I have just acquired a new (to me) Williams 400 U-12. This was once owned by BJ Cole and still set up how he had it. I've not asked BJ if this was made specially for him yet but maybe someone on here knows some info on it? It's stamped "438" under the headstock. I'm guessing its a late 90s model maybe from other photos online?
Here are some photos

I'm thinking of swapping the E levers from the left knee over to the right knee like my Excel U-12. Any advice for doing this your self? I always find setting them up is a bit of a nightmare getting them to pull together (i did on my sho bud anyway) is there a correct procedure for setting up to E pulls from scratch? Looks like there are enough Rods underneath to put it back to standard.
Another thing which is becoming a pain is the 6th string appears to keep going out of tune when using the B pedal. I cant tell yet if both the open string and the B pedal are going out of tune or it just up the open string.
The 6th string (B pedal down) seems quite out of tune with the open E string. I'm finding myself in a bit of a tuning circle between open string, Pedal down, playing it for a bit then it seems a bit off. I'm not sure if the Excel is just better with its cabinet drop than the Williams or if there is a problem?
