Pedal into solid state amp?

My main amp is a Lone Wolf HarpTrain 10. I like it a lot, but also have an old Roland Cube 30 that puts out a lot of volume. I recently picked up a Lone Wolf Harp Attack pedal, to run int the Cube 30. Haven't played the setup in public yet (still experimenting), but could be doing so soon. So ...

Anyone else here have experience with running pedals like the Harp Attack into solid state amps? What's your experience been? How close to tube sound have you been able to get? How about feedback issues? Other issues or thoughts?

Thanks!
