The JDX Direct-Drive from Radial Engineering is an amp simulator for your pedalboard, giving you the tone and feel of not just one, but three different amp/cab configurations. With this pedal, you can very well avoid lugging an amplifier around town from gig to gig altogether, though the pedal does provide a passive thru-put to feed unprocessed signal to your onstage amplifier, should you choose to go that route anyway. A dedicated, buffered tuner output supplies any electronic tuner with guitar tone without extra loading on your pickup, or without introducing noise from quartz clocks.

The pedal itself uses carefully tailored filters to create faithful emulations of caps, combos, and amp/cab configurations. You have choices here. You can select the COMBO setting, which models an early Fender Twin, or STACK mode, which mimics the timbre of a Marshall tube head feeding a 4x12 cabinet. JDX 4x12 Mode gives you the cabinet only, its tone specifically modelled to give you the sound of a cabinet mic’d by a Shure SM57 dynamic microphone. Both COMBO and STACK modes can receive even more tonal juicing from a special, two-position toggle switch, which lets you boost the highs for extra sparkle.

For outputs, the pedal provides a standard, phone type 1/4” jack and a balanced XLR DI for feeding processed signal to the house, a mixer, or a recording interface. A 180° polarity-reverse switch allows you to phase-align the signal with your onstage amplifier, if it happened to be out of phase, while a ground switch eliminates hums and buzzing often associated with ground loops. The pedal runs off of 9 VDC, either from a pedalboard brick, or from a separately available power supply.

Controls at a Glance
POLARITY Toggleswitch: This toggles pin-2 and pin-3 on the XLR output, helping you phase-align your amp with stage monitors.

 

GROUND Toggleswitch: This lifts Pin-1 on the balanced XLR output to help reduce the hum and buzzing caused by ground loops.

AMPLIFIER Toggleswitch: Part of the Tone Voicing section, this three-position toggle offers three different amplifier emulations. COMBO models the tone of a Fender Twin, STACK mimics the timbre of a Marshall amp/cab configuration, and JDX 4x12 emulates only the sound of a 4x12 stack.

PRESENCE Toggleswitch: Also part of the Tone Voicing section, this two-position switch provides extra sparkling highs for the STACK and COMBO settings. 

Connections at a Glance
THRU: Use this to feed unprocessed tone to an on-stage amplifier, or a dry 1/4" studio DI input.

 

TUNER: This Hi-Z always-on output can be used to connect to an electronic tuner.

XLR: This balanced output is useful for feeding processed signal to a PA system or the XLR input of a recording device.

                                  Easy assemble and not to big!
                                  Color: Black, Size: 132in-Large Metal Base
                                  I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!

                                  Fair Quality, Hour and a half build
                                  Color: Black, Size: 132in-Large Metal Base
                                  Key things: It does (more or less, not completely) fold in on itself, it does block nearly all visibility (especially from an angle), it was only about an hour and thirty minutes to put together, and it is light weight. Do I recommend? Yeah.

                                  Assembly was a bit rough
                                  Color: Black, Size: 132in-Large Metal Base
                                  It is serving the purpose it is bought for. However the assembly was harder than it should have been. Joining the parts A and B (two iron pipes) was very hard. We can't use any tools to do that and it has to be done manually and every joint was very tight and very hard to to do. I had to struggle to make 24 joints for the length I need. At one point I was going to return it, but I needed it very badly so continued with the assembly.
