HAO Sole Pressure

It's been a while but I saw this little one was missing, and as I own the pedal and like it think it's a worthwhile addition.  So thought I'd try to get back into the game even if it's a bit diddy and embarrassing compared to what the other guys are posting :o)

Info about the original:

Like the Rust Driver, the HAO Sole Pressure was designed to recreate the classic sounds of one of the most desirable guitar amps in history – in this case, the legendary ’59 Tweed Bassman 4x10 combo. The HAO Sole Pressure contains carefully selected components that allow the user to dial in the smooth, creamy overdrive of this classic amp, right down to the characteristic low-end sag unique to the combo version. Dual knobs control Output and Drive levels while three switchable EQ curves offer plentiful tonal options without compromising your guitar sound. This dual control configuration also allows to the Sole Pressure to act as a semi-clean booster to coax more character out of your amp. If you’re looking for the classic Fender amp tone that defined a generation, the HAO Sole Pressure will let you achieve it with any guitar and amp in any playing situation, without the hassles of owning vintage gear.

Lovetone DoppelGanger (Gigahearts FX Doubel Ganger)

It's been a while since I've uploaded a monster layout. Therefore...
Here is LaceSensor's version of Lovetone DoppelGanger analog phaser.
You can find all info, build doc, bom and manual on Madbean Forum here (free login required)
You could also buy PCBs when available.
Here is a video of the original pedal (slightly different from this version)

Tone Factor Cream Pie

A small Germanium Booster/OD.

Original using NPN Germanium Transistors.

Since PNP Germaniums are more readily available, cheaper, and reliable here's a PNP version. Remember you can NOT daisy chain this with NPN devices.

And here's a layout that's a touch larger, but includes an onboard inverter to give you the ability to daisy chain it.

Suggested hfe for the transistors is between 90-120hfe. The trimmer is used to set the collector voltage. Suggested between 3-5V, with a lower voltage giving a dirtier boost. You can replace it with an offboard pot to allow for on the fly adjusting, like the layout below.

Top Gear Fuzz Sustain

A super rare pedal from the UK from 75-77. When they come up for sale they go for stupid amounts of money, >$700. The only information I could find about it.

This interesting pedal is Top Gear’s most dynamic, and combines both their Fuzz and Treble Boost circuitry into one versatile effect. Even though the pedal is capable of producing an incredibly large palette from which to choose, it is quite accessible, and sounds really good with any combination of control settings. Earlier Top Gear pedals are likened to concurrent better known fuzz pedals, and often draw inspiration from such simple circuitry, however, this circuit is completely unique to the Fuzz Sustain, and while it is similar to other late-’70s Colorsound and Eurotec models, there are significant differences. UK-made Top Gear pedals are inherently rare, and rarely are they available.

There was a request to trace it and create a layout.
