I know you were digging the Darkglass... what are the diffs you're hearing?
I really did like the DarkGlass but ever since I've had the bass I've been thinking "what would the Bart pre sound like in this bass?"
There's not as much difference as I would have thought (tone wise). The Bart is a bit more easy to fine tune the Mwah that I like and quite honestly I've always really liked the slightly compressed tone that a Bart pre has. The Darkglass is really clear and open sounding to my ears and the Bart kind of naturally colors and compresses the tone but just the way I like to hear fretless. It's probably got a lot to do with the fact that every Fretless that I've had (prior to the Darkglass) has had the Bart preamp installed (other than one that had the Audere which didn't stay in it long). I also prefer the blend control over the V/V that the Darkglass pre had (although I suppose that I could have changed that to a blend and master volume).
At any rate, I really like the sound of the bass with the Bart installed (and the Darkglass has already been sold and shipped).
The Bart also has a nice A/P feature that actually sounds really nice too.
