This is probably not what you want to hear...but I got my money back. All of the Electrix stuff is set up for +4 operation. Most Instruments are around -20. You would have to set up your entire rig for +4 using a Console with Aux sends at +4. It makes it a REAL hassle if you want to run into an Amp. I still found it to be noisy on my Yamaha ProMix 01v. I don't get ANY noise from my other Filters (Electro Harmonix, BigBriar, Mutron etc....) but they are made for Instrument level Operation, and NOT DJ gear. I really like the fetaures in the WHOLE ELectrix line, but they really need to 'fix' this if they want to sell to Guitar Players. jmp In a message dated 4/9/01 11:22:33 AM, Loopers-Delightemail@example.com writes: >So on a whim I ordered an Electrix FilterQueen and now I have a quick >question for anyone who has one of these.
