The RhPf Tone Maps have found a new home, and this time, itβs not just a mention.
Pedalboard.org, one of Germanyβs largest online communities for guitar and pedal enthusiasts, has just taken things a step further. They have created a permanent section on their website dedicated entirely to the Tone Maps.
A Shared Love for Pedals and Curiosity
The new page, titled Frequenzgang von Effektpedalen, invites users to explore the frequency responses of both classic and modern effects. From the ProCo RAT and Klon Centaur to the legendary Arbiter Fuzz, it allows players to see how tone evolves, how EQ curves shift, and how design choices come to life visually. In their own words, the Tone Maps are βinteraktive Diagramme, die zeigen, wie die BΓ€sse abfallen, die Mitten anschwellen und die HΓΆhen funkeln.β
In plain English, it is a tool that helps you see how tone is built rather than just hear it.
Who Pedalboard.org Are
For more than a decade, Pedalboard.org has been a cornerstone of the German guitar scene. What started as a Facebook group gradually grew into one of the most respected gear platforms in Europe. Over the years, the site has become known for its transparency, community spirit, and wealth of shared knowledge.
Today, it continues to connect pedal collectors, DIY builders, and musicians through detailed power lists, schematics, and archives. Now, with the new Tone Maps section, the site expands its mission even further. Behind it all is a team that shares the same spirit that drives the RhPf Nerd Lab: curiosity, precision, and a genuine love for sound.

Why This Means So Much
Seeing the Tone Maps become a permanent fixture on Pedalboard.org feels incredibly special. It means one of the most trusted German-language gear communities now treats the RhPf Nerd Lab as part of its educational resources. We are proud, grateful, and inspired by this addition to the site.
Pedalboard.org reflects exactly what RhPf Electronics stands for: innovation, transparency, and a passion for learning and sharing knowledge.
A heartfelt thank you to Holle and the Pedalboard.org team for their enthusiasm. Weβre honored to be part of a platform that continues to inspire players and builders alike, and we look forward to whatβs next.
