Bass Instruments Similar To Amped And E?

Hi all. I’ve discovered an interesting technique that lets me convert the Bass Amped instrument bundled with Renoise to this:

The technique also works well with bassE and bass303.

I’m looking for similar bass samples/instruments to bassAmped and bassE so I can test out this technique further in the future. Apparently how good it sounds has something to do with how complicated the bass sample is and the sample having a loop at the end. I’ve already gone through all preloaded bass instruments (only bassE, bass303 and bassAmped qualify) and the ones from the renoise backstage pack (the samples are too simple, so nothing came of them). Any help would be useful.
