Ok, there's a gig or session and they tell you: "we have a full backline here so don't bring your amps. We have twin channel amps here". You go there and there's a Fender Twin and/or a Roland Jazz Chorus. Nice amps, but not for you. Here's the board for that.

Die Warm Audio ODD Box orientiert sich nicht nur optisch, sondern auch klanglich am beliebten Fulltone OCD Overdrive. Leider musste Fulltone-Inhaber Mike Fuller im letzten Jahr sein Geschäft schließen, was die Preise für Pedale wie den Fulltone OCD auf dem Gebrauchtmarkt steigen lässt. Warm Audio hat sich wiederum in den letzten Jahren einen Namen mit gelungenen Nachbildungen von diversen Pedalen und auch Studioequipment gemacht. Mit dem ODD Overdrive bietet das Unternehmen nun eine verhältnismäßig günstige Alternative zum Original an.

The Warm Audio ODD Box V1 (“ODD” for short) is a hard-clipping, op-amp-based overdrive inspired by an iconic pedalboard staple known for having a “cranked amp” tone. Perfect for boosting, adding breakup, or adding high gain to cleans, the ODD has all the tonal versatility of its inspiration. Delivering all of the sounds of a cranked, saturated tube amp, the ODD features classic-inspired controls, including a UK/US Switch, to flip the personality of ODD from a “British” to an “American” tube amp. True to its inspiration, the ODD delivers the sound of massive, live electric guitar that attracted players like Billy Gibbons, Mark Hoppus, Eric Johnson, J Mascis, Paul Gilbert, and many more to that open tube amp sound.

T-Rex Møller 2 delivers the same classic overdrive that made it's predecessor one of T-Rex’s most sought-after pedals. Named after Danish guitarist Knud Møller, for whom the original pedal was designed, Møller 2 features a more durable “Bass Boost” toggle switch and easier-to-read control knob graphics. The pedal is armed with a 0-20 db clean boost, as well as a mix control which lets you dial in the perfect balance between distorted and clean signals. Rolled all the way up and with distortion maxed, the pedal sounds just like a vintage tube amp at full volume. Roll the Mix knob back a bit, and your clean signal starts to get through; if you pick lightly or roll back your guitar volume, you get a stunning clean, softly-clipping sound that retains all the feel and dynamics of your original tone, only bigger, louder and richer. The boost function lets you dial in a solo level, whether the overdrive circuit is activated or not.
