IN PROGRESS Great Eastern Variable Crossover

[Haz]

Wouldn't this be a nice utility pedal?

 

[Fretless]

Utility, yes. Creative uses, yes. It’s a very interesting approach to FX.

i've been begging for something like this for years. was going to start throwing ideas at a wall on a breadboard to try to figure it out, but if someone wants to just trace this one instead

I would love to build this XO thingermabobbie.

I'd maybe call it the "LC" with a set of Submariner Dolphins for the graphic:















A DIYer could do something like this with PedalPCB's Channel- Splitter (or Mixer), add HPF, BPF, and LPF.
It'd actually be better because you'd have the BPF (or a DRY) signal.







I've got the THCUSTOM Pro-Cessor V3:

 Signal Splitter,​

 Signal Mixer,​

 24dB Highpass filter​

 24 dB Lowpass filter​

 Two parallel effect loops​

There's a Pro-cessor V4.2, but the only difference is that you can't choose the type of enclosure for V4 because the jacks mount on the PCB — I didn't like the order they were configured in.


Here's THCustom's prototype, note with the Pro-cessor you have the ability to choose direct, HPF or LPF for BOTH channels:

Omnilooper is cool.

"It consists of three effect loops (Inserts), two of which are equipped with filters (1x LPF/1x HPF) with -12dB/Oct. per Filter. The filters position in the chain can be switched (Filter -> Insert, Insert -> Filter, or Filter off). If turned off completely, three parallel fullrange effect loops are possible. To be able to use even effects which are normally only utilizable directly in front of".

And it has a Bass-EQ (bass boost only, 60Hz, Bell-EQ), who-hoo, more here.

@Fuzzonaut
Is Julian offering the Omnilooper again/still?
His website message still says he's done-done as of 1/ 9/ 2022.

The Omnilooper is the one thing left of Schalltechnik_04 I still want/need.


EDIT: I see it's at MusikDing.

@Robert just sent mine back to me. Pretty sure he traced it.

This thing was available for a while. Not sure if they discontinued it or what.

 

[Aentons]

Personally, I'd prefer modular single channel strips you can chain together into a standalone mixer board.

 

[Morbidpale]

Have you seen this build? It lacks the features but works great.

Also this one. This one has a phase switch

that thing is way overkill. super rad design. 65 dollars for a PCB with a lot of features i'd never use. it would be a lot more useful for me to have something simpler like this great eastern

 

[benny_profane]

Do British companies legally have to use ITC Johnston (or derived) like Canadian companies have to slap a maple leaf on the trade logo?

 

[maertz13]

breadboarded this, which is intended for line level signals, but it worked, technically. i'm getting about a 20dB loss. can't imagine it's as simple as boosting it back to unity and then adding an effects loop

 

[jesuscrisp]

That thing has abysmal input impedance. You could try putting a buffer up front. Also increase R5 and R6 to 10K.

Have you checked out Fuzz Dog's Fat-Ass Blooper?

Blends clean signal with whatever's in its loop and has a toggle-able low-pass filter on the dry.
It's just missing a phase switch, unfortunately.

Available as a kit or just the PCB...

yeah, i've got a couple. not enough control. need a variable crossover. the plan is to end up with something similar to the darkglass X series.

 

[bhcarpenter]

I’d likely build several of these if they were available as a PPCB project

 

[notTHEwillienelson]

Dropping in to say I hope this one is still in the works. I'm definitely planning to buy several boards when it drops!
