NOTE 1
Sherman = Hardened Tool Steel
The Sherman Tremolo System uses hardened tool steel for all highly stressed components, i.e. the bridge plate, saddles and string clamps.
What is tool steel?
Tool steel is a unique class of steels designed to perform under a variety of adverse conditions without suffering any type of damage, wear, dulling or metallurgical changes. Tool steel is designed to withstand constantly changing temperatures, shocks, high loads concentrated at specific areas and continual contact with abrasive materials. When the tool steel used on components for the Sherman Tremolo System is hardened, it becomes hardened throughout.
Others = Case Hardenable Steel
The others use case hardenable type steels. When steel is case hardened, the steel attains hardness only to a specific depth. This depth can vary widely from very shallow to very deep. But underneath this (usually shallow) layer of hardness is soft steel.
Additional Features Unique to the Sherman Tremolo System
NO COMPROMISE DESIGN APPROACH
The Sherman Tremolo System was designed from the begining to be a "no compromise solution," meaning no shortcuts were taken to address the flaws inherent in tremolo systems. This uncompromising approach makes the Sherman Tremolo System the longest lasting, most wear resistant, best feeling, best playing and most responsive tremolo system available today. Admittedly, this also makes it the most expensive tremolo system available.
IMPROVED BRIDGE PLATE, SADDLES AND STRING CLAMPS
Because of the high quality tool steel used:
 The string clamps will not mushroom, show string indentations or wear out.
The bridge saddles will not show string indentations or wear out.
The bridge plate pivot points will stay stiletto sharp and will not wear out.
BRIDGE SADDLE REDESIGN
The bridge saddle has been redesigned to improve the internal stresses at work on the saddle when the string clamp is forced against the string to lock it in place so the bridge saddle will not break. The internal portion of the bridge saddle is now round to more evenly distribute the forces pressing the string clamp against the saddle. The string clamp is also round and is T-shaped at the bottom to ride in a channel underneath the saddle so it will not fall out.
INTONATION
The intonation can be easily adjusted with all of the strings at pitch.
TUNING STABILITY
The Sherman Tremolo System has superior tuning stability that rivals the best locking nut and non locking nut tremolo systems available today. The Sherman Tremolo System is the first double locking tremolo system without a locking nut. See the Sherman Tremolo System page on the Web site for further information.
CLAMPING THE STRING AT THE BRIDGE
The Sherman Tremolo System clamps the string at the bridge because doing so gives the most sustain and improves tuning stability.
ADVANCED TREMOLO ARM
The Sherman Tremolo System uses a new patented arm assembly that gives excellent control over the tremolo.
Advantages:
The tremolo arm assembly provides exceptional "feel."
The rotational tension of the arm can be set and help indefinitely.
The height or angle of arm can be adjusted.
Features:
The arm socket design allow for smooth and consistent arm swing.
The arm can be installed and removed easily.
ADVANCED TREMOLO ANCHOR
The Sherman Tremolo System uses a new patented tremolo anchor that provides unparalleled structural integrity, yet allows for simple adjustments of the tremolo balance.
Advantages:
The Tremolo anchor provides permanent structural support for the tremolo system.
The traditional method of using wood screws, which could strip out when adjusting the tremolo, is replaced by permanently anchored thread shafts.
The tremolo balance is adjusted easily and precisely without effecting the structural integrity of the tremolo and the guitar body.
The tremolo anchor improves the transfer of string energy enhancing tone and sustain.
The tremolo anchor helps give the Sherman Tremolo System its remarkable pitch stability.
Features:
The Sherman designed spring claw and anchor shafts are manufactured from high quality stainless steel and then hardened.
The spring claw locks in place along the anchor shafts sleeved nuts provide smooth movement of the spring claw along the anchor shafts.
Up to five springs can be used to obtain the desired pivoting action and responsiveness of the tremolo.
