The JHS Haunting Mids is an EQ circuit that controls the mid frequencies along with giving a 10dB clean boost. From the JHS site: The Mids and Sweep controls work very closely together so you can find the perfect frequencies to boost or scoop mid frequencies. When the Mids knob is at 12 o’clock, no frequencies … Read more
Here’s the newer version of the Angry Charlie with the 3-band EQ. Pretty much the Crunch Box with a 3-band Baxandall tone stack (similar to this) tacked onto the end. Pots are board mounted and it should squeeze nicely into a 1590B.
From the source: The JHS Twin Twelve is the first effects pedal to go after the sound of the short-lived but revered Silvertone 1484 Twin Twelve. Available through the Sears catalog from 1963 – 1967, the Twin Twelve was not regarded in its day as a premier amplifier. However, modern players looking for a vintage … Read more
Unrelated to the Angry Charlie circuit, the Charlie Brown emulates the brown sound of a JTM45 amp and is a variation on the zVex Box of Rock without the boost section. The input stage is an AMZ Mosfet Booster (replacing the SHO input stage of the Box of Rock to avoid crackle in the gain … Read more
I’ve gotten a few requests to redo the MI Audio Crunch Box with board mounted pots. How is that relevant to the Angry Charlie you ask? Well, it’s the same circuit. JHS added a cap in parallel with the existing cap coming off the Presence control to ground which tames some of the highs. So … Read more
Here’s the original Twin Twelve from JHS. It’s an emulator of the old Silvertone 1484 amp. Like a lot of amp emulators (including their Superbolt) it uses JFETs and an 18v charge pump. The schematic can be found here, and I added the charge pump from JHS’s Superbolt. Set the trimmers to around 9v and … Read more
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:
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
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
