Where's the GTR4000?

We no longer manufacture this product because the DSP7000 has all the features (and more!) of the GTR4000, and many more presets, including many of those in the GTR.  It also includes digital I/O and greater DSP power.  There are a few presets in the GTR4000 that don't come with the DSP7000.  If you feel you must have them, the GTR Guitar Preset Library remains available.  We strongly recommend considering the DSP7000 as an improved replacement.
