I have it for four days now and really love this one already.
Used it on the drum-bus and smacks it really tasteful on there.
Did seven mixes with it on the mix-bus and for the rock genre songs I tried it out on it works marveously well. It sounds awesome to me, highly recommended for 'that' sound. Freaking great job Behringer !
Three stars for the control because the threshold pots are really a problem, they turn way too tight. I'll be careful with those and hope they last, Behringer definitely needs to solve those but other then that the sound is amazing and that's what counts to me.
If you're hesitating to buy one I would say just get it if you want a 33609 style compressor, this does the job really really well !
I pre-ordered the 1273 as well, I mainly decided it on the transformers which sound really good to my ears.
