Double SHO Crackle Boost
Jeds Peds Double SHO Crackle Boost is a take on the Super Hard-On pedal (ergo the "SHO" in the name). The original Super Hard-On is a boost pedal that's been taken from a popular (as we understand the case) Neve mixing console fader control. In a mixing console the "boost" (or more accurately, the volume) control would originally have been a sliding fader. On the pedal, the boost is controlled with 1 knob. The control knob simply adjusts the amount of signal going through to be amplified by a single BS170 transistor.
The thing that's so disappointing about the original SHO pedal isn't that it doesn't work well (it does), it's that the original maker charges something crazy like $275.00 for a pedal made of literally, 8 electronic components and didn't even come up with the original circuit.
Anyway, the Double SHO Crackle Boost pedal is TWO Super Hard-Ons in one pedal. Plus we offer a few more features on our Double SHO Crackle Boost pedals that you won't find on the Super Hard-On, or, likely on any other Jeds Peds Double SHO Boost.
- Thermionic Studios has four(4) SHO Crackle-Boost PCBs. When we're done coverting them, we'll have two(2) Double SHO Crackle-Boost pedals available for rental.
Controls
- Knob 1 - "Crackle Boost 1":
- Knob 2 - "Crackle Boost 2":
- Switch 1 - "Series / Parallel":
- Knob 3 - "Volume":
- Footswitch 1 - "Boost 1 On/Off":
- Footswitch 2 - "Boost 2 On/Off":
There's a "standard" way that Jeds Peds recommends setting up the Double SHO Crackle Boost. That recommendation simply consists of feeding one boost into the other. We decided we'd like for our pedals to have a good bit more versatility. So we'll also be including additional "in" and "out" jacks and building in some additional enhanced functionality so the pedals can be more flexible.
Jacks
- Jack 1 - "Boost 1 In Serial & Parallel":
- Jack 2 - "Boost 2 In Parallel Only":
- Jack 3 - "Boost 1 Out Parallel Only":
- Jack 4 - "Boost 2 Out Parallel Only and Boost 1 Out Serial Only":
Parallel
When the switch is toggled to "Parallel", the two boosts are independent of each other:
- Plug two different signals into Boost 1 and Boost 2, and they will be boosted independent of each other
- Volume knob is bypassed / turned off.
Serial
When the switch is toggled to "Serial", a few things happen:
- Signal from Boost 1 is cascaded into Boost 2
- Jack #2 (in) is bypassed
- Jack #3 (out) remains active
- Volume knob is enabled to assist in taming a signal put through 2 boosters.
Here's a quick explanation chart:
| Function | Routing | In | Out | Function | Volume Knob | Footswitch 1 | Footswitch 2 |
|---|---|---|---|---|---|---|---|
| Boost channel 1 | Serial | Jack 1 | Jack 4 | Boost 1 cascaded into Boost 2 | Active | Active | Active |
| Boost channel 1 | Parallel | Jack 1 | Jack 3 | Boost 1 only | Bypassed | Active | Active |
| Boost channel 2 | Serial | Jack 2 | Jack 3 | Jack "In" inactive | Active | Active | Active |
| Boost channel 2 | Parallel | Jack 2 | Jack 4 | Boost 2 only | Bypassed | Active | Active |
Bypass: True
The JedsPeds Double SHO Crackle Boost is true bypass.
General Information
The layout of the JedsPeds site was different at the time we purchased our PCBs. Jed now offers more than just raw PCBs, and sells PCBs + parts, and even full kits now.
Pedal Manual
Phase Inversion: It Depends
There are a few other pedals we have that also say "It Depends". We agree that on first glance this seems like a wishy-washy answer, however, we also provide the means by which to understand, based on how the pedal is set up, how to determine if the pedal is inverting phase or not.
The Super Hard-On, by itself, inverts phase. The Double SHO Crackle Boost is essentially two Super Hard-Ons stacked inside of a single pedal. Boosts typically run off a single active transistor, that amplifies signal, but that also inverts phase. So when the pedal is being used and only one boost in the pedal is being used, then the phase will invert. When the boosts are cascaded one into the other, the phase will invert on the first boost, and then revert on the second boost.
So here's how it'll work:
Series
When the boost toggle is set to series, Phase Inversion : No
Parallel
When the boost toggle is set to parallel, Phase Inversion: Yes

We are currently unaware of any artists actively using the pedal now, or who have in the past.
