Pick Up The Load Correction Device That Sounds So Good, You Will Use It On Everything - The Radial Tonebone Dragster Load Correction Device

The Radial Dragster is a super-compact load correction device that lets you adjust the load on your electric guitar pickup to replicate the sound as if connected directly to a tube guitar amp.

When a guitar is connected to a guitar amplifier, the pickup and the amp join together to form a circuit. But as soon as you introduce a buffer in between the pickup and the amplifier, the natural relationship is lost. The pickup only 'sees' the buffer and the tone changes. This is the fundamental reason why guitarists hate the sound of wireless systems and non-true-bypass pedals. The Dragster solves the problem by restoring the full rich tone you lose when you plug your guitar into a wireless transmitter or other types of buffered inputs such as effects pedals, mixing consoles, sound cards or all-in-one recording systems.

The Dragster is plug & play easy to use. You simply connect your guitar or bass to the Dragster using one of the ¼" inputs and then exit the Dragster using the other. Set the thumb wheel to the sound you like and you are set to go! The compact design makes it easy to fit on any pedalboard while the built-in mounting flanges make it a breeze to attach to a guitar strap. And its unobtrusive size and light weight won't slow you down. Few guitar accessories offer the tremendous 'bang-for-the buck' of a Dragster.


  • Many guitarists prefer to bypass all pedals when they are not in use. This 'true-bypass' approach basically means that all of the electronics are removed from the circuit – as if the guitar is connected directly to the amp. This has the benefit of a clean signal path, but tends to introduce switching noise when used with high gain amps. The Elevator gives you the choice by setting the 3-position baseline switch to the left – TRUE BYPASS position.


  • A signal buffer is basically a unity gain amplifier that is designed to lower the impedance and amplify the signal so that you can run longer cables without noise. High impedance (non-buffered) signals are more susceptible to radio frequency and magnetic field contamination caused by power supplies, transformers and light dimmers. This generally limits the cable distance to about 8 meters (25'). Lowering the impedance and buffering the signal will typically allow 16 meter (50') runs without noise when using good quality coaxial cables. Setting the 3 position switch in the middle position activates the unity gain buffer (no amplification).


  • Many guitarists do not like the sound of a buffer. This is because most buffers are designed using ICs and tend to load the pickup with a very high 1 meg-ohm impedance. This causes the guitar to sound glassy. Drag Control load correction allows you to dial in the load to replicate the sound of the guitar connecting directly to an amp with an 8 meter (25') cable. Simply set to 12 o'clock and adjust to taste. Rotating clockwise will sound brighter.


  • For those that want t push their amps a little harder, setting the 3-position switch to the right activates a boost circuit. This can be adjusted by turning the recessed baseline DRIVE control clockwise for more boost. This control is recessed (set & forget) so that it will not be disturbed once set. Adding this extra drive to your signal chain will push the front end of your amp harder and add a bit more punch to your tone.


  • Using the footswitch will activate the power booster. This can deliver as much as 18dB of gain for added loudness, sustain and distortion, depending on how your amp is set. Rotating the control clockwise increases the boost. For clean amps, you will get a clean boost. For slightly dirty amps, you will increase the level, add distortion and sustain. For amps that are already saturated with distortion you will increase sustain. Adjust to suit.


  • The power boost circuit is equipped with a 3-position MID BOOST switch that lets you increase the mid-range content in the signal. Keep in mind that guitars live in the mid range. By boosting the mids, you will increase sustain and increase your presence in the mix. This can be particularly useful with single coil pickups that are not as fat sounding as their humbucker counterparts. Left is off, middle adds a bit of mid, to the right – you get lots!
