Madbean Turnabout (JHS Andy Timmons)
Brian’s take on JHS Andy Timmons pedal. This is not an exact clone of the original circuit and the video is for reference only:
JHS
JHS Honeycomb Deluxe
Here’s JHS’ Honeycomb Deluxe tremolo. Or something close to it anyway. It’s a modified EA Tremolo with an extra switch to control speed and a extra footswitch to switch between speed controls. Ian McDermott came up with a work-a-like for it, so this layout follows his schematic. This layout features board mounted pots and because … Read more
JHS Little Black Buffer
Here’s a simple buffer from JHS. It really only uses one side of the opamp (why not just use a TL071?) and the extra resistors on the other side are just to meet the manufacture’s specs for an unused side. I couldn’t find a schematic for this one, but drew one up from lvlark’s vero … Read more
JHS MiniBomb
Here’s a simple clean boost circuit built by JHS. It’s really just the Tim Escobedo Duente JFET boost with a fixed resistor instead of a trimmer. Because of that you probably want to socket that resistor (5.1k) and adjust to the J201 you use. Or you can just squeeze a 25k trimmer on there like … Read more
JHS Superbolt
Here’s a popular JHS pedal that emulates old Supro/Valco amps: the Superbolt. It has a remarkable similarity to the Run Off Groove Supreaux and Supreaux Deux. It seems to be a slightly modded Supreaux, with the high/low switch and 18 volt supply of the Supreaux Deux. A charge pump is also added so the pedal … Read more
JHS Morning Glory
The JHS Morning Glory is a modified Blues Breaker overdrive, but with an added JFET output buffer to increase the volume. The original Marshall circuits barely made it above unity with the volume maxed (see the video below), so the output buffer is a good improvement over the original. There’s also a high cut switch … Read more
JHS Little Black Buffer
Traced from gutshots on the blog forum posted by hahafender, thanks for the pics buddy :o). Some of the traces on the unused side of the opamp weren’t visible but the left hand side is a generic opamp buffer and that’s the important bit. I think the resistors used on the other side we’re just … Read more
JHS Morning Glory
Modded Blues Breaker.. Personally i have pretty high hopes for the circuit… There’s a lot of hype out there these days with overdrive pedals and the last thing we want to do is to add to the noise. As you may already know, almost every boutique overdrive on the market is a modified Tubescreamer of … Read more
Escobedo Duende JFET = JHS MiniBomb
The circuit for these two are verbatim. Escobedo just has a trimmer to bias the JFET, where JHS has 5K1 resistor. He probably uses matched j201s… JHS info: A good booster is often the most underrated tool a guitarist can own. When placed before your overdrives or distortions, a thicker, stronger and more saturated tone … Read more
