I own and love the Eden Navigator. I bought mine new last year and run it with a 1400 w power amp bridged mono inot an SVT810E cab. Its amazing! i set the pre amp dead flat and then just bump the mids about 2 clicks on the knob and its total nirvana!
The Navigator has a lot of features that you may or may not use, but it doesn't matter because the tone is fantastic. Very punchy and warm at the same time.
The footswitch that comes with it is a great unit as well. It has a mute to tune footswitch, volume boost, and then bypass for the enhancer and compressor.
Oh and the compressor is very very good! So even though the pre amp takes two rack spaces, you dont need a comp. I cant recommend them enough! You can buy a Nav and a power amp for less than one of the bigger Eden heads.
Dwelling on the banks of the deep end.
