Hallo to all.I have an Alembic europa bass. It is time to set up it.I would like to help me with instructions cause i never set up a bass like this in the past (2 trass rods etc.)I used to pay for set up but I would like to do it alone.Thanks

You'll find a most excellent step-by-step instruction in this classic thread, Joey's Post on Setting Up Your Bass.
 
Have fun, and see how low you can go!
