Hi Steve, I've had The BB 414, 424x and 1024x. Loved them all. They all sounded great and we're super flexible with the powerful jazz pick up at the bridge.
I fell out of love with the look of them and sold them all and moved on to precision basses.
I did manage to buy the 414 back as that was my favourite and it's now getting regular gigging time along with the precisions.
Not tried the newer 434 but would 100% recommend the 414, 424 range.
Just be aware they can occasionally be on the heavy side.
