Radial Tonebone Bones Twin City

A Modern ABY Designed for Two-Amp Rigs

The Twin-City fits within Radial's approach: offering an ABY switcher that doesn't just route the signal but protects the tonal quality of your guitar in often demanding setups (two amps, long cable runs, loaded pedalboards). Its key asset is the combination of a Class A buffer and Drag Control, designed to recover the "feel" of a direct guitar-to-amp connection while benefiting from reliable A/B/Y routing.

Who It's For and Usage Contexts

The Radial Tonebone Bones Twin-City is aimed at guitarists (and bassists) who want to use two amps without compromise : clean and crunch set, wet/dry (effects in one amp only), stereo "on stage," or a main amp with a backup ready to take over. Live, it simplifies configuration changes without unwanted noise. In the studio, it allows layering textures (a bright combo + a darker head, for example) and capturing a wider sound while maintaining a stable signal foundation.

Controls, Switching, and Key Functions

The Twin-City combines simple ergonomics with essential functions for a pro rig. The Toggle footswitch selects the active amp (A or B), while the Both footswitch simultaneously activates both outputs. On the "problem-solving" side, you have a Ground Lift to reduce hum caused by ground loops, and a phase inverter to align your two amps when used together. Finally, the Drag Control adjusts the interaction between your pickups and the system input, very useful for preserving attack, brightness, and dynamics, especially with long cables or a dense pedalboard.

The Sound

This is not about an effect "color" like overdrive or delay, but about signal integrity. The Twin-City is designed to remain transparent and responsive to playing: sharper attack, better sustained highs, more stable lows, and a dynamic feel closer to "guitar straight into the amp" than many passive ABYs. The Drag Control allows fine-tuning this sensation according to your guitar, pickups, and amp. This type of tool is found in rigs of artists who use multi-amp setups on stage, notably Brian "Head" Welch (Korn), Bruno Major, and Paul Jackson (Blackberry Smoke).
