Casio Dimension Shifter Review: Front or Back Mounting, What Works

Introduction

The Casio Dimension Shifter is an expression controller system that mounts between your guitar strap and the guitar body. It lets you control effects pedals and other gear by moving the guitar itself, rather than using a traditional foot pedal. The system includes a receiver that sits on your pedal board, and it can be paired with compatible pedals to create expressive, hands-free control while you play.

One question keeps coming up from guitarists who are interested in this system: can you mount it at the back of the guitar instead of the front? Many players want to show off their full strap without a piece of technology interrupting the look. This review answers that question directly, with hands-on testing of both mounting positions.

What the Casio Dimension Shifter Does

The Dimension Shifter mounts between your strap and your guitar. The receiver connects to your pedal board, and you can use it to control pedals that accept expression input. For example, it works with pedals like the Bliss Automatone Preamp Mark II, which automatically moves its sliders as you express yourself through the guitar movement.

The system is designed to make playing more dynamic and visual. Instead of reaching for a foot pedal, you can shape your sound by tilting or moving the guitar. This makes it especially appealing for live performances, video demos, and any situation where you want to keep your hands on the instrument and your focus on the music.

It is worth noting that this system is not inexpensive. It is an investment, but for players who value expressive control and a more engaging performance style, it can be a lot of fun to use.

Who This Product Is For

The Casio Dimension Shifter is best suited for guitarists who already use expression-capable pedals and want a more intuitive, visual way to control them. It is particularly useful for players who record video demos or perform live, because it eliminates the need for an extra camera angle to capture foot pedal movements.

It is also a good fit for players who want to add a theatrical element to their performances. The ability to shape your sound by moving the guitar itself can be striking on stage, and it opens up creative possibilities that a traditional foot pedal cannot match.

Mounting It in the Back: The Real Test

The main question this review set out to answer is whether the Dimension Shifter works when mounted at the back of the guitar, between the strap and the rear strap button. The short answer is yes, it does work, but there are important trade-offs to understand.

When mounted at the front, the system is easy to control because your picking hand naturally rests near the guitar body. You can apply pressure to the body or bridge to tilt the guitar and shape your expression. At the back, however, the guitar interacts with the device differently. Your playing hand is not applying pressure to the guitar body in the same way, so you may need to grip the bridge or move your hand to the body to express yourself effectively.

In practice, rear mounting is not as immediately usable as front mounting. It takes more deliberate effort to control the expression, and the response feels less natural. That said, it is still possible to use it effectively, especially for momentary bursts of expression during a performance.

Using It in the Back: Expressiveness and Control

When you mount the Dimension Shifter at the back, you lose some of the expressiveness you get from the front position. The movement is less intuitive, and you have to think more about how you are tilting the guitar. However, it is still a viable option if you want to keep the front of your guitar clean and show off your strap.

For stage performances, rear mounting can actually be theatrically fun. If an audience sees a guitarist expressing themselves by moving the guitar in an unusual way, it can be a memorable moment. The element of surprise adds to the performance, even if the control is not as precise as front mounting.

One practical suggestion is to buy two units and mount one at each end of the guitar. This gives you the option to use the front position for precise control and the rear position for those moments when you want to hide the technology and let the strap shine.

The Jumping Test: Front vs Back

To test how well the system holds up during energetic playing, a jumping test was performed with a heavier guitar. The front-mounted position was tested first, and it performed as expected, keeping the guitar stable and the expression control responsive.

Then the same test was repeated with the system mounted at the back. The results were similar in terms of stability, but the control was less precise. The guitar moved more freely, and it was harder to maintain consistent expression while jumping. Still, the system stayed in place and continued to function, which is reassuring for players who move around a lot on stage.

Buying Advice

If you are considering the Casio Dimension Shifter, the key decision is where you want to mount it. Front mounting offers the best expressiveness and ease of use, making it the recommended position for most players. Rear mounting is a valid alternative if you want to keep the front of your guitar clean, but you should expect a learning curve and slightly less precise control.

For players who want the best of both worlds, purchasing two units is a practical option. This allows you to switch between front and rear positions depending on the song, the performance, or your mood. It is a more expensive approach, but it maximizes the flexibility of the system.

Conclusion

The Casio Dimension Shifter is a fun and expressive tool for guitarists who want to control their pedals without a foot pedal. It works well in the front position, and while rear mounting is less precise, it is still a viable option for players who want to show off their strap or add a theatrical element to their performances. The system is not cheap, but for the right player, it can be a worthwhile investment that makes playing more dynamic and engaging.
