Title: Looking for a quiet EQ project.
Post by: blearyeyes on February 17, 2018, 06:18:11 PM
Do you know of a good EQ project?
Prefer not to deal with Vero but I could if push comes to shove.

I have a Bugera and a VOX AC15HW. Really night and day tone wise.
Would love the option to EQ/tune differing pedal combinations.

Should sell both amps and my car and buy a Matchless or something spectacular.

Having an audio engineering background I love me my EQz..
I bought a BOSS 7 band pedal in the early 80s and it was really noisy. Couldn't use it so I'm gun shy in that department.

I'm working on something, but don't know about the noise floor yet. Maybe try the parametric EQ from BYOC? possibly with fixed Qs so save some space and knobs. I've been fiddling around with semi-parametrics and I think they're less prone to noise than graphic EQs and in reality more flexible.

I have built the eq from 1776 effects the six shooter I believe. 6 frequencies.  It is pretty quiet until you really start diming the high frequencies. Really easy build.

If an EQ is noisy, try running a booster before it.

YMMV obviously, but if the incoming signal is at a hotter level, it will effectively bring the noise down

I just built a vero Iketera dual eq created by Drolo, very quiet, Fender tone stack based with two eqs in one 125B-sized box (if you rotate the layout and like 8 pots in that space.). It's on the forum at tagboard fx in the verified section under EQ.

There's a "hifi" mod to the Boss GE-7 that only requires a few parts and switching the op amps that's fairly straightforward. You should be able to find demos and instructions by googling if interested. Though I feel that the range of the slide pots change a bit, so you end up doing quite physically small adjustments for tweaks.

I'm more interested in something I can build a couple of.. still fleshing out a pedalboard / amp system that will do everything, including my laundry.

TH Custom has several EQs:

http://diy.thcustom.com/shop/3-band-parametriq-eq-slim-pcb/ (http://diy.thcustom.com/shop/3-band-parametriq-eq-slim-pcb/)
http://diy.thcustom.com/shop/3-band-parametriq-eq-full-control-pcb/ (http://diy.thcustom.com/shop/3-band-parametriq-eq-full-control-pcb/)
http://diy.thcustom.com/shop/5-band-eq-pcb/ (http://diy.thcustom.com/shop/5-band-eq-pcb/)

I built their 5-Band EQ and 1776's Six Shooter.
But I'd love to have a simple 3-Band EQ in vertical format with Master Volume (and some sort of voicing switch), like the EQD Tone Job, Barber BarbEQ, or Runoffgroove Tonemender. But there are no PCBs, to my knowledge. Does anyone know?

I built on veroboard the GGG's eq, layout by Sabrotone, the 5 pot version. But It was not so quite. The eq was good and versatile, but it add a bit of noisy, a bit annoying in the clean channel, much annoying in the distortion channel, so I quitted.

I was looking the TH Custom board. Is it that quite? I don't want to add noise to the sound clean or dirty, else I prefer not using an eq.

IS this the Iketera eq? http://tagboardeffects.blogspot.it/2014/05/4-band-gyrator-eq.html
Can I have more information about it? Is the 8 pot quite?

Thanks! :)

I was aware of the etch-PCB, but I meant none of the usual PCB-suppliers have a PCB for sale, Madbean quality and with pots soldered to the PCB.

Well, it would be awesome if the forum designed something like that, but trust me, it won't be me. Lack of basic knowledge....

It has two identical channels of T M B tone stack and a master volume for each channel.

What Bugera are you using? Just curious.
Title: Re: Looking for a quiet EQ project.
Post by: blearyeyes on February 20, 2018, 09:16:15 AM
Bugera V22 I've heard it's a clone of a Peavy.

Got all the materials and tools to start etching.  Might be a good starter project. Not too hairy, not too easy.
