It is a very smooth type of OD. It can go from nothing at all to sounding like a very warm vintage overdriven tube amp or a clean flat booster or a treble booster even a tweed amp.

With the treble boost all the way off, it is warmer than most tube amps. . . 

The Eternity Overdrive always stays true to what's coming out of your guitar so you never turn into the pedal. No matter how hard you drive it. It also breaks up the harder you dig into the strings, which is priceless.

The Silver Edition is designed to operate more quietly than previous editions.

Features
