Need help!!!

[sometypeofplay]

I've tried both google and searching the threads here and I'm having no luck finding what I'm looking for. So, I'm turning to you the good knowledgable people of TB. I'm looking for a unit/pedal/device for practicing. It seems to me that I've read about such a thing that allows me to isolate bass tracks and change the tempo without changing the pitch. I don't want to get software for the computer unless I have to. I'm looking more for a device. Does such a thing exist? I really need some help.

Look for the Pandora and the Tascam trainer (search here, there were threads about them). Those devices might just fit your needs.

I agree it's sometimes hard to search when you don't know yet what you're searching for ...
