effects blender layout

[Beedoola]

I'm looking for a single loop blend circuit. Anyone have a layout? I've seen some online but I've not seen comments about them - as to how well they work.

blend?? like mixing signals??

Search for the Paramix, it blends wet (in aloop) with your dry signal and, design wise, is the Rolls Royce of them all.

The JMK PCB Panner might be what you're looking for. And JMK PCBs has a sale going on...

Just as an aside:

IMO something that is important to have with a blend pedal is a phase switch (I believe the Paramix has one).

Some pedals invert the phase of the signal.

Mixing an inverted phase signal with an in phase signal can have strange, and some times 'tone sucking' effects.

A phase switch makes it really easy to make sure you are mixing the blended and dry signals correctly.

Exactly.
In order of my preference:
Paramix (no phase issues)
B-Blender opamp based, sonice and colorless
Buff-an-blend, simple but not "transparent"- though that's another man's "warm"
Paramix is theonly one with phase inversion, may not be an issue, just checkout the circuit you intend to use it with.

If you are into perfboard, there is also a layout for the ROG splitter-blend which also has phase inversion:

Just link the red send and red return pads (or even better use switching jacks) and you have your dry signal to mix with fx loop.

I would agree with you guys to a point, however each of these options here have another inherent issue themselves - they don't actually properly mix the signal with the clean signal. They aren't actually balanced mixers, which is what the Panner/Paralyzer solves by sending the unused signal to ground. You actually go from full wet to full dry with a 50/50 mix in the middle, which none of those other options give you. And the PCB is small.

The fraction of circuits that would require a switch to flip the phase inversion is not very large. If in fact someone did have a situation in which that was an issue, there are other options.

sweet, ordered.
