Trying to re-fit 5th Knee Lever (LKV) on my BMI SD10 to drop Bs to Bb but can't get them to just drop the semi-tone. Tried everything I know but they are still lowering way too much and there's no stop fitted on the lever. Tried contacting BMI about another problem recently but no response so no point in trying to contact them about this. Would be grateful for any suggestions Thank you in advance.

I don't understand.. If you keep backing off the nylons on Both B lowers they will get to the point where they aren't even contacting the changer, and won't lower at all. that goes for ANY all pull changer.

. Also try different holes on the bellcrank, if you have not already done that.


If you back them ALL the way out and you are still lowering too much, the Pull rods are too short.. or something.

If you want to lower with shorter amounts of travel, its very simple to add an adjustable stop on the bellcranks as well.
You should NOT have to do that though.. Sounds like the nylon tuners need to be backed off more... bob

On my BMI, for both Bs I am using the 5th hole on the pullers/bellcranks. That's the hole closest to the floor when the guitar is assembled and set up. On the changer end, for both strings, I am using the top holes, closest to the raise holes.

.017 and .036W strings.

Roy, take the nylon nut ioff and make sure the metal spacer is in place and does not go through the changer finger. Make sure the bellvrank on the cross plate is facing the proper way, you can look at it he others to determine this. Call or email Don at BMI , I’m sure he will get back to you.
