The Leveling-Sampling Kit Box holds everything you need except a Key Level Stick to sample for setting up on the bench and level keys. This can be purchased in the Sampling Bundle or separately since one or more of the tools it carries you may already have. These include 8 10mm Keysteps and 8 12mm Keysteps (new slimmer dimensions). 2 Rocke Sharp Leveling Blocks to replace 2 of each size Keystep, no longer needed. A WNG Dip Tool to weight kissing samples of strike and a 200mm Gram Weight to offset string #3's displacement in that process. Finally, an 8mm Combination Ratcheting Wrench to adjust the Keysteps while in place under keys and 2 100mm machine screws for storing front punchings removed to allow for sampling.
