Well, this is my first journey into the germanium/rangemaster clone territory. Just got it today so I am still on the honeymoon. Here it goes - So far I love this thing. It sounds perfect through the AC30 on the brink of breakup and makes my neck pick-up on the Les Paul (which has always sounded muddy) breathe a little. I threw it in front of the FDII and think I have found a great combination. I actually play my FDII with the volume comp/cut pulled up instead of my normal down position. I cannot believe the beautiful tones I get from the Germanium alone. It actually works with the volume on my pickups so I can dial my dirt/grit on the guitar and with my pick. PLUS - got it for $66 brand new on ebay Cannot beat that price. I wish I could record clips for everyone but I think my playing might spoil the pedal. All other Germanium Booster users -- welcome me to the club.
