JHS Prestige

Postby POTL » 03 Aug 2017, 06:42

Hi
Let's try to trace this
This pedal came on a mini mini bomb, which was based on a single JFET transistor
The mini bomb schemaешс is presented below
Sch.png

Inside the pedal there are 3 transistors, one in conjunction with a diode (similar to SHO)
As well 2 transistors in a pair (something similar to mu-amp)
In the Ruby Red & Kilt pedals, a new booster is also being used (which is similar to the components with the Prestige stuffing).
JHS describes this as a 2-stage booster.

Maybe someone has a Prestige and he will share photos of guts in HD
Link to JHS Kilt, there is HD photo and booster inside

Nah. Prestige is a clone of Tim Escobedo's Duende jfet boost (not a mosfet version).

More Tim's stuff here: http://www.diale.org/escobedo.html

Perhaps you are confusing this with the previous version of the booster, which was called Mini Bomb
In the upper left corner are in the element one this is exactly a transistor, and the second is similar to a diode (although this can also be a transistor).
In the middle of the pedal, the diode resistor and the transistor are responsible for turning on the LED.

But thanks for the link, maybe I'll find something interesting.

What's this? I don't think it would pass any signal.

It won't. You'll end up with a FET that's not working at all and you'll have something like 7,5V DC at the output.

It needs to be like this:

On the other hand, i'd draw this circuit like this:

...but that's just me.
