Andy,
What caps / freqs did you use for your 6 position switches? What are you finding the most useful for different applications?
I am an amateur with recording so any insight is appreciated...

Hi,



  in bass, 330nF, 220nF, 150nF, 100nF, 68nF, and 47nF, giving 19Hz, 28Hz, 40Hz, 60Hz, 85Hz and 120Hz.

  in Treble, 47nF, 33nF, 22nF, 15nF, 10nF and 6.8nF, giving 4k1, 5k9, 8k8, 12k7, 18k9, and27k3


   I am using 28Hz and 18k9 quite a lot. I am using them across drum sub-bus post comp, mix bus duties, and especially on vocals.  They are awesome an individual drums too! Kick, Snare and toms - yum!  wish I had not come up/down so much, but had more choice at the extremes really. I wish I had 22k7 especially! I will be doing this on my next pair. I used Wimas for what it's worth. Available at Maplins!

  I would recommend NOT doing what I did if you want something general. The mid band would be extremely useful, and I would be very happy with say, bass set at 28Hz, and treble at 18k9. If you follow Audiox's front panel, and have 3 or even just 2 different frequencies top and bottom, you would be very happy, I am sure.

    I can recommend using API 2520 for this. It definitely adds a certain je ne sais quois . . . I am looking forward to trying the OA10 too! If you want to just use an NE5534, this sounds great too!, but a bit more brittle at extreme gain in the HF.



   Good luck! this is a very simple build, no power supply required if you have an API lunchbox, so very much safer too. It is not rocket science, and you will instantly love them ,i promise!


   Good luck,


    ANdyp

Cool! thanks for the advice.
I'll would like to keep the midband, and try to add selector switches for the high and low frequencies.
So maybe...
high: 12nf (15.8kHz), 10nf (18.9 kHz), 8.2nf(22.7kHz)
low: 220nf (28Hz), 100nf (60Hz), 47nf (120 Hz)

(edited to correct typo...)

So I kind of want to do a narrow/wide switch for the middle band. From my understanding it would just be a switch and a resistor but does anyone have an idea as to where I would want to place this? thanks a lot guys.

My next one:

- changed front panel design
- added LED for EQ in



The OPAmps are not final, ignore the violet wire.







Front panel made by Frank Röllen/NRG Recording.

Does anyone know a good source for cool looking small knobs, especially for the 4mm shaft pots?

I just finished my 169 using ne5534s throughout. What a simple, affordable and great-sounding project--thanks Audiox and Gustav!
Now, if only some enterprising individual were to jump in and start selling cheap and simple front panels...
