t.bone is the store brand of European gear retailer Thomann.
The company offers a wide variety of pro audio products under the t.bone brand, including wired and wireless microphones.
The microphones are familiar to fans of inexpensive import brands such as Nady and Apex, and in fact are lookalikes to many such models. For example, the RM700 ribbon is nearly identical to the Nady RSM4.
Other models attempt to reproduce studio standards, such as the Shure SM57 (t.bone MB75).
All the t.bone models are inexpensive. As of June, 2011, the most expensive single microphone in their catalog is the SCT2000 tube mic, for €279.
