Plug into the Box of Rock and enjoy amazing high gain distortion with clarity and punch. The Vertical Vexter Box of Rock is an amp in a box style distortion pedal designed to simulate the everything on 10 sound of a classic Marshall JTM45 non-master-volume amplifier. This version is vertically oriented to provide another option for making efficient use of pedal board space.
ZVEX Vertical Vexter Box of Rock Distortion Pedal Features
- 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.
- Volume: Adjust for distortion engine volume level. Start around 9:00 o’clock.
- Tone: Adjust for treble content. Start around 2:00 o’clock.
- Drive: Sets the amount of distortion. Start around 1:00 o’clock.
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 our 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 distortion 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.
Plug your guitar into the right hand input jack. Plug the output into an amp or other effect’s input. Rock out. Careful with the Boost setting, you may be shocked at how loud it can get! The best way to complete this pedal is to run it through a tube amplifier on a warm clean setting as a start point.
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, 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.
