Ah, ya can't be too upset...the BDDI has been proven and works for a lot of things. When you say you want a metallic crunch, that's not what most people think of when it comes to good bass tone. As a guy who likes Billy Gould, Paul D'Amour, and tons of post punk/new wave...it's all I think about when it comes to bass tone!
The B3K works for that tone, but don't be fooled - it work for warmer tones as well. I use it all around.
