I've just read through this thread and it's been interesting hearing the experiences of others. I really like my BFR,, the simple compression and chorus controls work really well for me and the Sansamp section sounds great.
However, I've not been able to get much from the Octafilter section.. Has anyone has had success with this? I'm trying to get a decent envelope filter effect out of it, the demo's on YouTube from Tech21 sound great but, I can't get the same intensity from mine. I have to really dig in and even then the effect reminds reasonably subtle, especially with the range dial at 9 o clock or above.
