The Tonebone Twinline™ is a unique device that enables a guitarist to share effects pedals between two amps when using the amplifier's built-in (rear-panel) effects loops.

Consider the problem: Many guitarists prefer to use the effects loop in the amplifier to insert pedals into their signal chain. This is particularly useful with delay pedals where applying echo to the signal after the guitar amp's preamp distortion results in more distinctive notes and more pleasing sonic results. A problem arises when using two amps on stage: how do you toggle the pedalboard between the two amps? The guitar player must either duplicate his pedal setup (one for each amp) or completely change his setup by connecting the pedals to an AB switcher and then connect the pedals to the front panel inputs of the amps.

The Twinline can be thought of as a pedalboard switcher that lets you remotely toggle the effects from one amp's effects loop to the other, thus allowing the guitarist to share his pedalboard between the two amps. To accomplish this, the Twinline is equipped with two amplifier effects loop circuits – each with separate send and receive levels to optimize the signal path for each amp's effects loop. There is also a third effects loop for the pedalboard. This features a choice of unbalanced ¼" connectors for typical guitar pedals or balanced XLR connections for studio effects. A remote control input is used to toggle the active amplifier's effects loop via a contact closure using a MIDI system or latching footswitch. When used with the optional Radial JR2™ remote, this adds the ability to bypass the effects completely.

As with all Radial products, the Twinline is made from heavy duty 14 gauge steel for ultimate durability and maximum shielding against stray magnetic fields while the book-end design creates a protective zone around the controls and switches. Inside, 100% discrete class-A electronics deliver optimal sonics as it buffers the circuit while transformer isolation eliminates troublesome ground loops that can introduce hum and buzz if left unchecked.

The Radial Twinline brings forth a unique solution to a long standing problem.

  • Shares your pedalboard between two amp loops
  • Lets you optimise the signal path for each amp
  • Works with pedals or balanced studio processors
  • Can be remotely controlled using a footswitch
