How many of you use a second amp just for your looping/DL-4?

[wyattt]

I have a DL-4 and I run it through a Metro Amp JTM-45 combo, but with the indie/punk stuff I do, I'm thinking I may want to get a second amp to run my loops through. I am into loops ala Minus The Bear (tapping, etc..) or ambience ala Explosions in the Sky, Appleseed Cast, Mogwai, etc..

So how many of you opted for a second amp vs. running your loops into the amp you are going to be playing additional parts through?

What are you using? I'm considering a DRRI, or a AC30, or maybe a Vibrolux Custom RI.

Do you also send some of your pedals (via stereo or other routes) to that amp or leave it with just the DL-4 in the signal path?
