Citation with bib latex

I am using biblatex:

usepackage[style=authoryear-comp,maxnames=1,uniquelist=false]{biblatex}

when I write

for a detailed version see cite{bernd1}

then I get

for a detailed version see Bernhard Spald 1990.

but I would like to have the following:

for a detailed version see [Spald 1990]

I don’t know how to do it with biblatex? I don’t find the right citing style…

Thank you in advance
