Selectable pad on the DI output: 0db, -15db, -25db (approximately).
I'd like to build a Flying Pan clone with stereo inputs. How much would that change the circuit? Would it be complicated?
What are you aiming at? Mixing both before being processed? Do you want each input to be processed seperatly? Do you want 2 outputs or four? What would your signal chain look like?
Two inputs, two outputs. Signals not mixed, separate with the tremelo switching from one side to the other. Phase selectable to affect either or both channels.
So you want to eliminate internal splitting of the signal and feed it instead with your two input signals if I understand correctly? Do you have a verified schematic? I'd check out where the signal is split, cut the trace on a breadboarded version and send my second input there for a start.
Here's something I worked out for an onboard preamp for a bass built I'm doing...
It's a "One knob pulltec trick" circuit. I needed a way to do it as a wet/dry 'contour' knob with a single, single-ganged pot. I personally like the dip around 300hz, but there are a lot of frequency choices that work for different purposes, especially if you adjust the intensity of the boost and/or cut. Hope this is useful for someone!
I discuss it more in this thread

Guess you'll need two of those if you want the full feature set. Did you have any ideas when looking at the schematic?
So are you trying to do this:
With instrument A and B, and amp 1 and 2, if the pedal normally oscillates between A1 <-> A2 , you now want to oscillate between A1+B2 <-> A2+B1?
Like I've said, to me it sounds like you need two circuits and then a separate panning circuit. Quite a task for a first (?) project... Maybe I've got something wrong tho. Have you tried doing a block diagram (panning block, phasing block, ...) to find out which circuitry you need in which order to achieve that? Don't think I can give further directions on that cause of time and size of your scope but I will follow with interest.
I deleted a comment, if you’re looking for it..
This is still a tricky one for a first project, but maybe not absolutely insane if you’re patient. I’ll see if I can sketch something up, but if you’re coming into this relatively blind it will be hard to come up with a layout if you can’t take a schematic and translate it into a board of some sort. Perhaps it would be possible to combine two of the actual purchasable boards , albeit a little wasteful
(DEFX) LOW BLOW (Katanasound Super Bass Fuzz)
This is a very cool fuzz, that somehow has it's own thing going on, combining "a bit of Superfuzz, with a bit of Green Ringer, providing extra spicy top end to a fuzzrocious fuzz", as Deadend says.I matched diodes (D4/D5) and transistors (Q4/Q5) and the octave on the footswitch is very strong.
As for transistors, I have 2x 2SK30A and 5x 2N2222A in there. GE diodes are D9E (D4/5) and D311 (D6/7).
And some "japan/sword" themed graphics, because Katana.
Been playing with the 3d printer again. I don’t have a 3d scanner so I took all measurements with calipers and a ruler. It took several attempts to get it right.
I have built several circuits but haven’t been able to get myself to work on the enclosures yet. Recently I have built the mxr el grande fuzz on an etched pcb, the Dunwich Fuzz Throne Deluxe on stripboard and a Prunes and Custard on etched pcb. Of the 3 , I have an original P&C and the etched version comes very close when compared. The original has a little more pronounced octave effect to it. I need to do some tweaking on it.
Disclaimer on the enclosure: I am in no way trying to step on GisserDs’ toes or anyone else for that matter. I’m just a guy that likes playing with toys in his garage in his spare time and making stuff. This is what I do instead of getting drunk now.

Good man. Scanning takes a lot of work to prepare the data. Maybe you can take advantage of step-Models from manufacturers or datasheets. Keep in mind that you have ultimate freedom: No need for angled sides, screws where you need them, recessed switches etc. Have fun!
