I have been using the EDB VAP for two weeks now, playing both large and small venues, and I am honestly thrilled. Both my pickups (Schertler Stat B, Yamahiko) and also my go-to mic sound amazing, the EQ and the tube/valve harmonize great and the routing possibilities are just perfect for my needs - having two separate DI-outs is just perfect and gives me pretty much all the control I want to have before giving my PU and/or microphone signals to FOH. There are quite some good solutions for demanding double bass players and after trying most of them at least for me this is the best sounding solution that still fits in my gig bag. If this thing lasts I have no need to look any further - sound wise I could not be happier with a preamp and yes, I think the VAP is a huge upgrade to its predecessor.
