Hohner B2A high action

Hello,

I have some high action problems with a Hohner B2A. The saddles are set to the deck and I have still 1/8 on E at 17th fret. I usually go for 5/64 on that E. Any suggestions on how to reach a lower action? It's a neck thru (and it has a little hump at the last frets. But thats another problem .

Cheers

 

Sorry about leaving that out.
Yes it has a truss rod and it's working fine. The measures above is when the relief is 12 thou at 7th fret pressing down 1st and 17th fret. It's the normal setup for me.

 

I guess I'll just file down the bottom of the square saddle blocks. Any objections?
