I'm looking to beef up the sound of various outboard synths (analog & digital) with some distortion, helping them to cut through a mix. I've played with various digital effects/plugin distortions such as Izotope Trash (not too bad), TC Fireworx, Ensoniq DP4+, etc., but haven't been terribly impressed with any of them.
I've also tried overdriving various analog hardware like: JoeMeek pre's, crappy Mackie pre's, Moogerfooger pedals (OK for some stuff, but can be a little too creamy for other stuff - like leads), Frostwave Resonator (does the trick once in a while).
What good distortion has anyone used for this purpose? I'm not looking to break the bank, but flexibility and the ability to attain an aggresive sound, while retaining the some definition/character of the original are key factors.
Any thoughts or ideas?
