My Super Blender Pedal Idea... Help

tomhanzo · #1 01-07-2010, 03:51 PM

I have looked around and came up with an idea for a blend pedal. Here it is

Did i do it right?

your not gonna get unity gain on your clean side with that tone stack(assuming thats a buffer) and personally i'd wire the switch differently.

So i couldnt even get close to loud enough? What if i cut the body knob out?

How else could i do the switch. I just have one of those switches laying around and thought i would use it cause i have no other.

What are you trying to achieve with the tone and body controls and more importantly why?

For the switch you want to wire the send and return on the top row, the in and out on the middle row and then wire the bottom rows to each other.

Well my goal is to send my original tone to the loop and have tone control over the clean that is added into the blend. Does that make sense?

I got the idea from the new Fender Sub-lime Fuzz. It has the cross whatever in it. I guess this is just something i thought up from that.

I think If you could have a simple tone knob to change the character of the clean mix in the blend would be cool. It will force the clean mix to fill in a particular sonic space rather than my entire clean sound.

Oh and on the switch I wanted everything in the pedal to be bypassed. The way you mentioned would keep my tone section active wouldnt it?

So basically you want two loops within the pedal and a bypass on top of that. To start with you're going to have to buffer the the original signal then send one part to the effects loop(send/return) and the other to the tone control, each of these will then have to be buffered before going to the blend knob. So it's pretty similar to the paralooper except you want a tone control instead of just the low pass filter on the paralooper.

Here's the paralooper circuit, the bottom signal path is where you'd add your tone control.

Also worth taking a look at this thread and see how the paralooper with adjustable high and low pass filters works. Personally I find that more than enough as I don't want to change my clean tone from what it is.

paralooper with LP & HP

the switch would still be wired as said or can also be wired for a status led if you use a 3pdt switch.

Dude you are a serious hero. Now does it matter where i put the tone section? I know you said bottom signal, but should it go just before the blend knob or what?

moose23 · #8 01-08-2010, 10:27 AM

It should go before the opamp(triangle) and after the low pass filter (C5). That is if you want the to cut some high end from your clean and some low from your dirt. If you don't want any cutting you leave out C4 R5 C5 and R6 which are the two filters, I would stringly advise leaving them in though.

tomhanzo · #9 01-08-2010, 01:41 PM

I may cut them out and just see how it sounds with out them. I want to try and get as close to the pure tone knob sound as possible. I may leave the high pass though. I dont know.

This will be the first real build i have ever done so its gonna take me a while to get this thing going

moose23 · #10 01-08-2010, 01:54 PM

Have you a breadboard or ideally even two? You could build the blender on one and the tone control on the other. That you way you can tweak the tone to your exact taste without worrying about the blender and vice versa for the blenders high and low pass filters or just the high pass if that's the way you end up going. The tone control you have varies between a high and low pass filter so your probably right in leaving the low pass filter out. Let us know how you get on with it.

Hawkbone · #11 01-09-2010, 12:29 AM

hey are these pedals DIY only or can you buy them? How hard would it be to modify it so the signal doesn't get recombined but sent to two different amps? I daresay I could pull off the build if I could find the time to do it.

drumandbass · #12 01-09-2010, 02:59 AM

I've got almost the same idea. except with out the tone control.

I would love something with 3 loops. Each with its own volume control when it comes back in. So i can control the mix going out to the PA/amp.

Any idea on how the PCB would look like?

tomhanzo · #13 01-09-2010, 04:27 AM

Hawkbone, I found all this around the web for free. No kits sorry. Umm do you mean have two out puts after the blend or two outputs both with a blend?

drumandbass, I have no idea lol. Im not good at this stuff yet. I'm sure it can be done cause i have seen them before, but i dont know where to begin.

Haha, thanks!
I have no idea where to start as well.

Actually I could pass on the idea to a local pedal builder. But I'm concerned about a few things.

Whats the best way to split the signal to different loops without any tone loss. Buffered? or another way?

And when it gets back into the box with the volume control, would it stack over each other or be independent and goes straight to the output. I have no idea how to phrase these in a way the guy would understand. Or at least so he wont make it and it not working to what i expect.

tomhanzo · #15 01-09-2010, 05:11 AM

well you can make them go to what ever out puts you want. Its up to you. They can all have their own volume controls as well

Buffered is the way to go, all sorts of problems can happen if you don't. Your local pedal builder should know or be able to figure out the details for you.

Moosapotamus in the thread I linked to makes the paralooper for sale, it's his design too btw.

I was thinking it would be cool to have the option to recombine the signals to send to one amp or just leave them separate and send to two amps

I've tried contacting him but no success so far.

For sending to two amps you can plug the end of the effects loop into a second amp instead of the return on the pedal. Basically taking the lead from the last pedal to the second amp.
