Re: Joyo JF-16 British Sound (also Oxford/American/AC Tone/etc) Effects Loop?)

Oops, sorry, I meant fx loop needs to be after the level control. And also after the sansamp portion of the circuitry, kinda like a studio setting where in the effects are added after the mic. If the Dseed II isn't clipping then that's a good sign that they fixed the issue with the Dseed I. You can ...

Re: Joyo JF-16 British Sound (also Oxford/American/AC Tone/etc) Effects Loop?)

The fx loop should be before the level control somewhere. Thats how it is on the tech21 deluxe pedals atleast.

Does the Dseed II also give clipping issues?

Re: Joyo JF-16 British Sound (also Oxford/American/AC Tone/etc) Effects Loop?)

I had asked about the fx loop idea in the joyo actone thread. Apparently it puts the EQ controls after the loop, which is far from ideal with these pedals. Not sure how tech21 implemented it in the deluxe variants. Also the joyo versions dont have a lot of output when compared to the original tech21...

Re: Joyo schematics updates and component list. [schematic]

Gentlemen. Last week arrive in in my hands a Joyo California sound... For sure I reverse it... I note there are some componentes that are not present on the other versions that are mounted on this one, like the caps and the resistor on the filter after the CabSim before the Level pot. I also change...

Re: Joyo - JF-13 AC Tone [schematic]

Revisiting these pedals once again, here's something I noticed. In the original Tech21 pedals, the V1 units, R100 to R106 were laser cut. In the joyo clones, R100(R14), R103(R18) & R104(R19) are empty while the rest are present & used. I tried removing them to see the results & what I go...

Re: Behringer SF300 mods

It's been awhile since I had done the mods. If I remember correctly the Lows & Highs changed with the mods, the amount of gain changed or not I can't remember, it made it sound more modern. I can't remember more now because I don't use this pedal frequently. It was a single 1n5 cap(there's only ...

Re: Joyo - JF-13 AC Tone [schematic]

I was wondering about the addition of FX loop to the pedal, so that the pedals in the loop are placed after the preamp section rather than just placing them after the cab sim(as in after the entire pedal without a loop built in). Looks like the cab sim bypass mod would be the place to start for the ...

Re: Joyo - JF-13 AC Tone [schematic]

^ An easier way for the cab sim bypass mod that doesn't involve removing R28 or any smd component is to cut the trace between C18 & R28. After that connect wires from the points shown in the image I attached. Note: This doesn't work with the California Sound, I've explained it above in a few pos...

Re: Joyo - JF-13 AC Tone [schematic]

Yes, I did the exact same mod on all four of the models. The only significant difference is the California model, the you don't remove that R28 "0 resistor" from the board. On that model it's actually a 2.2k ohm resistor and it does something important. The value of the cap, I used 3.9nF,...

Re: Joyo - JF-13 AC Tone [schematic]

I've made this mod to all four of the Joyos. The Actone, American and British are all very similar, but the California model has some different circuitry. This is all four in bypass mode: https://i.imgur.com/DTKjbOq.png So in bypass mode, three of them are essentially the same pedal, and even when ...

Re: Visual Sound - Garagetone Chainsaw

I only just discovered myself that they'd hidden things under the potentiometers, the devious bastards. I see a 'Q103' under the rightmost pot (Volume), so I'm going to carefully desolder all the pots on mine so that we see what's in there. All the traces seem to be on the top-side of the board, I'...

Re: Joyo - JF-13 AC Tone [schematic]

The value of R24 in the American Sound I have in hand is 39k instead of 33k as reported earlier, anyone else have one in hand that would like to crosscheck this? It sounds like the ones in the demo vids I found online. I tried 33k in there, I sounded less fendery sort of but could be dialed in to so...

I can try to verify if the ckt is based on a particular schematic but I'm no good at drawing a new one. :oops: These are a little difficult to trace because the back side of the board is like not bare at certain common points, the component side is easier to trace except for the parts located undern...

Yeah unless I happen to have one of the two in hand :wink:

The DC jack is changed to a panel mount-bolt on type but the pcb is the same, along with the in/out jacks & footswitch.

Re: Visual Sound Garagetone Chainsaw

There are some components that looked like transistors but could be diode pairs in smd form, located under the pots. They aren't visible in the pics but can be seen from the side. The reason I say smd diode pairs is because their Drivetrain pcb has no visible diodes on it but a three legged componen...
