DT Customizer was written to allow owners of Line 6 DT 50 and DT25 amps take advantage of the exciting capabilities provided with the 2.0 version of the amp firmware.

There are two seperate DT Customizer applications. There is one for Mac OS simply called DT Customizer (currently in beta testing), and there is an iOS application (Version 2.0 supports both iPhone and iPad) called DT Customizer ToGo. Both DT Customizer applications allow users to modify and save DT amp voicing configurations to settings files stored on your computer or iOS device.

These setting files can be shared between the two platform specific applications. However, the Mac app does not currently support some more recent features, such as voicing names. So, be careful using the beta Mac app on settings files created with the iOS app, because you will lose some features if you save the settings files with the beta Mac app.

The iPhone/iPad version is available in the Apple App Store.

In order to communicate between an iOS device and a DT-Series amplifier, a MIDI interface (such as Line 6 MIDI Mobilizer II, or iRig MIDI Interface) is required. This interface must support the Core MIDI API. So, the first version of MIDI Mobilizer is not supported by the app.

The Mac version is now in beta test, and is available to download and try out for free. But, if you do find it useful, and you want to help keep improvements coming, please consider a donation. Just click the "Donate" button on the right side of the page and contribute any amount. Thanks.

DT-Series Amplifiers

The Line 6 DT50 and DT25 amplifier lines offer beautiful, classic tones. Classic American clean, chimey and crunchy English tones, modern high-gain distortion and much more.

DT-series amplifiers combine the analog components found in most vintage and modern tube amps with programmable control, giving you a complete boutique amp factory in one convenient package.

In order to take advantage of this flexibility, you must first have the 2.0 Firmware update for DT25 and DT50 installed on your amp. The firmware update lets you create original amp tones by pairing your choice of 30 HD preamps with any combination of dynamic topologies (negative feedback loop, operating class, power tube mode and more) within Reinhold Bogner’s reconfigurable tube power amp.
