The following page describes how to use the Loopbone in a typical setup. For more details, we invite you to download the complete manual by clicking the icon at left.


On quick view, the Loopbone is a very simple effects device controller designed to fit on the pedalboard and give the user control over two effects loops. The two effects loops are connected in series enabling the first set of pedals to feed the second set.

There is no power switch on the Loopbone. Connecting the Loopbone's power adapter turns the unit on. Plug in your guitar, amp and effects and you are pretty much set to go. The LEDs will indicate which of the two loops is active and if the power booster circuit is turned on. Always test at low volumes before turning up!

Taking a closer look

Following the block diagram from left to right shows you the actual signal flow. The guitar connects to the Loopbone where the signal is buffered to lower the impedance and reduce noise. The class-A buffer is accompanied by Drag Control load correction. This recessed 'set & forget' control lets you adjust the load on the pickup to replicate the tone and feel as if connected directly to a tube amplifier.

Right after the input buffer is a second buffer that feeds the tuner. This separately buffered output is always on, making it easy to quickly adjust the tuning on your guitar at anytime. The buffer also stops any of the clocking noise or unwanted loading that your tuner could introduce.

Then come the two loops: each loop is equipped with separate ¼" send & return jacks to connect to your pedal chains. There is also an LED indicator for each loop, letting you know when a loop is on. (A contact from the switch also serves to drive the Slingshot remote control.) Once the signal is processed by the two loops, it then passes through the power booster. This built-in variable booster lets you increase the output for soloing. Simply adjust the desired gain boost via the recessed 'set & forget' control on the back side.

Using the Loopbone

With two loops, you can set up the Loopbone to suit your particular playing style and personality. For instance, you can set up Loop-1 with all of your distortion and fuzz pedals and then set up Loop-2 with your delay, reverb, chorus and other time based effects. This way you can combine all of your effects by type and change the setup to suit the moment. Alternately, you could create two 'presets' whereby in Loop-1 you have a couple of distortion pedals, a phase shifter and a delay while Loop-2 could be arranged with a fuzz, flanger and reverb. This way, you could prepare the sound before it is needed and have all of the effects turn on with a single foot stomp. Experiment using the Loopbone with various setups and you will quickly come to find the best one for your particular style.

The built-in power booster

One of the cool extras built into the Loopbone is the Radial power booster. This class-A boost circuit is situated after the two loops and is arranged to give you tons of extra output for soloing. Simply adjust the 'set & forget' booster control using a guitar pick, and stomp when rocket fuel is required!

Adding Slingshot to your setup

A powerful feature built into the Loopbone is the Slingshot remote control. This ¼" jack enables you to send a contact closure command to another device such as a guitar amp so that it changes modes at the same time as you turn on a loop. You could for instance turn on loop-1 with a chorus and a delay and have your amp change channels to an overdrive lead tone at the same time. This yields the same type of professional stage switching that is usually only made possible with a high-end custom switcher.

The Slingshot output can be configured to work with older guitar amps using a standard contact closure or be set with a pulse to work with today's electronic switching systems. You can also use the Slingshot to turn on a multi-effects processor or connect it to another Slingshot equipped pedal like the Headbone or Cabbone and have it automatically switch heads or cabinets when you select a loop. A top mounted 3-position switch lets you assign the Slingshot to work on either Loop-1, Loop-2 or both and is compatible with both standard ¼" and TRS type cable connections.
