Radial Tank Driver

Spring Reverb Interface


About this item



The Radial Tank Driver is a unique 500 series module that allows you to drive balanced line level signals through guitar amp reverb tanks, optimized to work with both modern and vintage spring reverb models.

  • Balanced interface for guitar spring reverbs
  • Use the spring reverb in your guitar amp for mixing
  • Add unique reverb effects to your recordings
  • Optimized drive circuit for low noise operation

Create unique tones with your existing spring reverb

With the Tank Driver, you can take any balanced line level signal or prerecorded track and play it through your favorite spring reverb. Think of it like a Reamp device for the reverb tank in your amplifier, allowing you to send vocals, drums, or any audio material through any spring reverb for a whole new palette of sonic options. The design begins with a transformer-coupled output driver with normal and high settings for new and old spring reverbs alike. Separate drive and return controls allow signal optimization to maximize signal to noise. To further tailor the tone, the Tank Driver is equipped with two-tone controls that let you adjust the high end (shimmer) as well as low-frequency content (boom).

The Radial Tank Driver is a unique interface that has been designed to work with most common spring reverbs. As such, the frequency response and tone shaping cannot be viewed in the same manner as one would a typical effect. The frequency response and drive network must be optimized to work within the confines of a spring reverb. Of note will be the high frequency Shimmer and low frequency boom control curves which allow the engineer to color the reverb to better fit the program material.
