The Schiit Loki equalizer at $149 might be what you're looking for. Has a bypass for those times when you don't need equalization.

External EQ/other solution?
Hi, I have a Rogue Audio tube amp, which I love, a U-Turn turntable and an NAD phono preamp. Here's my issue: on some recordings, at a high volume, the bass can really drown out the rest of the record. But I have no way to adjust bass/treble etc. Can someone recommend a reasonably priced solution to this? An external EQ? Something else? Many thanks in advance!
