I have a Zoom B2.1u. For me it's perfect! For a better analysis, check my recordings.
For recording, I used the Zoom multieffect via USB direct to my notebook. The software is the CUBASE (come with the product).
Basses used:
Squier Jazz Bass V Deluxe Edition
Condor BC-600 Fretless.
Songs recorded:
Space Truckin' do Deep Puple (pick- Squier passiv)
Ink Illusion do Alain Caron (Fingerstyle - Condor Fretless)
Power do Marcus Miller (Slap - Squier active)
