Ambient, I don't...
I'm currently running a Line6 POD xt Live (guitar version) with the Bass Expansion pack, and I'm very happy with it. I previously had a Zoom B3, which was great, but not flexible enough. Prior to having that, I used my very old, but very trusty Line6 POD xt (red kidney bean version) for years without the Bass expansion pack for both bass and guitar.
BigRedX, totally agree with trying tech from 5 even 10 years ago. The POD xt Live being case and point, bought it second hand, totaly meets my needs, and well worth the money. My good old kidney bean POD xt is now 13 years old, and still going strong.
