Custom Blender Idea - Help me think this through

If it were me, I'd personally leave the LPF to a dedicated cabinet sim, which would offer much more flexibility. I like it when a stompbox has one purpose, and does it well.
For symmetry reasons, I'd keep the FX loop on the clean channel (I'd probably stick an EQ and/or a compressor there).
How many footswitches would you put on that ?

 

I like this idea.

Complex, but thorough. If it was going to sound like poopie, Josh wouldn't build it.

 

This is what you need, for €9 (PCB only, but only hardware, passives and 4× TL072 needed)
Pro-cessor V4.2 PCB – TH custom effects
Splitter/blender with selectable HPF/LPF for each branch.
More info in Build instructions.
I´ve found it only today, looking for the same thing as you ;-)

 

Phase switch? To avoid loss of bass from phase cancellation when blending the processed and straight signals.

 

If it was me, i'd want to have a %/level control over the HPF on the dirt pedal loop - could be a good way to tweak mids as different ODs/distortions will have varying mids content.

Otherwise - sounds great!

 

If it's not terribly complicated (and I don't think it is), you could add a switch or a footswitch that puts the two channels in series instead of in parallel, and then you could use the clean channel to boost the input of the dirty channel and get a lead boost or something.

 

I just grabbed this off of a guy on Basschat, seems to be what you're looking for -- the LPF is on the clean signal. It destroys the Wounded Paw V1 I had. I'm sure Tom at Cog could make one for you if you ask.

Edit: Well, maybe not everything you're looking for, but a lot of it

 

That's a good question about L/HPF vs crossover. The FEA Photon Fuzz uses dipswitches to configure pre-set frequencies to low pass the clean channel, and high pass the dirt channel. I haven't noticed any weird effects from overlapping mid frequencies, but I'll try to mess around with these switches with this in mind when I get a chance - interestingly, you could configure it to have no signal between 110 and 220hz

For #2, if you already have a low pass on the clean channel, I'd think you would want the post-dirt low pass to be for the dirt loop only

 

Yup makes sense...curious what he comes up with

 

Very interesting... I'll be following this.

 

I'd be also good to have two dedicated outputs (one for each signal path) just in case if you prefer to biamp in the future.

 

Not really a "blender" but I'm getting down with a clean DI/dirty DI. Plan on using my Noble pre-amp/DI straight away as the clean tone and Dirt Slayer from Josh as my dirty DI. I plan to mic as much as possible but the Dirt Slayer will do a couple of things to improve tone if I can't do so:
1) XLR out will have both HPF/LPF, and
2) Parallel Thru will only be HPF (let's cabs naturally roll off high-end).
I should be getting it in a month or two. Kinda excited.

 

Look at Saturnworks pedals. Pretty inexpensive and a few different options based on what your looking to do. This is the one I have specifically. I have 2 outputs out of my Boss TU2 tuner which is first in line. One out goes direct to this pedal which is at the end of line before my amp. The other out goes thru my pedal chain and then into the other input of this pedal. Can control either input with individual footswitch, and has volume control to adjust either input as well. I set my clean level 25% higher than my dirt level as the dirt tends to have higher gain anyway.

Only downer here is when I activate my tuner, the bypass output is still active and not muted, happens to be my dirt. No biggie I just turn the dirt signal off at the Saturnworks so its just a matter of stomping 2 times/places instead of one and its only when I need to tune.
