I have owned many peramps and amps. I honestly dislike Eden as a company after my 2 problem incidents with them. BUT, the Eden Navigator is so much better than any other preamp I have ever played that I can't let myself go without it. The eq does anything I need it to, I can run any combination of bass/effects/vocals/loops through the thing AND it has a fantastic tube tone from smooth to growly. I just thought that we could compile some info about them. Even if you have had bad experiences lets here them. I enjoy the enhance for when I need to cut through, but rarely use it. The turbo boost is great for soft technique in a loud situation. The compressor of button is nice because I can turn the compressor on just for the heavy handed stuff but keep my sound otherwise. The tube knob is fantastic. I turn it about 10 oclock for "my tone" but move it around as needed. This alone makes it versital between generas. What do you think?
