We both sat down and put some thought into it, because I thought pre amp needed to be more flexible every soundman plays their sound different and have different boxes so I wanted something variable so you can use it with any box even home hi-fi

No formula sound had no input. This is a LIGWA & Charlie Destructor Production.

Unit looks good, I can see it appealing to a lot of people. At least it's not a plate full of Knobs. Good luck with it. I might have to find room for it in one of my Racks. ------------- http://www.facebook.com/tony.rossell.3" rel="nofollow - http://www.facebook.com/tony.rossell.3 |

Marjan & Co won't let you.. They believe only bearded cavemen with Scoops & other Stone age implements, use pre-amps. Would love to see one of them turn up in GP with 4x 1x18 Reflex, to face Scoop system with this 1U beast.  ------------- Global Depopulation - Alive and Killing. |

Charlie is a legend. His old school power amps and preamps still put more modern equipment to shame. I'm looking forward to see the 2u version. ------------- LET THE BASS ROLL LIKE THUNDER & THE TOPS LIKE LIGHTNING..... |
