I will try to explain from my limited point of view if i may.. I hope i do OK.
And I hope Jimmy wont cut me in half if he reads this or if i explain it wrong... ..
But I am around him, and have my ears to the proverbial ground in what he does..
The VINTAGE bridge was not easy to develop.. The "NEW" vintage style bridge is not that new at all for him .. It was in development for about 4-5 years..
And it is what he, Jason Langley and I originally wanted for the vintage style LG years ago, when i pressured him relentlessly to make me a 5 string bass.
As simple as it may look, It cost alot of $$ to get it blueprinted and and samples made and finals made and ready to use.. It Literally took a few years..Not only does he build and do repairs but there is normal life stuff too..
It could have gone faster but being an indy builder, he dose not have the luxury of unlimited cash flow for R&D... and it was $$$$$. Thousands....
And the first pieces were not the finals.. he went back a few times to get it right...And since it was his plans, every time there was a change it cost more money and time.. You can partially blame me for that..
I CAN NOT speak for Jimmy , but it was perhaps a toss up of not making a bass because he did not have the bridge that he wanted for the vibe of his LG product, or going with another type to get his niche on a design out there..
Now even the "B" style bridge is slightly different.. And even went through a few metal changes before finals..
I hope i did not stir up a hornets nest here..
At the risk of being run out of town...... I find the styling of these basses a bit confused. I'm not in any way running them down, Paul Turner sounds great on that Jamiroquai video. I keep reading about Jimmy's vintage fender fetish (eg the truss rod adjuster) but some of the bridges don't fit with that vibe, the head stock is... an acquired taste and the pick guard doesn't look right with a cutout for a non existent control plate and five knobs. My personal favourite of the ones I've seen is the 5 knob layout and no pickguard. For me it allows the instrument to take on it's own, more coherent appearance.
Don't flame me guys, I'm just expressing another opinion on the very subjective area of appearance. I'd love to play one of these things and if they sound as good as everyone says I'd own one regardless.
