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

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
