The ultimate pro-grade bass combo amp, the Phil Jones Bass Double Four BG-75 Personal Micro Bass Combo packs a massive 70 watts of power, dual PJB NeoPower speakers, and loads of features into an ultra-portable, lightweight package.Designed with professional bassist in mind, the Phil Jones Bass Double Four is a pro-grade bass combo amp that offers exceptional power, tone, performance, and portability. What's more? This super-compact combo comes fully loaded with groundbreaking features and technology that sets this apart from the rest of the pack. If you need a high-quality practice amp that doesn't sacrifice tone or performance, the PJB Double Four has got you covered!
The Phil Jones Bass Double Four pushes 70 watts of power and signature PJB tone through a pair of PJB's specially-designed 4" NeoPower speaker--each equipped with independent PWM amplifiers. The Double Four also features PJB's revolutionary custom Rectangular Auxiliary Low Frequency Radiator (RALFR) and sports a heavily-braced enclosure with acoustic damping materials, which offers superior speaker performance while allowing the true, uncolored sound of your bass to be conveyed through the amp.
The Double Four comes equipped with an onboard 3-band EQ as well as a flexible 1/4" input that can adapt to both active and passive basses thanks to the Mute/Low/High switch. Jam along with your favorite tracks by plugging your mp3 player, iPod, etc. into the Aux Input, and adjust the volume via the dedicated Aux Level control. The Input Level knob allows you to adjust the volume of the bass itself while the Master Volume controls the amp's overall volume. For silent practicing, the Double Four also features a convenient built-in Headphone jack while the Line Output allows you to connect to a powered amplifier for additional power.
Driver and Amplifier Technologies
Driver and Amplifier Technologies Pushing PJB's expertise of using smaller drivers to get the ultimate bass sound, they applied their vast experience to an even smaller, "Neo Power" 4-inch driver built with precision of a Swiss watch. This 4" baby is able to cope with the extreme signals coming in from an amplified bass guitar. By using PJB's extensive R&D facility which includes the largest anechoic chamber in the bass guitar amplifier industry, and the KLIPPEL transducer measurement system, PJB was able to develop the perfect 4-inch transducer for their purpose. They analyzed the neodymium magnetic system, the cone behaviors at all frequencies in 3D representation, cone suspension and frame, until they achieved their goal. They then looked at the acoustic loading using the acoustic simulation software and calculated exactly the full power cone displacement at every frequency.
Each one of these 4" speakers are fed with its own Pulse Width Modulation PWM amplifier. PWM amplifiers are extremely efficient compared to the traditional analog solid state amplifiers, converting electrical energy to power using on the speakers instead of wasting it on hot. Since the amp is running at lower working temperature, the DOUBLE FOUR will give years of service long after other amps have faded away. By using dual amplifiers one for each speaker, the bass control is greatly improved since the damping factor (the amplifier's ability to put on the "brakes" to stop the speaker cone from overshoot) is doubled. The end result? A bass tone that is well controlled, punchy, tight and never muddy or bloomy.
To maximize its tiny cabinet enclosure, PJB designed a custom Rectangular Auxiliary Low Frequency Radiator (RALFR).
RALFR is a pneumatically coupled radiator loaded to the rear of the two 4-inch speakers that operates at the lowest bass frequencies only. It augments the output of the loudspeakers at frequencies from 30 to 150 Hz. It also reduces the cone excursion of the speakers, so power handling is greatly improved. The cabinet is also heavily braced internally and lined with acoustic damping materials. This damping prevents cabinet coloration that can interfere with the true sound of your instrument. Now, what you hear from the DOUBLE FOUR is the most realistic amplification of your instrument.
