So, I bought 1978 Yamaha Lawsuit P-Bass (Pulser Bass 400) a few months back. It has a bowed neck, but I wasn’t too worried as it wasn’t that bad. The seller was cool (it was shipped from Japan) and gave me a partial refund for the inconvenience since he advertised the neck as straight in the listing. Now that I’ve had time to mess with it, the bow isn’t coming out very easily. I tried putting it in clamps after removing the truss nut and then reinstalling the nut after I achieved appropriate back bow...went right back. Then, I tried adding washers...I’m up to 5 (thin) washers and it’s made a dent in the bow, but not much. I have read about maybe leaving it in the clamps for several days, but haven’t tried that yet. anyone else dealt with a neck this stubborn?!
