a general layout for 'blend' ?

I have never used a passive blender that sounded any good.
you can try this one, Joel Purkiss' Buff n' Blend Ive had some success with it in the past.

OR this if you favor op amps, if you tie Send 2 to Return 2 and omit the jacks youll have a blender that blends with the dry. The Runoffgroove Splitterblend.

OR the Mooseapotamus Paralooper, originally designed for bass. If you omit the low pass filter on the clean signal you'll have a full range blend.

Good luck blending!

How would you alter the Paralooper to be used with guitar?moltenmetalburn wrote:I have never used a passive blender that sounded any good.

if you needed more specific information replace R6 with a jumper and remove C5, and it's now a regular blend pedal.

So, how hard is it to put a clean blend knob into a pedal? How does one go about doing this?
- earthtonesaudio
- Transistor Tuner
The answer to the first question depends upon which of the many ways you could answer the second question.
Easy and will work with any pedal:
Splitter at the input
Mixer at the output
-Dual-ganged pot turns effect output down while turning "clean" output up.
-Alternatively, separate volume controls for "effect" and "clean"
I'd use an op-amp for the mixer stage, for sure. This gives you the option of configuring it as a "summing amplifier" or a "difference amplifier" depending on whether the effect inverts the phase.
For the input, my first choice would be the other half of a dual op-amp, or a JFET if using a single op-amp.
...But there are many ways to do this, depending on your preferences.

Hi
I'm looking to build the following "B Blender" as designed by Sean M for use on a Bass. Not yet verified but if someone wants to cast an eye over the layout i'd be grateful before I commit to building it. The ground is on strip K and I do plan to connect the ground of all the jack sockets and battery to ground also.
This is from Sean's original schematic at his website

Thanks
Mark

I can now verify this works. I've amended the layout slightly and moved R5 to the other side of C8 as below.

Why don't you use some quad opamp, such as a TL074 ? It would be easier and take less space.
BTW, these 741 will be quite noisy ... and they may need some offset compensation.

I only give negative feedback.

Thanks for the tip Jim, maybe next time. Would a TL074 be less noisy than a couple of 741? Or is there a better design I could use for blend?

Sure it will!! But you can improve your existing design with other single opamps (e.g. TL071..) with better noise characteristics...moaner70 wrote:Would a TL074 be less noisy than a couple of 741?
- Are you a mod or a rocker?
- Uh, no, I'm a mocker.

Lolbou, could I substitute the 741 for a TL071 in the design without any other changes? Just a case of slotting in the new IC's?

Would this work for a Dry Blend control? Or would it overload the input, output or do something else strange? If so, how could this be fixed to allow for a dry blend on the output? Thanks in advance.
Sorry for posting this on every DIY stompbox forum but I want to get as much input as possible.

If I wanted to drop this circuit into an existing overdrive pedal, such as my MXR Distortion III, where abouts in the circuit would i want to put it? I have a pretty basic understanding on circuitry at the moment but im hoping to try to learn alot more from here... cheers.
