Yamaha Guitar Group, Inc.’s (“YGG”) trademarks, logos, and service marks are valuable assets that we diligently supervise and protect. We understand that some third parties need to use our trademarks to refer to YGG’s products. Therefore, we developed these guidelines to assist our business partners, customers, and other third parties and to answer some of the frequent questions we receive regarding the proper usage of YGG’s trademarks.

These guidelines are designed to ensure the proper usage of YGG’s trademarks and to prevent consumer confusion. Since we cannot address every question that may arise, these guidelines are not intended to be a definitive or exhaustive statement on the proper usage of YGG’s trademarks.

These guidelines apply only to use of YGG’s trademarks in word format. Third parties may use YGG’s logos or other trademarks with design elements only under the terms and conditions of an agreement that permits the use of YGG logos, and in that case, it must conform precisely to a logo specimen provided in the agreement.

Proper Use of YGG's Trademarks

Third parties may use YGG’s trademarks to identify YGG’s products and services, provided such references are true, fair, not defamatory, and not misleading as to YGG’s affiliation, endorsement, or association with such third party or third party’s products and services, and provided these guidelines are followed:

  1. If true, you may claim that your product “works with” or is “compatible with” a YGG product as long as such statement does not create consumer confusion about the source of your product.
  2. Referential uses of YGG’s trademarks must be presented in the same font and font size as the surrounding text and must not be emphasized (i.e., do not underline or use bold or italics).
  3. You must use the proper form, representation, trademark symbol, and attribution credit acknowledging YGG’s trademark ownership.
    1. Proper Form = Adjective (not a noun or verb) and Singular (not plural or possessive)

      Always use YGG's trademarks as a noun modifier, not a noun or a verb.

      Correct: Variax® guitars are revolutionary instruments.
      Not Correct: Variax is turning guitar history on its ear.

      Always use YGG's trademarks in their singular form, not plural or possessive.

      Correct: I bought two POD® digital effect devices.
      Not Correct: I bought two PODs.
      Not Correct: The POD's versatility is what makes it unique.
    2. Exact Representation

      Always reproduce YGG's trademarks exactly as registered. Do not change the spelling, capitalization, spacing, or punctuation.

      Correct: StageScape StageSource AMPLIFi Sonic Port
      Not Correct: Stagescape Stagesource Amplifi Sonicport
    3. Trademark Symbol: "®" for registered trademarks; "™" for unregistered trademarks.

      Please use the appropriate symbol — superscripted, without a space, and to the immediate right of the trademark — following the first use of the trademark. Second or subsequent uses do not need these symbols.

      For ease of reference, set forth below is a complete list of YGG's registered and unregistered trademarks as of the date set forth above. For a more complete and up-to-date list, you may contact YGG’s legal department in writing at
