Using The StageBug™ SB-15 High Performance Signal Buffer

The Radial StageBug SB-15 has been designed to be plug & play easy to use. The following describes how to connect and get the most out of it. Feel free to download the manual by clicking on the icon at left.

Overview

The Radial StageBug SB-15 Tailbone is a combination voltage converter and buffer that enables the user to power any Tonebone pedal from two isolated 9VDC 200mA power supplies. It is designed to work with standard 9 volt 'center-negative' pedal power supplies that feature multiple power outputs. The SB-15 Tailbone also features a built in instrument buffer with DRAG™ control.



Using the voltage converter

Before making connections, it is good practice to turn your amp's volume down to ensure loud transients are not passed on to sensitive loudspeakers. Like the majority of guitar pedals, the SB-15 uses standard 2.1mm barrel jacks for the DC connections. Connect two DC cables from your power brick to the SB-15's IN-1 & IN-2 jacks. Next, connect a DC cable from the 15 volt OUT jack to your Tonebone pedal and you're set to go.



Using the instrument buffer

When driving very long cables or a chain of true bypass effect pedals, you may notice your guitar sounds dull compared to a straight connection to your amp with a short cable. This high frequency loss is caused by high

Insert the SB-15 buffer using standard ¼" cables. Placing it ahead of these loads will restore the clarity and impact of your instrument for a much more natural tone.




Using The Drag™ Control

Radial's Drag™ load correction allows you to dial in just the right amount of loading for your pickups to create the same impedance relationship as when plugging directly into your amplifier. Start with the Drag™ control set to the 12 o'clock position. Turning it clockwise will darken the tone while turning it counter-clockwise will brighten it. Strum a chord and slowly turn the Drag™ control until the tone sounds right to you. Use your guitar pick like a screwdriver to easily adjust the recessed control.
