The P10R-F was designed by the Jensen factory in cooperation with Fender for the reissue of the Fender '57 Bandmaster and the 20th Anniversary Vibro King. The goal was to design a P10R speaker with a more broken-in, worn sound straight out of the box. The P10R-F has a smooth, round top end and a full-bodied low end response, it distorts at lower levels; and still maintains the vintage classic tonalities of the legendary P10R. Loose lows, subdued mids, and subtle highs with a crunchy overdrive feel. Warm, mellow tone with less bite and brightness than the standard P10R. In overdrive, this one eases into a creamy distortion. 10 in., 8 ohm, 25 watts. AlNiCo.
