I'm looking for a rackmount (or other format) eq like Garageband's or other DAW eq that has at least the following: - [most important] High and Low pass filters, up to -36 or -48db/octave and adjustable q/resonance - five bands of fully parametric eq, with adjustable frequencies, Q, and gain - xlr in and out that doesn't add much distortion (generally higher quality). Treble and bass shelving controls would also be cool, both with control over corner frequency, +/- gain, and q control. It'd be nice to also have xlr in and out. Ideally, under $500. Anything like this out there? Can be digital, rackmount, or any other physical format. Is there something like this? I would be using this as a user-created cab sim of sorts, installed between my preamp and power amp.
