I'd written a big long reply, but then the electricity went in my office and lost it all.
To summarise....
I guess they are special order. You can customise it anyway you want. I had mine in 13 days, but that includes about a week of nothing when I was working and couldn't get up to the factory to order my stuff. I'd reckon lead time would be a week or just under.
Vintage voiced? Running the bassman gets a nice thumpy vintage sound, but they can also do very clean hi-fio schtuff.
Monz and Butler on here have different speakers to me and Ste, but if you ring them they will ask you what you want and what sound you're going for, and they won't rest until you're happy!
It may look like us lot that have them are ejaculating all over them, but they really are necta!
