Wireless Distorting with High Output Basses

[King Tut]

Ive used four different wireless systems over the years and they've all seemed to suffer from some distortion (not the nice kind) particularly when digging in with high output basses. I was gigging last night with a passive jazz (quarter pounder pups) and even with that I noticed it a couple of times when playing hard over the bridge pickup.

 

I'm wondering if this a 'thing' with wireless systems that we just have to live with or whether it's just the systems that I've used and need to splash out a bit of dosh on something better. So far I've used a Senheiser Freeport, Line6 G30, Xvive and currently on Lekato WS50.

 

I'd be interested to hear your opinions and learn from your experience. Cheers.
