Copper Gear M.A.D.Box - Multisonous Amalgamation Device


This one has been a long time coming. A little over 5 years now. It all started back in 2005 when I was working at a club in Deep Ellum in Dallas, Texas. I spent hours talking with guitarists and bassists before and after their sets. Picking their brains about what they wanted in a piece of guitar hardware that didn't exist. All of that has led me to this unique piece of hardware.

The Multisonous Amalgamation Device aka. M.A.D. Box. It is by far the most ambitious device I have ever made. Enjoy.

CopperGear is proud to present the M.A.D. Box. The Multisonous Amalgamation Device. A unique handmade tube based guitar pedal mixer. Never before has a guitarist had such control over their sound, be it on stage or in your garage.

Simply plugin your guitar and up to six pedals into the M.A.D. Box then plug it into your amp or recording device and enjoy the freedom to mix, overlay, or layer to your hearts content. You will never need to record the same guitar track multiple times with different effects again. Side chain your pedals or mix down separate pedals independently. Layer your sounds like never before in realtime. Perfect for live gigs.

For example: use one pedal to create a solid distortion and send it to the mix, now setup a delay pedal to echo your clean guitar tone and side chain it to a flanger then mix it all down. The possibilities to fiddle around with are endless. ;)

With the tube, a 12AU7, being utilized as a pre amp and output stage amplifier you can get amazing warmth from your guitar. Use the pre amp stage to drive your pedals harder or even starve them to customize your sound even further. Even a 70's era signle coil pickup can sound like a powerhouse. The internal transistor based mixer is exceptionally quiet so all you hear is what you create.

Each channel from the bottom up consists of:

  • a pedal input and output (2 x nickle plated 1/4 inch jack)
  • a side chain input and output (2 x nickle plated 1/4 inch jack)
  • an input toggle (to change input from either main guitar or side chain)
  • an output toggle (to change output from pedal to side chain)
  • and a channel volume control so you don't have to affect the drive on some pedals by changing volume on the pedal.

Main controls are:

  • main input and output for connecting guitar and amp/recording device (2 x nickle plated 1/4 inch jack)
  • input volume controls the pre amp volume of the guitar signal
  • output volume controls the overall output volume of the device

CopperGear strives to blend the old with the new, and the M.A.D. Box is no exception. We have taken great pains to re-create old style circuitry and sound by not using any IC's (integrated circuits) in the audio path. And just like old synthesizers and telephone switch boards we have used the tactile experience of 1/4in TS jumper cables for side chaining different channels together. And, in sticking to tradition, there is no injection molded plastic to be found. The entire device is handmade from wood, copper, brass, and steel to hopefully bring you decades of dependable operation.

The M.A.D. Box is a culmination from years of suggestions, wishes, and dreams of hundreds of guitarists.
