Der Heliodor Amp Overdrive ist ein DIY-Overdrive-Projekt, das auf der klassischen BOSS OD-3 Overdrive-Schaltung basiert und für eine true bypass-Funktion adaptiert wurde. Er nutzt eine diskrete JFET-Op-Amp-Topologie, um einen sanften, amp-artigen natürlichen Gain- und Dynamikumfang zu erzeugen, der sich für geringere bis mittlere Overdrive-Töne eignet. Das Design behält die Kerncharakteristiken des Originals bei und verfügt über Regler für Drive, Tone und Lautstärke zur Klangformung.

The Heliodor Amp Overdrive is a DIY overdrive project based on the classic BOSS OD-3 Overdrive circuit adapted for true bypass operation. It uses a discrete op-amp JFET topology to create smooth amp-like natural gain and dynamic response suitable for low-to-mid overdrive tones. The design retains the core characteristics of the original with controls for drive, tone, and output volume to shape the effect.

The Cerulean Amp Overdrive is an updated version of the Marshall Bluesbreaker pedal, in production from 1991 to 1999. A legend in its own right, it was also the source circuit for a number of expensive boutique pedals, most notably the Analogman King of Tone, which is two Bluesbreakers in the same box with a few modifications.

In 1995, Marshall moved production from England to Korea, and around this time they made some tweaks to the circuit, increasing the gain and reducing the bass. The Cerulean project has a switch to go between both modes so you can hear the differences. It also borrows the expanded clipping options from the King of Tone, allowing you to select either soft clipping (stock), hard clipping, or no clipping (boost mode).

Cerulean Amp Overdrive / Marshall Bluesbreaker

The Azure Analog Chorus is based on the BOSS® CE-2, first released in 1979 and generally considered to be one of the best chorus pedals ever made. With only two knobs, it’s simple to operate, but it doesn’t take long to understand the wide range of sounds contained inside.

Azure Analog Chorus

Der Andromeda Natural Overdrive ist eine Nachbildung des Nobels ODR-1, eines etwas obskuren Pedals aus Deutschland, das unter Studiomusikern in Nashville als „Geheimwaffe“ gilt.

Die überwältigende Beschwerde über den ODR-1 ist, dass er viel zu viel Bass hat, ohne dass man ihn herausdrehen kann. Zu diesem Zweck enthält der Andromeda einen variablen Bassregler, der vom Timmy und Zendrive inspiriert wurde. Die Standardtöne sind immer noch da, wenn der Regler ganz aufgedreht ist, aber jetzt haben Sie die Möglichkeit, ihn zurückzudrehen.

The Andromeda Natural Overdrive is a recreation of the Nobels ODR-1, a somewhat obscure pedal from Germany that nonetheless is considered a “secret weapon” among Nashville studio musicians.

The overwhelming complaint of the ODR-1 is that it has way too much bass with no way to dial it out. To that end, the Andromeda incorporates a variable bass control inspired by the Timmy and Zendrive. The stock tones are still there with the knob all the way up, but now you have the option to dial it back.

Manual

Andromeda

A part-for-part replica of a mythical overdrive effect noted for its high-end tone and price. The Klon Centaur and its successor, the KTR, remain highly original designs in an industry full of clones and tweaks to existing circuits.
