they do the same thing...but....It could be that itsbuilt in amp isnt as powerful, Im not sure.Remember I used a differnt amp same size different make it was even more expensive but I went back to original.Roger specially made his talkboxes but If you cant exchange Id stick with what you got cause you aint experience the difficulties of actually emulating certain entertainers that use it but if you doin your own thing like house music it may be perfect. If you trying to make more robot sounds you can run your mic in a cheap harmonizer,that gets some real interesting sounds,are you using a keyboard, and what kind?you can run your keyboard out into a distortion box, or over drive, that adds another bit of grimeyness to it and those lil pedals can be found cheap used, for now Id figure what kind of sound and how to get your key to achieve it( use mono voices only, cause chords dont workits muffled)
Yeah I almost forgot get rid of that big tube that came with it. Go to home depot and get some type of rubber glue, the go to wear they have tubing buy alittle of(about 2 inches, wich you will cut off the ammount you necessarily need)of the size that fits in the part that goes into your talkboxget the next size down and on this one glue a small maybe inch into the first then so on and so one til youhave the desired thickness that will be most comfortable to use,You may have to force the tubes in each other but with that and the glue its airtight, experiment and make different sizes til you get one that works best for you.
Put it in the side of your mouthbiting slightley so it dont come out and just mouth the words( overexaggerating but using no actual sound of your voice just the air that comes from mouthing it.experiment and it aint hard also if using a key board use pitch bend to accent certain syllables and modulation for tremolo, just play around and you will understand more
