The Ledger

Grand Piano
Offerings

Two ways to bring a DS Standard keyboard to a grand piano. In both cases the instrument’s action travels to Titusville, Pennsylvania for precise measurement before we begin work. We provide the crate.

Complete New Action

Concert Grade

US$16,800

A complete new action with its own stack, built around new hammers and wippens. Interchangeable with the original keyboard in about five minutes.

Initial installation typically takes an afternoon or a day; technicians spend considerably more hours over time to regulate and voice the action to concert level.

New hammers and wippens on a new action stack

DS Standard Keyboard

Studio Favorite

US$10,800

A new DS Standard frame mounted with the piano's original hammers and wippens. Preserves the instrument's voice and can be reversed at any time by a competent technician. Because the build is made to measure, we will have your action for approximately three months.

Precision Engineering

Bass to Treble,
by the Millimetre.

Every DS Standard keyboard is precision engineered using the same computer driven manufacturing processes we have refined over three decades. The result is quiet, consistent, and remarkably easy for a technician to live with.

The design of key leveling alone is a small piece of genius. What used to be a delicate, patience testing adjustment has become a fifteen minute job, and every other regulation step benefits from the same dimensional discipline.

From the strength of the keys through the response of the action, every component is built to meet the standards of serious professional use, and to keep meeting them decade after decade.

“As the piano technician at Ohio University, I am pleased to add my voice to those praising the DS Standard keyboards. From a technical standpoint, these pianos are a joy to work on. The engineering is extremely accurate in all regards. I am continually impressed with the precision and manufacture of all the components.”

Institutional Impact

“In 2014, the School of Music at the University of Central Oklahoma was extremely fortunate to acquire a DS6.0 keyboard action fitted to a Steinway D concert grand. Students with smaller hand sizes have since been able to unhesitatingly take on and confidently perform repertoire which would normally have been off limits.”

Dr. David ForbatProfessor of Piano, University of Central Oklahoma, School of Music
