I don’t think the originally posted circuit would work. The 470R needs to be bigger to isolate the two signals so that muting the clean doesn’t nearly mute the dirty. Bringing that up to 10k might work well enough without changing anything else. Another way to do additive blend is to exactly...

the volume pot is linear. Replacing with log would help dialing in reasonable volumes.

Nice info ^. I’m planning a build, I’d like to have the cap changes on a switch so that the full low end original circuit is still available. Obviously only 1 capacitor (cathode bypass) is easier to switch out than 4 (coupling). Would you say the 1uF Cathode bypass is a similar effect as the...

Have you looked at the Dung Beetle (Basic Audio Scarab Deluxe)?

Not seeing anything in the pics. My process would be: Check the DC voltage at pin 8 (should be 9v). Use an audio probe to check for signal at various points in the signal flow.

Maybe try running the ROG Tone Mender circuit in spice and see if that gets you in the ballpark, then you could tweak capacitor values or try to match the exact amp values in the tone stack

Kudos for modeling it in spice. It’s a tweaked Timmy circuit, so I wouldn’t have expected to see a mid scoop. I take all specific-amp-in-a-box pedal claims skeptically… doesn’t it depend a lot on what amp you’re running into? Unless it’s like an iridium - full amp/cab sim that’s meant to go...

Check out the Run off groove tone mender circuit. I’ve done a slight variation where I follow the tone stack from a Super Reverb. Not sure it’s what you’re looking for but it will at least impart some of the EQ If you play with the online Tone Stack Calculator, you can see that 3 band EQ...

No hardwiring, just leave the diodes out for program 0. The bit values on pin 15,16,17 decide which program plays. 000 = program 0 001 = program 1 010 = 2 011 = 3 100 = 4 101 = 5 110 = 6 111 = program 7 0v means bit = 0 3.3V means bit = 1 The 100k Rs pull all 3 pins down by default. The...

You could also get the Pythagorus and just not populate the toggle sw. Same result (only patch 0) as the above comment.

Doesn’t make much sense to me, but I’m curious what you find out with other diodes, etc

Pythagorus and arachnid are the same, except arachnid allows up to 8 patches on a rotary switch. You can’t partially select patches, you’re on one patch at a time. The VHS uses 4 separate patches for no reverb/or chorus, reverb only, chorus only, reverb plus chorus. Basically, the code is...

The VHS uses one Fv-1 chip for reverb and chorus. You couldn’t really do all three in one fv-1, mainly because the fv-1 only allows 3 knob inputs. The smallest/cheapest would probably be the VHS pcb and a separate delay pcb (take your pic, pt2399 or fb-1 based). The VHS toggles for selecting...

That wire working with these boards looks fine to me!! I don’t remember the details super well. I read through my post and I said I used JB weld to stick them both in one of the Housing halves. Sounds familiar, I’m sure other glues would work too

Do they look similar to my pictures? I just used 22awg solid, same as I use for everything.

Waaaayy late, but recently I was looking at this so I’ll put it here in case you’re still wondering. The Caesar does for sure cut low end from the wet (vibrato) signal. I had been under the impression that the Julia was a work-alike to the Boss CE-2. But the resistors in the mix section seem...

I made a Runoffgroove supereux deux a while back and liked it a lot.

If you just want to toggle which eeprom is making the sounds, yeah it should work on the same principle. If you also want to toggle which socket gets flashed, you can use a DPDT switch to connect/disconnect the PCB pins 5&6 to the sockets. I don’t have a perfboard layout. You don’t need any...

No LED for the light sensor? (LDR) How it’s supposed to work: LED blinks, when the LED is dark or dim, the sound gets quieter.

You’re using two 9v batteries in series (18V) with a 9V regulator? Why? (If I understand what you’re saying, though it’s kind of a guess).
