JPF Regent 25

JPF Regent 25 Guitar Amplifier Head
The Regent 25 employs the same basic topology as the other amps in the JPF range but is powered by two Gold Lion Reissue KT66s, to give 25W before the onset of clipping.

Currently available as a head , 2 x 10″ or 2 x 12″ combination amplifier format.

Prices:

Head: £875

2 x 10″ combination with ceramic speakers:£1175

2 x 12″ combination with ceramic speakers:£1225

2 x 10″ combination with alnico speakers: £1375

2 x 12″ combination with alnico speakers:£1425

JPF Sir Charles 15

JPF Sir Charles 15 Front View

The A to ZZ of country, blues and boogie…

The Sir Charles 15 is designed around a pair of 6V6 output valves. 6V6s were extensively employed in  the lower powered classic American amps that kick started Rock ‘n’ Roll. The simple ergonomics – just volume, treble and bass controls – and 15W of power at the onset of clipping, make this an ideal gigging amp, allowing you to get power valve distortion without being told to turn down by the soundman!

Prices:

Head amplifier: £750.00

1 x 12″ Combination amplifier with ceramic speaker: £1000

2 x 10″ Combination amplifier with ceramic Speaker: £1050

1 x 12″ Combination amplifier with alnico speaker: £1100

2 x 12″ Combination amplifer with ceramic speakers: £1100

2 x 10″ Combination amplifier with alnico speakers: £1250

2 x 12″ Combination amplifier with alnico speakers: £1300

From British Invasion to Monster of Rock…

The King Charles 30 employs the same pre-amp topology as the Sir Charles 15, but has EL34 valves in its output stage to provide a gnat’s under 30W of power before clipping. EL34s are the power valves that helped define the “British sound” and are used in Marshall, Hiwatt, Selmer and many Vox amps. More head room than the Sir Charles 15, the King Charles is voiced to enhance the “chimey” qualities of the EL34, and like the Sir Charles 15 transfers smoothly from clean to overdrive.

Unique Amplifier Design

JPF’s Amplifiers have been created with the guitarist in mind. Our inspiration draws our experiences repairing vintage amps at Angel Music, one of Denmark Street’s leading high-quality guitar sellers.

We took the opportunity to learn from a broad range of guitarists, from weekend warriors to stadium stars, what they truly want from their amps. Using years of expertise in the fields of broadcast technology and research, our design process has involved hours of painstaking R&D which includes extensive feedback from guitarists and music producers, real innovation, attention to detail, many hours of listening tests, and over 10,000 cups of tea!

…innovative design…

Rather than rehash existing designs, JPF have developed a unique combination of the classic circuit elements used in vintage valve amps of the 50s, including: Selmer, Gibson, Vox, Gretsch/Valco (!?) and Fender. The philosophy behind these amps was to design a simple circuit that incorporates the best characteristics of classic valve amps, but with the hindsight of an extra 30 years of technological advances since these classic valve amps were manufactured.

Thus we’ve used the best modern materials and construction techniques (e.g. PTFE circuit card, toroidal mains transformers,  star grounding etc) combined with elements that gave the classic amps their sound (e.g. carbon composition resitors and valves (!)).

…at the gig…

The small-box head format and use of lightweight materials means these amps really are portable, whilst our 1 x12″ combo is still very manageable. OK, OK, the 2 x12″ is a bit weighty, but that goes with the territory.

All our amps have been extensively road tested during the design stages, and have passed with flying colours.  We are so confident that our amps won’t let you down, that all our amps come with a 5-year transferable warranty.

…in the studio…

The unpleasant tonal artefacts and high levels of noise that many vintage, and even contemporary, amps suffer from have been painstakingly engineered out of our amps. The low noise circuitry and quality of tone allow recording engineers to place microphones without compromise rather than fighting noise, rattle and hum.
