The thru would be a big plus for this as that would negate the need for a monitoring feed back from a desk. If you can play at quiet volumes where monitoring is not required and still get the thump, then thats a big thumbs up. Also, would take roundtrip latency out the loop for those guys running wireless systems from their bass with horrendous latency figures. Mentioning no brands and all that.
Woojer is still a big thumbs up. I'm being more sensible with it now - I was running it super strong at first but its defo a more subtle thing as you get used to it... otherwise you feel all beat off once you've finished playing. Funnily enough, I was reading into psycological effects of haptic feedback... and there's unconfirmed evidence that it can lead to panic attacks and paranoia. Who knows?!
