I just got to try the Demeter VTBP-201s for the first time. The power source was a Stewart World 1.6 bridged into a Bergantino HT 322. The basses used were a Warrior Signature 6 with Bartolini electronics and the other was my low rent MIJ Fender Jazz fretless with a J-Retro & Fender Noiseless pickups. The Warrior went first and after hearing it in the mix I wrote the rig off as being a "modern only" type which is not necessarily a bad thing IMO. I was very please to discover that if you put old school in you get old school out of rig such as the one described above. Maybe not Ampeg kind of old school but the Fender definitely put the vintage vibe into action when it was plugged into the same rig. That combination had the clarity, definition, sweet tone and it is the most accurate rig that I've ever heard to date. Got a sweet bass that just oozes old school? What about that axe that you use for the hi-fi tones that you need? Plug it into a similar rig and I personally don't think that you would have a problem getting what you need. It's probably not one of those rigs that would enhance the tone of a bass that needed a little help though or am I wrong about that? I'm sorry that I'm so late to the party but we just don't normally get to try gear like that in Denver. Well at least I don't!
