A guitar model can be called a hard-tail when it doesn't feature a tremolo system or vibrato tailpiece but a fixed bridge/tailpiece. The term mostly applies to guitars which usually do have a tremolo, such as Fender Stratocaster type guitars and Ibanez RG models and S models. Most of these guitars feature a 'hard-tail' style bridge instead of a tremolo when being 'fixed'. In Ibanez catalogs the term Fixed Bridge is used for either Ibanez branded hard-tail bridges or the quite similar Gotoh GTC101 bridge.
