JHS 3 Series Live Stream with Josh Scott and Sweetwater
He shows the schematic for all of them and welcomes anyone who wants to copy the designs.
None of them take batteries. All of them are true bypass.
Josh comments at 1:13:00 that he thinks they are all great for bass. I’m guessing that’s because he’s selling them. The bass player in the video says the chorus is great for bass but doesn’t comment on the others. As usual it’s all very subjective.
Everything below this line is not my commentary. It all comes from what is said in the video. I’m just trying to sum it up since the video is almost an hour and a half.
Analog. It’s based on the HAO Rumble ODS that is no longer being made. Symmetrical soft clipping with a weird tone control called Body that changes both EQ and gain of how it clips. The clipping switch goes between silicon or LEDs. He shows the schematic and welcomes anyone to copy it.
Analog. Slightly modded RAT with clipping switch that goes between stock silicon or LEDs (Turbo Rat). OP07 op-amp.
Analog. Two transistor mid 60’s topology. Modded version of a Silicon Fuzz Face with bias control and fat switch to add more low end (He says this makes it great for bass). They called it a Fuzz Face for 2020 and said it was very different from the JHS Muffuletta.
Analog. Ross/Dyna Comp circuit. Josh says there’s no groundbreaking engineering here. It was built based on classic mods to the Ross version of the Dyna Comp. He also says that all of their previous compressors were based on the Orange Squeeze topology which is a much more subtle compression effect. He also makes the statement that noisy compressors are usually because of a cheap power supply somewhere in the chain of pedals.
Reverb, Delay, Chorus
All are digital and based on the FV-1 chipset. They all use the same PCB with different code loaded into the chip allowing for a big cost savings. He commented that this chipset is used by tons of companies; Keeley, EarthQuaker, Line 6, etc. All three are inspired by vintage pedals and built with 2020 sensibilities.
At 1:17:12 Josh talks about expanding the line considerably including creating bass specific models. But don’t expect anything with midi or tap tempo since you can’t do those things at this price.
At 1:21:40 He talks about what they’ve done to be able to make these pedals affordable and still maintain quality.
