The Radial Engineering Tonebone AC Driver is a studio-quality preamp in a pedal form factor. It's designed to amplify acoustic instruments on the stage, employing a Class-A buffered circuit for pristine audio. To help you achieve the tonal profile you're looking for, a low-cut filter, a notch filter, and a level knob are all supplied, as is a 180° phase switch to bust feedback.

   

The footswitch mutes the pedal so you can tune quietly on stage, provided you feed your signal to a dedicated tuner by means of the dedicated 1/4" tuner output. In addition to the tuner output, a 1/4" instrument output for acoustic amplifiers is on hand, as is an XLR output with a dedicated ground-lift switch for the house PA. Heavy duty components are used throughout to ensure the pedal's durability. The pedal requires a separately-available 9 VDC power supply.


Controls at a Glance

  • Notch Knob: Sets the center frequency for the notch filter, which is used to eliminate feedback
  • Low Cut Knob: Variable filter that rolls off low frequencies and controls bass resonance
  • Level Knob: Controls the output of both the XLR and 1/4" outputs
  • Notch Q Switch: 3-position switch bypasses the notch filter or selects between regular or deep notches; this control works in conjunction with the notch-frequency knob
  • 180° Phase Reverse Switch: Reduces onstage feedback by reversing the polarity of the XLR output
  • Mute Switch and LED: Footswitch turns off all outputs except the tuner output, and can help with silent tuning on stage


I/O

  • A 1/4" input accepts your acoustic guitar's signal, and you can route to a 1/4" output and a balanced XLR connection for the house; a 1/4" tuner output transmit dry signal regardless of the footswitch position
  • Durability Features
  • Switches with metal outer casing are rated at over 20,000 cycles for durability
  • Glass-filled nylon XLR connector with large nickel-silver pin contacts are tougher than steel
  • A double-sided military spec circuit board has been employed to ensure durability, providing a full ground plane to reduce radio frequency interference
  • An I-Beam 14-gauge chassis prevents the circuit board from being torqued

Quality is very nice at a good price
These are my go to paper plates. The are just the right thickness for our use. You can't beat Dixie plates. I am a repeat buyer. A little expensive but worth it to me.

DURABLE, GREAT QUALITY
I ordered these plates for a family reunion. The quality is great! Stood up to plates full of spaghetti, various bbq meats and veggies, potato salad and more. No Accidents caused by structural failure of these plates. Pricing is actually better that the grocery store brands AND there are more plates in a package. These will be my go-to plates for all of my entertainment needs going forward.
