Hey all....
Thanks for the input. I'm checking out the Zoom Bass 2.1A (I think that's what it's called). I like having the expression pedal. I also play some guitar so I just was checking out the Digitech GNX4. It was a bunch of guitar amp models on it PLUS 11 bass amp models. All the effects can be used with both, it has an 8 track recorder built in. It has a USB connecter so you can connect it to your computer and many other options I don't want to take the time to list. Check it out at the Digitech website.
For playing both and songwriting, it seems the way to go. You can lay your tracks down.. export it to your computer and burn it to a disk, then take it to church and have the band check it out. OR just take the unit and play it from the flash memory. It looks like it's the way to go...
