What Do AM Effects Say?

I wanted to celebrate the creation of my 10th pedal, so I made a special version featuring a high-spec, British-made Mullard OC45 transistor, along with a red LED - the same as in the very first pedal I built.

The Germanium Treble Booster is my personal take on the classic, positive-ground Rangemaster Treble Booster circuit. Each pedal is built around carefully selected vintage germanium transistors, meticulously tested to meet strict specifications for gain, leakage, and noise.

While the tonal heart of the circuit stays true to the original design, I’ve made a few enhancements to improve reliability: additional power filtering ensures low noise levels when used with an isolated power supply, and anti-pop resistors eliminate unwanted noise when the pedal is engaged.

All of this comes housed in a compact 1590B enclosure - perfect for saving valuable space on your pedalboard. Whether you're chasing the iconic tones of the ’60s or looking to add character to a modern setup, this pedal delivers a dynamic response and warm overdrive tones that cut through the mix beautifully.

When placed first in your signal chain, it cleans up gracefully with your guitar's volume knob and can push a cranked amp to a whole new level.

Monorail for Patch Cables

Good service. If you know monorail, you will know it’s more expensive than it should be. I found it the cheapest at Pedal Jungle.

Hi Zak. Thanks for the purchase and review mate. Paul

Dark Star & Dark Fuzz

OBNE Dark Star is as good as you'd expect, and looks stunning in the black finish. The Dark Fuzz coffee is just as dark and brooding, perfect to pick you right up in the morning. Both were delivered with the usual care and attention to detail from Pedal Jungle and both highly recommended!

Hey Chris, thanks so much once again mate for your continued custom and support. Enjoy the coffee! cheers, Paul

Amazing pedal and great service

Delighted to be able to support the independents.

Hey Leon, our pleasure mate, and thanks so much for the purchase and taking the time to review. Paul

Beetronics Larva - Morphing Phaser

A phaser pedal with double the bang for its buck. The ability to ramp up or down at the press of a foot switch makes this one of the most versatile phasers out there.
Thanks to Paul and Sian for the excellent customer service after a slight delay on shipping from their supplier. Service that will keep me coming back for more.

Thanks for the purchase and review mate, always appreciated. Paul

The Secret Setup Blueprint

Approaching any pedal board build can be tricky so having something to trigger some thought about pedal placement and gear was insightful and helpful for my own recent, personal board setup.

Thanks Alan. Awesome that you enjoyed the book and got something out of it mate. Thanks again, Paul.

Secret Setup Blueprint

This ebook is just great. Whether your new to effects pedals or have a keen passion for them you need to take a look at this. Interviews from the top leading pedal builders and lots of useful information to get you started or trying something you’ve not tried before. This book is a must have.

Thanks David. Glad you enjoyed the book and cheers for the review! Paul
