If your preamp/amp has inserts, or a tape loop/monitor arrangement, the ideal method to give you sound shaping flexibility is to employ a top flight studio eq unit...
This will in 99% of cases provide a far higher fidelity and configurable/defeatable option than any internal circuit.
Manley make a couple of superb units, as do NEVE, and GML amongst many others, there are also numerous superb tube based mastering quality eq's, some active, some passive (i.e: no boosting, only cutting) which may prove equally effective or moreso !
Funny how some people 'can' the concept of EQ, when in fact most cables, speakers, etc... are all 'voiced' far from neutral by the designer !
More often than not the biggest EQ which many people are in denial of is their listening room/speaker interaction, so instead of treating the cause, they spend money in all the wrong places...'audiophiles' I think they call themselves, when in fact they have never taken time to study rudimentary acoustics theory, and understand very little about the actual recording or reproducing process.
All of that is fine of course, one doesn't need to be a Cordon Bleu chef to appreciate fine food, however more money often equates to less cents ;-)
