With the Fender Pro Junior IV Lacquered Tweed, Fender presents the next evolutionary stage of the compact recording secret weapon. Based on an extremely linear single-channel tube circuit, the compact guitar amplifier delivers a particularly dynamic sound that reacts sensitively to the style of playing and the electric guitar used. Thanks to the modified volume control, the point at which sound of popular crunch breaks open can be determined even more precisely. The Fender Pro Junior IV's 15 watts of power gained from two EL84 tubes are also output via a Jensen P10R loudspeaker. With a ten-inch diaphragm diameter and an Alnico magnet, the speaker delivers a warm tone whose rich midrange and even treble perfectly support the character of the guitar amplifier.
