Teisco Analog Vintage Preamp Boost: 9V-24V internal gain


Add to Cart
We are excited to introduce the emphatic return of Teisco! That lovable quirky brand from the 60's is back with the same funky vibe, and a great new line of analog effects pedals. The Vintage Preamp Boost is one of three flagship circuits that offers super clean FET boosting capabilities combined with shape-able EQ, and an internal voltage switch that allows you to run the gain at 9 or 24 volts with only a 9V power supply!

The Teisco Boost is a simple and effective platform that can enhance your tone in a variety of ways. It's modeled after a vintage preamp and using a Field Effect Transistor-based circuit it gives you up to 30dB of clean boost and warm, organic clipping. It's more than just Level and Gain though, the Teisco Boost also features 3-way EQ shaping switch and an internal voltage divider to boost the circuit to 24V for huge clean headroom even a maximum gain settings. These options make it easy to dial in your sound whether you need a clean push, dirty lead tones or a world class signal buffer. From the stage to the studio, this could be your next secret ingredient.
