Anyone considering this ou the full Helix, don't forget you can install a 15 day trial version of Helix Native on Mac/PC. I've been giving it a go myself and find the following so far:
Overdrives: The legacy ones are mostly lacklustre but the Teemah (Timmy), Compulsive Drive (OCD), and Obsidian (B7K) from the Helix set are all outstanding on bass. Definitely the best digital drive sounds I've heard, I would be happy using these for sure.
Octaver: No classic bass octave down in the standard range but the legacy Bass Octaver is excellent. Doesn't sound anything like an OC-2 but it's fat, sounds great blended with the dry signal, and tracks well with low latency. The simple/dual pitch from the Helix effects offer a decent POG-like effect.
Filters: The Tron Up / Tron Down from the legacy range are pretty good and walk all over the filters from the new FX selection. Still prefer my Fwonkbeta and Discombobulator though!
Phasers: There is a Script Phase 90 on offer, but unfortunately not my two favourites the Block Phase 90 and Small Stone.
Overall, not quite enough there to make me ditch my pedal board just yet!
This was sort of my initial line of thought as well. Not saying you wont change your mind. But I found the more I messed with the HX, the more I heard just how good it can be. Then I thought maybe my ears were just "getting used" to the sound of the pedal. That's when I A/B'ed a lot of stuff on my board with the HX. Kinda blew me away. So as of today, from a week ago when I got it, I wasn't sure if it would go on my board.....I slapped Velcro on it a couple days ago and it will be going on this weekend....
