. The GT-3 has MIDI control, useful for storing patches (or previewing patches without entering in all the parameters), which the RP-14D does not. Also, the GT-3 displays patch names, the RP-14D displays only numbers.
不知道够不够啊~~~~~~~至少当个参考吧~~~~~我信赖BOSS！！！！！！！！！！！！！！！！！！！！！！！！！！！
