DISC Radial Workhorse TankDriver Balanced Spring Reverb Interface

Full Description

Potential Applications

• Spring Reverb From A Broken Amplifier: If you happen to own an old guitar amp that is equipped with a spring reverb tank but the amp itself doesn't work, the TankDriver can help. Simply remove the reverb tank from the amp and connect the send and receive jacks to the input and output of the tank (most tanks are clearly marked to distinguish between the input and the output sockets)
• Spring Reverb From A Fender Twin: Simply disconnect the two RCA connectors going to the spring reverb and connect the TankDriver to the tank. Different amplifiers generally use different tank designs. Smaller tanks will have a shorter decay
• Stereo Set-Up: Take a pre-recorded stereo track and send it through two TankDrivers. This retains the full stereo effect and lets you alter the reverb tank to create unique spatial effects

Features

• 500 Series module that enables you to drive a balanced line-level signal through a guitar amplifier reverb tank
• Add unique spring reverb effects to your recordings
• Optimized drive circuit for low noise
• Transformer-coupled output driver with normal and high settings for new and old spring reverbs alike
• Separate drive and return controls for signal optimization
• Two tone controls for adjusting high-end shimmer and low-frequency boom
• Less noise and wider bandwidth from your spring reverb tank
• Can be used with a wide variety of sound sources
• Works with all spring reverb tanks with an input impedance of 600 Ohms of greater (lower impedance will result in a signal that is far too low to be usable)
• Full-size through-hole 100 percent discrete electronics for optimal signal transfer
• All components are hand-selected
• Road-proven Radial push switches with extra-durable metal outer casings, rated at over 20,000 cycles
• Incredibly robust double-layer steel front panel
• Dual potentiometers with double-up solder points for greater durability
• Potentiometers feature steel casings, steel shafts, and steel retention nuts
• Transformer-isolated design eliminates hum and buzz caused by ground loops
• Gold-plated 15-pin card edge with a double-sided design ensures a positive connection to the receptacle for improved mating
• Military-spec circuit board with double-sided design and a full ground plane that assures the lowest possible noise

Controls & Connectivity

• Blend: Sets the balance between the dry signal and the wet reverb
• Drive: Increases the output going to the reverb for less sensitive input circuits
• Omni Insert: Sends the signal to the Imniport TRS on the Workhorse which in this case is a send and receive insert jack
• Shimmer: Increases the high frequency tone of the wet reverb circuit
• Boom: Increases the low frequency tone of the wet reverb circuit
• Send: Output connection that goes to the reverb tank
• Recv: Return path from the reverb tank to the TankDriver
• Omniport: TRS insert jack with tip-send, ring-return. Only on Workhorse
