Jeds Peds Double SHO Crackle Boost is a take on the ZVex Super Hard-On pedal. The Super Hard-On is a boost pedal that's been taken from a popular (as we understand the case) Neve mixing console fader control. The in the mixing console the control would be the sliding fader. On a pedal, it uses 1 knob. The control simply controls the amount of signal going through a single BS170 transistor.

The thing that's so disappointing about the ZVex Super Hard-On pedal is that it's doesn't work well, or whatever, it's that ZVex charges something crazy like $275.00 for a pedal made of literally, 8 electronic components. Having sourced the electronic parts for our Double SHO Crackle Boost pedals, it's less than $5 for all the electronic parts. Then there's $5.00 for the enclosure, and $5.00 for the necessary hardware (jacks, knobs to affix to the potentiometer, button footswitches, etc...) and you have a functional pedal. $5.00, let's be generous and pay $10.00 for 10 minutes of work to the person soldering up the pcb, and $10.00 for the person assembling the pedal. Triple your costs for your profit margin, and the pedal should cost no more than $105. What's ZVex charging the extra $170 for?

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 even just working on a Super- or Double SHO pedal from the raw PCBs from the Jeds Peds.

Thermionic Studios has 2 Double SHO Crackle Boost pedals.

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 SHO Crackle Boost. That 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 also included additional "in" and "out" jacks and built 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.

So you may be doing a double- or triple-take at the

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

Artists

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