Overview

Black Rooster Audio‘s guitar amp head emulation meticulously modeled after a very versatile, yet uniquely sounding low wattage amplifier the Black Rooster Audio Cypress TT-15 comes to you at an unbeatable price point: It‘s free! With its no-nonsense approach and only six intuitive controls, the Cypress TT-15 will help to get the job done right away, no matter if you‘re looking for clean through crunchy guitar tones or if you want to achieve biting, distorted lead sounds. We also included a simple 2x12 cabinet simulation that can be bypassed if you prefer other solutions or if you‘re feeding into an external power amp/cabinet stage.

Features

Authentic circuit emulation

Our real time SPICE type component based circuit simulation approach allows to authentically capture the sound and feel of the analog counterpart in all nuances. Every crucial part of the head, including pre- and power amp tube stages, the tone filter and the output transformer have been faithfully modeled and matched.

SSE2 optimized code

DSP operations are pipelined using the SSE2 instruction set. This ensures highest possible performance operation despite very complex computations.

Auto-adjusted oversampling for maximum audio transparency

Aliasing artifacts are efficiently attenuated using a low latency linear phase Dolph-Chebyshev poly-phase design. The oversampling is auto-adjusted to your session‘s sample rate to save valuable CPU power while offering the most transparent sound possible.

HighDPI / Retina support

All our plug-Ins support high pixel density on Mac OSX and Windows to bring you the most enjoyable user experience on high DPI displays. Please refer to your manual to find whether your DAW is HighDPI capable if you‘re working on Windows.

The best in guitar amp emulation, and it's free! by Axel Reolon (2025-10-22)

Absolutely Fantastic Amp Plugin! by Redmalo (2025-10-20)

"The Cypress TT-15 by Black Rooster Audio is an incredible free amp sim that delivers way beyond expectations. It perfectly captures the warmth and character of a real low-wattage tube amp — from clean, dynamic tones to rich, crunchy distortion and screaming leads. The interface is super intuitive with just the right amount of controls, making it quick and fun to dial in great sounds. The built-in 2x12 cabinet simulation also sounds surprisingly good, but it’s great that you can bypass it if you want to use your own IRs or external cab setups. Overall, this plugin is a must-have for any guitarist or producer looking for authentic tube tone without spending a dime. Huge respect to Black Rooster Audio for offering such high-quality craftsmanship for free!"

"It has one of the highest plug & play and versatility factor out there. Capable of creating cool vintage tones without adjusting many parameters. Add you favorite third party IR's and you're ready to cover a lot of ground including bass guitars!!"
