Radial Reamp HP: Reamping Made Foolproof

The Radial Reamp HP is a compact, passive Reamper that takes the signal from a headphone output jack — on an audio interface, a laptop, or a mobile device — and converts it to feed mono guitar amps and effects pedals. Reamping used to mean re-patching cables behind the desk and matching impedances by trial and error; the Reamp HP removes all of that friction. You assign a recorded track to your headphone output, plug in, and send it straight to a real amp. For anyone who has wanted to chase new tones after the take is already recorded, this little box makes the whole idea suddenly effortless.

What Reamping Is and Why It Works

Reamping is the studio technique of taking an already-recorded clean track — usually a guitar or bass DI — and playing it back out through a real amplifier and pedals so you can capture a fresh amp tone without re-performing the part. The catch has always been signal matching: a line-level or headphone output does not present the impedance and level an amp's instrument input expects. The Reamp HP handles that conversion with a passive isolation transformer, so the track hits your amp looking like a guitar again, and your tone decisions stay open long after the performance is locked.

Reamp Straight From a Headphone Jack

The defining trick of the Reamp HP is that it works from a headphone output, the one jack every interface, laptop, and phone already has. Instead of tying up a dedicated line output or crawling behind your rig to repatch, you simply assign the track you want to reamp to the right channel of your headphone output and connect. If the source is stereo, the onboard mono sum switch collapses it down to the single mono feed an amp needs. It is a workflow you can set up on the fly, in seconds, without disturbing the rest of your session.

Two Inputs for the Studio and the Sound App

The Reamp HP carries both a 1/4" and a 3.5mm input, so it is not limited to a studio interface. Plug in a smartphone or tablet and you can feed a synthesizer or sound-creation app through your favorite pedals and amplifiers, capturing textures that never existed as a clean DI in the first place. That flexibility turns the Reamp HP into a creative playground as much as a corrective tool, opening up new sounds from whatever device is closest at hand.

Clean, Quiet, and Road-Ready

Because the Reamp HP is transformer isolated, it naturally breaks the ground loops that cause hum and buzz when you tie a computer or interface to a grounded amplifier, and a dedicated ground lift switch is there for the stubborn cases. A level control lets you dial the output precisely so your pedals and amp are driven just right, and the whole circuit is passive, requiring no power or batteries. Housed in a 16-gauge steel chassis and outer shell, it is built to survive the studio floor and the road alike.

Who the Reamp HP Is For

The Reamp HP is aimed at home recordists, project-studio owners, guitarists, and producers who want the creative payoff of reamping without the technical hassle or a large investment of space. Use it to re-tone a guitar or bass part after tracking, to audition amp and pedal combinations during mixdown, or to route a mobile sound app into real hardware for something genuinely new. If you already own a DI and have shied away from reamping because it seemed fiddly, the Reamp HP is the box that finally removes the excuses.
