StompShare is a virtual effect shop app that recreates the effects display area of an instrument shop. This shop includes not only popular types of stomp box effects and rack mount effects, but it also offers guitar amp models and emulations of classic effects that can no longer be found new, for example. You can easily audition and even try effects before buying the ones that you like by connecting an MS-100BT hardware multistomp effector and an iOS device by Bluetooth. Then, you can add purchased effects to your MS-100BT and use them like any other hardware effect. We plan to continue adding even more variety of effects to StompShare in the future.

■Current StompShare provides 71 Effects and 23 Amps, total 94.
-For Bass
22 effects, 9 amps
-For Guitar
49 effects, 14 amps

■Connects easily using Bluetooth
-Use Bluetooth to connect the iOS device and the MS-100BT without cables.

■Zoom in and out on effects
-Double tap, pinch out and pinch in to zoom in and out.

■Select effects by category
-Effects are categorized so you can easily find the ones you want.
5 categories
-You can also choose to view just the newest releases or all the effects at once.

■Explanations for all effects
-An explanation for each effect includes information about the effect it models and the tones it can create.

■Audition demo sounds
-Listen to demo sounds of every effect in the shop.
-Turn the effect on and off while auditioning it.

■Effect trials
-Write the effect to an MS-100BT pedal and use it to adjust parameters as you try playing with it.
-You can also use the trial effect in combination with other effects already in your unit.

June 2017 Update (important info)


All add-ons in the StompShare App are NOW FREE! 116 modules include amps, distortions, modulation, compressors, synths, pitch shifters and more. The MS-100BT and the App are discontinued and no longer supported or updated.

If the app has problems, delete it and re-install. That may fix the problem, even if temporarily. It occasionally freezes with my 4th gen iPad, but has worked fine with an iPod Touch 6 (YMMV). NOTE that if you delete and re-install, it will force you to re-install all add-ons to your MS-100BT. So you may need to take notes about what you have installed.

I suggest making sure bluetooth pairing is finished & active before launching the app.

If you don't own a Multi-Stomp product, the app provides a great way to hear decent recordings of examples of the effects as well as try out the module for 15 min.

Navigating the "shelf" is clunky. Labels can be hard to read. Add-ons must be transfered one at a time. There is no list view or search function. There is a categories view.

The MS-100BT can't hold ALL the add-ons, but it can hold MOST of them. I was able to load 90 out of the 116. I might be able to load more, but I got everything that I wanted loaded.

Zoom did not include any info about how much processing each add-on requires, or how much memory it takes up in the pedal. That would have been helpful.

In addition to add-ons, the app will update the pedal's firmware if needed. It will also let you delete selected add-ons from the pedal. But it doesn't do any patch management/storage.

The MS-100BT is the only pedal in the Multi-Stomp series that includes all bass, guitar, and effects modules. All the other pedals omit some effect types. It is a shame that it is discontinued. It's a good pedal.

Holy S#!+ This Pedal Is Amazing!

It’s nice to see that a company actually puts in work to create the one and only holy pedal. Imma be honest and say it’s not that “Great” of a time on bass, but in guitar it’s awesome. I also wish that there were more updates. Good job Devs!
