ไดเร็คบ๊อกซ์ Radial JDX Direct-Drive Guitar amp simulator for pedalboards, Eliminates need to bring an amp to the gig, 4 x 12 half-stack & open back combo tones, Employs Radial’s popular JDX tone shaping
The Radial JDX Direct-Drive™ is a unique and powerful device that emulates the sound of a guitar amplifier while doubling as a direct box. Unlike a typical direct box that merely transfers the sound of the pedals to the PA, the Direct-Drive simulates the tone and feel of a real guitar amp, producing a much more realistic sound. In other words, with the Direct-Drive on your pedalboard, you can do a gig without carrying an amp to the club.
The design begins with a traditional ¼” guitar input and passive thru-put to feed a stage amp. This is then followed by a dedicated tuner output that is buffered in order to eliminate loading on the pickup or noise from the quartz clock. The guitar signal is then passed through a series of carefully sculpted filters to create Radial’s signature JDX tone. This is modelled after the sound of a Shure SM57™ in front of a Marshall™ 4×12 cabinet.
The Direct-Drive goes further with two more voicing settings: the first adds a vintage Marshall™ tube head character to the signal path while the second delivers a tone reminiscent of an early Fender Twin™. The two amp tones can be further tailored using a presence switch for extra sparkle. The guitar signal exits the Direct-Drive via either a ¼” guitar-level output or via a balanced XLR to feed the PA. The direct box output is outfitted with a 180° polarity reverse switch to help phase-align monitors with the stage amp along with a ground lift switch to help eliminate hum and buzz caused by ground loops. The Direct-Drive may be powered using a standard 9V power supply or typical pedalboard power brick.
The Radial JDX Direct-Drive… one small step on a pedal board, one huge step for the guitarist!
