I’ve had one of the original CV Precisions, and a Tony Butler Sig V4. If I had to say which felt more substantial I’d go for the V4, it just had a more “reassuring” feel about it, but then that may be due to being modelled on a 70s Precision, they were quite chunky! That’s not to put down the CV though. Both basses sounded great, and played great too. I’d say the best way to choose between them is go for the colour you like most as aside from the “which would I choose to hit someone with” factor there really wasn’t enough between them to recommend one over the other.
