Received my bass yesterday. Already 100% blown away by this bass. I've been playing everything with it. Construction, sound, feel... EVERYTHING about it is top notch. If I wasn't a bassist for life I'd probably buy the cheaper Wav but I'm glad I went with the CR series.
I ordered my CR4M from Lemur Music who didn't have them in stock at the time so mine came directly from the factory. Instead of the piezo vert/horiz toggle switch the CR's now have a piezo horiz/vert blend knob just like the EU Series. I guess they changed that on the CR's since coming out with the EU's.
Day 3 - 3 things I have noticed so far:
1) Tuning machines have a lot of backlash. I have Schaller's on a pbass fretless and a tele. They are very precise, these aren't.
2) I'm catching a faint feedback noise/hum from what I believe is the piezo pickups. I don't know if its the settings I'm choosing but its only when notes on the D and G strings are played (higher notes) and with the piezo pickups. I'm playing through headphones so its not the usual feedback I'm used to.
[Fixed with foam under strings between bridge and body]
3) D and G strings are much brighter than the E and A... and the E will sustain forever as it is.. the D and G strings will actually get louder if you let them sing. Some sort of dampening on the strings is needed when played under most situations/bands - you can sustain a note longer than a synthesizer (lol). I'm sure a lot of this is resolved with DB type strings as mentioned by others earlier in this thread. [Foam helped].
Nothing to shy anyone away from the CR series but things I have noticed.
Edit: I found that the overtone/feedback was the D and G strings resonating between the bridge and where the strings come out of the body. Piece of foam to dampen the strings took care of it.
Day 4.. or is it 5?:
If you'd like to hear me attempting to play my CR4M check out Brighter Days on my
Link Removed. Song was written and recorded by a friend of mine
Link Removed I added the bass after the fact with his permission. This recording was done the first night I had the bass and I'm far from being a capable fretless player much less a DB player. As much as I hate fret markers - thank you for the dots! I'd be pretty lost without them. Last time I touched an upright was about 20 years ago.

Anyone worried about construction can see that issues previously mentioned in this thread are not apparent in the pictures i posted.
Well my very last post was saying that I bought Pirastro Orchs ( a great recommendation from Francois) and didn't have to change anything when I put them on!
Which ones are the Orchs?
Pirastro lists these steel strings:
Permanent
Flexocor
Original Flexocor
Flat Chrome-steel
Original Flat-Chrome
Chromecor
Jazzer
Okay then.. figured it out myself.
