The Box of Rock (TM) is Z.Vex Effect's first "distortion" pedal, highly specialized to simulate the "everything on 10" sound of a classic Marshall JTM45 non-master-volume amplifier. You may use the Box of Rock effectively with many different amplifiers, but to get the sound I heard when I designed it, try it through a Marshall at least once. You may use your guitar's volume control to adjust for the exact amount of distortion you need, all the way down to very clean and clear with most drive settings. You will notice the words "distortron engine" on the Vexter version of this pedal (no, that's not a misprint) on the pedal. This is what I named my distortion circuit... call me crazy. On the hand-painted version, the stomp switch on the right is labeled "ROCK" instead, because our paint brushes are too wide for so many small letters.

The Box of Rock also contains an extremely high-headroom, unity-to-50X gain booster with nominal input impedance and low hiss. It is very similar to the SHO boost circuit, with refinements to make it sound more like a standard amp input and less glassy. The boost channel can be used alone or in conjunction with the "distortron engine" channel. The boost channel follows the distortion channel so that the distortion is able to hit your amp harder (at a higher volume) when both switches are engaged, for boosting solos and what-not.

The Controls:
Drive: Sets the amount of distortion. Start around 1:00 o'clock.
Tone: Adjust for treble content. Start around 2:00 o'clock.
Vol: Adjust for distortron engine volume level. Start around 9:00 o'clock.
Boost: Sets the boost level, which is engaged with the left stomp switch. Start around 11:00 o'clock.

The Drive and Boost controls are based on my original Super Hard-On gain control, so they may crackle when turned. This is perfectly normal.

Operation:
Plug your guitar (or any effect's output) into the right hand input jack. Plug the output into an amp or other effect's input. Rock out. Careful with the Boost setting when using a high-powered amp with lots of headroom... you may be shocked at how loud it can get!

The best way to complete this pedal is to run it through a Marshall amplifier on a warm clean setting (try strapping the channels, setting the volumes below 3, and setting all other controls to 6 as a start point), which has the proper voicing to reveal the "rock" in the Box of Rock.

Battery Change:
If the performance of your pedal seems diminished or the LEDs become very dim, it's time to change your battery. Remove the four screws on the bottom of the pedal and carefully remove and replace the old battery, putting it back exactly in the center of the pedal on edge so that it is gripped tightly by the lid when it is screwed back in place.

Specifications:
Uses 1 9V battery (preferably alkaline, but the unit is shipped with a carbon-zinc battery.) The low current operation of this pedal's circuit will give you a long battery life. Current draw is approximately 3mA. A DC power jack (standard Boss configuration with center negative) is provided on the side of the pedal. Use a high- quality 9V adaptor for all high-gain effects!

Warranty:
All hand painted Z.Vex pedals have a lifetime warranty.

- Our international shipping rates should reflect on the item listing. Feel free to message us directly for shipping quotes on specific items or with any questions. Please note, international shipments may take extra time and are subject to delays.

- All shipping rates are for actual transportation charges and do not include VAT, import taxes, or brokerage fees, which vary from country to country. We recommend planning for those fees in advance if possible.

- Most of our preset shipping rates are for USPS International Service. USPS is typically less expensive than UPS, but their international tracking system is not as accurate. Tracking updates are often infrequent. Packages mailed internationally with a Customs Declaration Label number beginning with an “L” or “U” are not traceable. These numbers are NOT for tracking purposes and will not be scanned by the destination country’s Postal Service. They are used for Customs and dispatch purposes only. In order to see end to end tracking of a First Class or Priority Mail International package of less than 4 lbs, customer will need to add the Registered Service, or use Global Express Guaranteed or Priority Express Mail services instead. These are the only mailing services that will give tracking information all the way from the acceptance date until the delivery date, unless the package is going to a “Non-scanning” country.

*Be advised, international packages  shipped USPS are often in transit a number of weeks, and   can be subject to delays. If you'd like to upgrade your shipping, please let us know before   placing your order.  

-We ship guitars via UPS Worldwide Expedited unless you request a different service. Arrival   times may vary from country to country. Some large items such as bass guitars, drum kits,   amplifiers, and speaker cabinets may not be eligible for shipping via USPS due to size   limitations. Some brands cannot be shipped internationally due to manufacturer restrictions.   Feel free to message or call us with any questions. - If you order contains Brazilian Rosewood, or any other CITES restricted woods, your   shipment might be delayed due to Customs processing standards that CME is subject to as   the shipper. All orders requiring CITES documentation must ship to the buyer's residential   address. If your country requires CITES import permits, please work with your local Customs   agency to obtain these permits prior to shipment. - We are unable to ship to Russia due to the current trade sanctions.
