TCX Series Marching Tenor Heads from Evans are designed with volume and tonal clarity in mind. This head uses 2 plies of a 7-mil clear film with a full overtone spectrum, expressly targeting a wide tuning range designed to work for any show.

Using Evans' 2-ply alignment and Level 360 technology, these heads are made to be extremely consistent and max out on resonance and sustain, even at different tunings and tension levels. This also has the side effect of making them hold tuning reliably!
