Can you say why in public? I'm a fan of free exchange of info so everyone can benefit.
Yeah, I've said it before but its the same issues as for almost all other 'bass' multi fx.
Generally speaking the manufacturers are just reusing DSP chips from existing guitar fx with some tweaked settings (EQ points for instance).
Trouble with this is bass needs different fx to have the most DSP power since different fx are more relevant to bass. Also the order of the FX is an issue with almost all Bass FX.
In the case of the BP8 it essentially does this chain:-
Comp -> Preamp (distortions etc) -> EQ -> Expression Pedal -> Modulation -> Delay/Reverb -> Master level
Which looks fine EXCEPT, modulation includes the envelope filter, so add any compression and/or overdrive and you negate that effect's abilities alot. Reverb is fairly useless for bass, as is delay - not always but usually. Yet we can have one of a chorus or phaser or flanger or env filter AND a reverb or delay. We CANT have env filter and phaser, or chorus and env filter. Which shows that this is really a guitar FX unit, since both the above are very reasonable wishes for a bassist. We cant distort the output from an env filter either, neither can we compress the output from an envelope filter after the env section, which is what you want to do. But we can put a reverb on any of the above - which you just wouldnt do _normally_.
It really really gets up my nose that no one really makes a multi fx unit for bass designed to properly meet the needs of a bassist.
The BP8 is good, it has a really really good compressor, a tube preamp, a usable (with some fiddling) env filter, a really cool tremelo (u can get some groovy B3/leslie chords out of it!), and its very quiet, but it could have been phenominal if they got the processing order right and the correct strategy around what bassists need to use together.
