Tonebone JDX Direct-Drive

The Radial JDX Direct Drive is an amp simulator and DI box offering JDX tone shaping in a steel housing. The Radial JDX Direct-Drive is a unique and powerful device that emulates the sound of a guitar amplifier whilst doubling as a direct box. The Direct-Drive simulates the tone and feel of a real guitar amp, producing a much more realistic sound. The design contains a 1/4" guitar input and passive thru-put to feed a stage amp. This is accompanied by a dedicated tuner output that is buffered 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, modelled after the sound of a Shure SM57 in front of a Marshall 4x12 cabinet. The Direct-Drive includes two more voicing settings of a vintage Marshall tube head character and a tone reminiscent of an early Fender Twin.
