I played an eden CXC 210 the other day and I was impressed by the head! I really like the gain. However I may very well not be purchasing this amp (may go for GK 700RB 210 - for volume and transport features). I love the little gain button that is on the Eden WT-330 (time traveler). Is there any pedal or preamp that does this with the click of a button? I'm not looking for a grindy distortion or overdrive but I am looking a good growl and what I think is a good gain or boost, but that is only what I think it is (Am I right?).
