A DIY Custom Band EQ Pedal - DBE Rock Bottom

[somedude]

EQ charts are just what I need. Perfect. Thank you.

Great looking project Paul & Eric! Having the ability to fine tune the EQ frequencies, will appeal to a lot of builders. Keep up the great work!!

2 years and no one noticed the Valvestate preamp seems to have been based on the Mesa....I've had a few and love my AVT150...going to put an EQ in the loop and go nuts tonight...thanks for all you work.. curiosity..and passion for the tone and parts that make the tones. Love your channel. Cheers from Wisconsin, US.

That is so awesome, brilliant. The can doesn’t look too bad squished up. Has some character. You did parallel park!

[RobMods]

Thanks for a great project. This would make a nice little bass preamp. Perhaps a bigger input cap, and maybe use the spare opamp as gain or a DI trans buffer. So many players are going direct at gigs these days. For choosing EQ points, I usually shortcut the process by using a DAW to find the freqs and Qs I need. Saves a bit of breadboard time. Loving your channel!

[Fireman]

Thank you for this! I've spent days looking for a way to build a specific EQ and youtube finally brought me here. Excellent content, and thank you for the store too!

Can you do a video on a "q" toggle on each frequency for up to three frequencies to select

[cdburgess]

Sincerely, completely adjustable. I’m going to have to listen more carefully to my time and try this one. Very cool

[notehappy]

Great stuff - a thumbs up from me!
About the volume control; did I miss something or does the volume (as on the video) have to be on full on to match the bypassed level? If so, you can’t make any level boost? Because the pedal seems to work very well, with a build (or two) you could distill a different flavour from the amp with one, and have another pedal with its own charasteristics AND level for solos.

I wish I could post a pic here becuase I have a question. I have a boom box here from the 1980s, one with two tape decks and a million settings and options. It's got mono jack inputs I can repurpose and I'm fairly sure I can use a lot of the electronic components, resistors, capacitors, transistors. When I bored I I take stuff like that out of things and thow it in a box in case I want to make a trebel bleed circuit or need something. Anyway, on the front of this beast is the prettiest square little 5 band eq with sliders you ever saw. Lol and I can just hear it begging me to use it for something. I was wondering if I could use it to make and EQ pedal. I mean, i could probably run a guitar through it as it is and use it. But I was wondering how possible it woudl be just to take out the parts I wanted and put them together in a box? I know you cant really answer this question without seeing it, but I'm going go ask it anyway. Which was why and how I found your video. I guess I wanted to find out before I tore it down and took the parts I know I would need. It has several pots in it also. I'm going to look at your guide, and I know I'll need a casing. Thats no problem. The only thing I dont have and may need is a PCB board. But the board may already be set up for this eq and all I will need is a foot switch. Take out the Jack's and the eq, wore them up in a box with a power jack. Wire in the footswitch and go to town, so to speak. Im not new to electronics but I'm no expert either and I've never biult an effects pedal of any kind. And if I'm going to try, I at least want to biuld something I need. It's about the right size and everything.Anyway, I've asked my question I know you csnt answer without seeing. Lol, I'm probably going to cannibalize it either way.

G'day. I'm planning to modify this design to be a 3 band (maybe shelving top and bottom - not sure yet..). I think I can work out the filtering stuff. But, is there a good 3 band version already?
Thanks, and thank you for all the great info you're sharing here on the channel. Ty (Lismore NSW)

[tomfoolery]

Choosing the freqs each person wants to use . Tht b great . How wd ya find out what would b best for ya ?

[tybowesformerlygoat-x]

Glad to have found you.
Where are you in Australia? (I'm near Byron.)

[ryanbird]

what is the formula for working out what capacitor/resistors i need for a chosen frequency? Specifically I'd like 40Hz, 160Hz, 650Hz, 2.5KHz and 40KHz (maag eq air band style)

[radhockenheim]

Hello, I have a spare boss style enclosure with a terrible overdrive (90s Ukrainian Boss copy) and I will use that enclosure for the EQ pedal. Greetings from Ukraine❤

[astorina]

Hello, can i buy the full kit from you (components, box etc) or just the pcb as this seems to be the case on your web site ? I cannot find more than the pcb
Great idea and very interesting videos
Brgds

[mrdeer]

Different question. Why is there no much parametric eq pedal out there?

[sonicpickups]

Try spaying a couple coats of clear acrylic lacquer on those thermal labels before epoxying. Dust the first layer, let dry for twenty minutes and do a second heavier coat, maybe two. Let it dry for eight hours. Should keep the print intact.

[ejnordberg]

Do you have any plans to restock the pcb?

[agentefarah]

There's some time I'm looking for information on the eletronic parts of a loop station/looper pedal, and I don't find it anywhere, there's any reason for it?
