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

Good book
Format: Paperback
This is amazing book. So far it's the best finance book I've ever read. I would give it 5 stars but the delivery services was bad for 2 reasons: the book had not protection and the worker did not notify me when leaving the product at home.

Only for real men...
Style: Rough Exfoliation
So much crying here. This is not a luxurious sponge. But if your are a man, this is the hot ticket. Coarse but not like a cheese grater. Holds liquid soap well. Foams well. The elastic strap let's you keep hold of it easily and will reverse over the pad so you can use either side. Leaves your skin pink and fresh... in a manly sort of way. 😉

SELF TANNERS MUST HAVE!!
Style: Rough Exfoliation
This product is perfect for those of us who use self tanners!! For self tanners to work well and not look splotchy one needs well exfoliated skin and this sponge is exactly the right tool for the task! My skin feels so much softer, my self tanner working much better and my body lotion seems to absorb more quickly. These sponges are easy to hold and have a loop to hang from while they dry. Every week when I wash my towels I toss the sponge(s) into a lingerie bag and wash with the towels. I always hang to dry so no idea how they’d handle a dryer. I will never be without these sponges!

If you like it rough (enough)...
Style: Rough Exfoliation
Perhaps a tad rough for some, the Caveem scrubbers are ideal for me- rough, but not cheese-grater-aggressive. I have been using the first of my two pack for almost three months and, beyond a slight "softening" of the surface, it is in perfect shape- no deformation, no open seams, no tears, thin spots, or defects of any kind. It looks and works like near-new. The sponge is a great size for man hands- basically 6" x 4", and is thick enough to hold ample soap and water to cover quite a bit of skin without reloading. The strap is comfortable and sturdy and, perhaps trivial, but the colors are manly without branding with skulls or wrenches or some other compensatory masculine iconography! I am very satisfied and if they ever wear out, I will happily purchase again.
