The Eden WTDI is pretty good, but "that Eden sound" has never been my thing. The Avalon U5 is also a nice unit, used one several times, but never owned one.
I've tried several other preamps as well, and my Darkglass B7K is my favorite by far. None, a little or a lot of overdrive/grit, 4-band EQ with great voicings and the two switches to instantly change up the sound. My urban gospel band just finished up recording tracks for a new CD and I brought it in for a session... the recording engineer was pretty impressed and even asked if it had a tube in it. And this wasn't a "basement" studio, we were at
www.side3.com. They have a room full of nice gear, so it's pretty hard to impress those guys.
I've also tried a couple of the Sansamps (BDDI, PBDDI, VT Bass - all very "sansamp"), a Rusty Box when it was all the Talkbass hype (and found it overly aggressive and cold, IMO... flipped it in less than a week), a Tubeworks BlueTube/DI combination (switched the 12AX7 to a 12AU7 and it's pretty killer) and an Aguilar Tone Hammer (probably my favorite after the B7K). If the Tubeworks had a DI, it'd probably be a "desert island" pedal for me.
Never tried that Bassbone, unfortunately. You might also check out the Phil Jones Bass Buddy, a fellow pit musician bassist has one and he's had some very positive comments about it. Also, the 3Leaf Enabler seems to be a very good unit... I VERY much want to try one out. I have four other 3Leaf pedals and they're excellent.
