COLORSOUND: Treble Booster, Steve Williams (partial trace)

Colorsound treble booster SW v1a 63b78e94114f

So there are a few bits missing, but if you are familiar with treble boosters, I’m sure you’ll work it out.  Being a small and simple circuit, it’s a good candidate for breadboarding. The filter pot is your standard input blend, probably similar to the values that Steve Williams uses in his Pigdog Competition Special … Read more

COLORSOUND: 1971 Overdriver

COLORSOUND Overdriver vero layout v1 5be53da30ae0

The Colorsound Overdriver / Power Boost family went through a few different versions over the years. This layout is for the classic 1971 9V Overdriver version – essentially the 9V successor to the earlier 18V Power Boost, with the same basic three–transistor topology but set up for a standard single-supply pedalboard. It makes a huge, … Read more

Germanium Variable Booster

Variable booster NPN GE v1 83641fd42195

Nothing groundbreaking today—just a variable-gain germanium booster I through together this afternoon, heavily inspired by the D*A*M Red Rooster. I built mine on a slightly different layout, but if I do another one I’ll use this version; it’s cleaner and a bit easier to wire.  And if you like the idea of incorporating a trim … Read more

R2R ELECTRIC: Germanium Pre-amp

R2R electric germanium preamp layout v1a 7a010453327e

It’s no secret as to what the R2R Electric germanium preamp is based upon, which is an old and very rare Hofner preamp.  The Hofner is a full-range germanium booster, which was once used as a way to plug guitars into old console radios way back in the day. As this is a simple Rangemaster style … Read more

FENDER MDX Circuit / AION FX Elite boost / preamp

FENDER MDX Aion Elite vero layout v1 f7656c17a1fa

There’s a few variations of this circuit, so I’d recommend reading through the Aion FX build docs or maybe just skip the vero all together and buy the board from them. The build docs also include LTspice simulations of the frequency response, so that saves me a bit of time plotting them out. I’ve labelled a … Read more

Thorpy FX The Dane

Thorpy FX The Dane 63908e63dd19

As requested on the forum, this is the original version of The Dane based on schematics found on one of the effect PCB sites.  A Drive only version was requested so I’ve done this on two separate boards for Drive and Boost, each with their own independant supply filtering and Vref components.  If you want to build the whole thing you can either do it on two boards as shown, or it should be easy to adapt to a single board, and you could even potentially make them a bit smaller by removing the duplicated filtering and Vref parts.

Info about the original:

Here’s what Peter Honoré himself says about The Dane Overdrive and Boost pedal

“I love Thorpy pedals! They look awesome and they sound amazing. I wanted to create something that would cover all the gain that tones I use, from clean tones with massive headroom to awesome bluesy lead sounds. After playing the Gunshot and the Peacekeeper I asked Thorpy if he could come up with something that would be able to do what I wanted and he said yes…. Enter “The Dane” Drive and boost. It’s not high gain. It’s a clean, expressive and dynamic overdrive. The boost has got a “Low” knob which will make your singlecoils sound super fat which I love. We also made it smaller, so now it has the same footprint as most two button pedals. Easy to get on your pedalboard. Well, what are you waiting for?”

The Dane pedal is a brand new overdrive and boost from Thorpy FX designed specifically for Peter Honore from our Andertons TV Youtube channel.
From the ground up

This pedal was designed from the ground up by Thorpy FX after being approached by Pete. The Dane doesn’t have quite as much gain as the Gunshot but has been made to allow the nuances of your guitar playing to come through the amp. It’s incredibly expressive and importantly, easy-to-use.

It’s one of those pedals that you can just plug in and easily get a great sound. The boost and the overdrive channel can both be used on their own to great effect, but the pedal really shines when you drive the Overdrive Channel with the Boost channel for bluesy tones with plenty of sustain.
Controls

    Boost – This controls the volume of the boost and how hard it will drive the Overdrive channel which is next in the signal chain.
    Lows – These will fatten up the low-end of your guitar. Particularly good for making Single Coils sound fatter than before.
    Tone – This controls the overall EQ output of the pedal.
    Volume – This controls the volume of the drive.
    Drive – This controls the gain you’ll get from the pedal. If you keep the gain down and volume up, you’ll have more headroom. If you keep the volume down and the gain up, you’ll have more dirt! Set it to taste.

HOFNER: Germanium Pre-amp

Screenshot 2023 07 25 at 6.27.53 pm b127fb1c0943

I only came across the Hofner Preamp quite recently, despite seeing some other builders making point-to-point style germanium preamps based on this circuit – the prime example being the R2R Electric preamp. There’s a good write up here, but in summary: Back in the day before guitar amps were affordable, and TV was a thing, … Read more
