Bob G Posted January 28, 2017 Share Posted January 28, 2017 I have this Peavey head dated 1979, I'm used to bass/mid/treble/maybe presence on amps, what does the parametric eq do, and how does it work? Quote Link to comment Share on other sites More sharing options...
BassBus Posted January 28, 2017 Share Posted January 28, 2017 Let's say your talking about mid frequency. You'll have a knob that allows you to select the frequency you want to control. Another knob will work alongside that to boost or cut that selected frequency. The boost and cut knob works in the same way as your regular bass/mid/treble knobs but you have the addition of being able to select which frequency you boost and cut.

BigRedX Posted January 28, 2017 Share Posted January 28, 2017 A good parametric EQ will also have a Q control which changes how wide the frequency range is. Quote Link to comment Share on other sites More sharing options...

Chienmortbb Posted February 3, 2017 Share Posted February 3, 2017 [quote name='Jus Lukin' timestamp='1485624273' post='3225430'] I [i]think [/i] having all three controls is parametric, just frequency and gain/level is called semi-parametric. Pedantic I know! All the info above is correct though, basically a sweepable freqency control. Additionally, with the setup you have you may find it cuts in a narrow band and boosts in a wider one although you'd have to check the spec for that specific amp. [/quote]Correct!
