Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Catalinbread SFT is an Ampeg Portaflex flip-top amp-inspired overdrive from Portland, Oregon, replicating the unique tonal character of the SVT-style Ampeg amplifier when driven into warm, harmonically rich overdrive. The SFT captures the distinctive Ampeg warmth, the characteristic deep low-end response, and the natural compression of the Ampeg design when pushed past clean. Effective for both bass and guitar, providing a warm, thick overdrive that differs significantly from both British and Fender amp-inspired designs. Made in Portland by Catalinbread.
The Crazy Tube Circuits Heatseeker is a high-gain preamp and overdrive from the Greek boutique manufacturer, providing the thick, sustained, high-gain distortion character of pushed vintage preamp stages in a boutique pedal format. Covers the gain range from warm crunch through high-gain saturation with the compression and harmonic density of a high-quality tube preamp at full gain. Designed for players seeking boutique-grade high-gain performance with the component quality and refined sound of CTC designs. Made in Greece by Crazy Tube Circuits.
