Vortex Sound Research

Hi, I have a Model:Samples that I use sometimes as a normal drum machine, sometimes as an instrument on its own. One thing I really like about this unit, is cranking the delay feedback up beyond self oscillation and start playing with filters and stuff. It sounds amazing, but it is also really dangerous for both my sound system and my hearing abilities, imagine doing this on stage. So I was thinking about a limiter or compressor pedal or something like that to keep the volume levels safe.

Do you know any cheap unit (no more than 100€, I'm in Europe btw) that can do this work? Something I can bring to a gig, not a rack unit. Thanks
