I've been looking for a FRFR powered speaker for the Helix that sounds better than the Headrush 1x12 I've been using. Came across this one used in practically new condition. 500w 1x12 and built to withstand a nuclear assault. Only downside is it's a little large and damn heavy. Weighs in over 60 lbs I believe. But most importantly, it sounds phenomenal. This is the cab version. There's also a wedge monitor version which may have a smaller footprint. What it lacks in portability it more than makes up for with its sound. If you're into modeling pedals and have felt like your FRFR has been missing something, I highly recommend checking one out.
