Brand new, old stock ZVEX hand painted Box Of Rock from 2008.

The Box of Rock 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. Look out when boosting what-not. 8^)

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メs output) into the right hand input jack. Plug the output into an amp or other effectメ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.

Note: We have a couple of these brand new old stock ZVEX Box of Rock, so serial number may be different than in pics.

Terrific addition to your backpacking gear
I like this map holder for its versatility in holding different size maps. Once sealed, it was very effective at keeping moisture out and protecting the maps. I originally used this on a 13K mountain ascent. Worked great. The only thing that can be tricky at times is sealing the top. It's not as easy as sealing a typical zip-loc kitchen bag, takes some doing to get it to seal.

Best Map Case Ever!!!
Size: Regular - 12 x 16 Inches
Best Map case in the market! Field tested and keeps everything dry. The size is fantastic and you can run paracord through the rings. I would recommend this to anyone that uses a map. You definitely pay for what you get and that's high quality and functionality.
