The P10R is very important in the history of Jensen speakers. Its shimmering, yet throaty and vibrant tone is one of the signatures of the Tweed era and inspired the start-up of the British tones. It was the first speaker reissued by Jensen, presented to a restricted panel of partners at the 1999 Summer NAMM show. The P10R is the speaker that contributed to the magical tone of the 4x10 Bassman® Tweed amps, the 4x10 Super Tweed Amps and the equally mythical 3x10 Bandmaster® amps.

Guitarist Description: Rich, warm tone. Accentuates the higher frequencies in sparkling detail.

  • Lows: Loose
  • Mids: Firm
  • Highs: Smooth
  • Overdrive: Crunchy

Bought these to replace the four tired CTS 137-735 speakers in a '67 Fender Blackface Super Reverb amp that was recapped in 2007. These new Jensens sound very close to the CTS speakers and will only get better after break-in! Have experience with these P10Rs in three other amps and they sure didn't disappoint...very happy!
