Radial Engineering JDX Direct-Drive Amp Simulator & DI Box
The design begins with a traditional _" 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 SM57ª in front of a Marshallª 4x12 cabinet. The Direct-Drive goes further with two more voicing settings: the first adds a vintage Marshallª tube head character to the signal path while the second delivers a tone reminiscent of an early Fender Twinª. 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 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.
As with all Radial products, the Direct-Drive is made to handle the rigors of professional touring with 14-gauge steel throughout. This not only helps prevent damage to the internal PCB, it also reduces susceptibility to noise from external magnetic fields. The Radial JDX Direct-Drive... one small step on a pedal board, one huge step for the guitarist!
