As a bass player for over 20 years, I 've grown lazy over the years since bass equipment tend to weigh a lot. Imagine the feeling when a buddy of mine recommended this preamp and all of a sudden I had a really nice sound at all times, and it fit in the gigbag to boot!
The BDDI has a really nice standard tone and with a little tweaking you can get it to growl nicely as well. The one thing I missed the most was the lack of mid control. You get to cut / boost bass, treble and gain, but that's pretty much all.
Still, it sure beats dragging around heavy amps and cabs to every gig. :)
