text: However, the Swiss flagship of international heavy rock needed time out.Fernando and Marc had endured 8 years of constant writing, recording and touring with hardly any time off. Coming dangerously close to a burn-out they went on hiatus at the end of 1988. Von Rohr, Kohler and Crivelli tried to continue with Swedish vocalist Björn Lodin (from the bands Baltimoore and Six Feet Under) and lead guitarist Many Maurer, Crivelli's former bandmate from Killer. That line-up was short lived and never recorded any material. Later years (1989–2006)
  Guitarist Fernando von Arb would remain the sole constant member throughout most of the 1990s as Krokus carried on with ever-changing line-ups. 1990's Stampede featured von Arb, former Headhunter members Peter Tanner (ex-Bloody Six, Witchcraft) and Many Maurer (ex-Killer), drummer Peter Haas (ex-Calhoun Conquer), and bassist Tony Castell. 1995 saw a brief reunion of the classic One Vice at a Time line-up, minus von Rohr, on the To Rock or Not to Be album. Welsh vocalist Carl Sentance (ex-Persian Risk, Geezer Butler Band) joined the band for Round 13, with Haas returning on drums.
