I had a question concerning parametric EQs. I've been thinking about adding one in my lineup for awhile now, but I have no idea what to look for. I've been considering a blackface Orban 642B for awhile because it combines my most important criteria: a combination of reasonably good quality and price. Problem is, I never see 'em turn up anywhere. They seem pretty appealing, plus being able to link the channels seems like a pretty big plus in terms of versatility. Are there any other sleeper deals out there? I mean, there must be more supply than demand when it comes to the used Parametric EQ market, right? Like how a few years ago you could get Sunn amps and Sound City amps for a pocket full of lint, y'know? Also, thought I intend on using it primarily on my Matamp to smooth out the edges so to speak, I was wondering how it would work on a Hiwatt DR103. I've never really screwed with rack gear much, so I don't know much about it. Would it flatten out to tone too much since it's a line level piece? I mean, old Hiwatts don't have a loop, so it would pretty much have to go in front of the amp, wouldn't it? Would that work? Also, if I tried boosting before it, would that mess up the signal as well?
