such a great idea. all valve twin channel modules. add this to the syn 30 Head and you have 3 channels. easy to sap the modules.
add in a syn2 and another module say the Diezel vh4, and you have a 5 tube, 4 channel all valve preamp.
the T/DLX offers really nice cleans on the blue channel reminding me of a Fender twin with a nice country twang, with the red channel giving the overdriven dirt combo sound. Adjust the 2 switches for even more tonal variation.
love min, and looking forward to adding more to the rig
