Classic amp tones in a compact pedal

The Direct-Drive is an amp simulator designed for your pedalboard, providing a realistic amp tone that can be connected directly to the PA system. Three amplifier voicing options are provided: the first is the popular JDX tone which simulates the sound of an SM57 microphone on a 4×12 cabinet. The second setting is similar in character to a British tube head amplifier, while the remaining tone is modeled after a clean twin combo amp. With three classic voicings available, the Direct-Drive provides a natural amp tone through the PA system and consistency from night to night.

In many ways, printing out the specifications of the JDX Direct-Drive is a moot point. The Radial JDX Direct-Drive has been designed to ‘sound good’ by emulating the sonic character of iconic guitar amps. In other words, the Direct-Drive sound has absolutely nothing to do with a ‘flat frequency response’ or the typical specifications that engineers will consider. It is, in fact, the opposite. We have however taken the time to minimize distortion so that the Direct-Drive delivers the signal correctly without introducing noise. We also felt it worthwhile to show you the resulting EQ curves so you can get a first-hand view of how we will ruin your sound! Have fun!
