How to change Marshall JMD presets from a BOSS GT-10 and what is possible to doYou can recall the tone presets of a Marshall JMD series amplifier from a BOSS GT-10 guitar effects pedal via a MIDI connection.In brief, when you select a patch on the GT-10 you select even a tone preset on the JMD amplifier, changing with a simple foot pressure both the guitar effects and the amplifier settings. But what is possible to do depends on the MIDI features of both devices.Let’s analyze the JMD amplifier for first.
Everything you need to know about its MIDI features is written into paragraph “ MIDI” at page 13 of its owners manual, and its architecture is quite simple. It can store and recall 128 presets via Program Change Commands received from its MIDI In connector.
Photo credit: BOSS CorporationWhen a patch is selected, the GT-10 outputs from its MIDI Out connector Bank Select and Program Change messages containing the values of CC#0, CC#32 and Program Number showed in the table on the left. But the JMD amplifier listens only to Program Change messages, and the GT-10 sends these messages containing Program Numbers from 1 to 100 that are repeated inside the groups named A, B, C and D in the table.

To store it, press the Footswitch / MIDI program switch (7) on the front panel twice. Its LED will flash until a valid MIDI Program Change Message is received, meaning that the amplifier is waiting for receiving the Program Change Message that will command the storage of the current settings into the preset associated to the Program Number contained into the message (see paragraph “ MIDI” at page 13 of amplifier’s owners manual).If you want to exit this mode without waiting for a command, press the Footswitch / MIDI program again. ( 3 ) On the GT-10 select the patch that you want to associate to the current amplifier’s regulations. The amplifier’s Footswitch / MIDI program switch LED (7) on the front panel should stop flashing, meaning that its has stored the current settings in the preset corresponding to the Program Number contained into the Program Change Message received from GT-10.
Each time that you select this patch on the BOSS GT-10, you will recall even this specific preset on the Marshall JMD amplifier.Related articlesShopping corner.
