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.

Great amp... by manuel lopez (2025-10-11)

No tweaking marathon required by John (2025-10-11)

"Honestly didn’t expect much from a free amp sim… but this thing growls. It nails that chewy Orange tone without the fizz, and reacts to pedals like a real tube head. Dropped it on a track and instantly got that wall-of-sound vibe! No tweaking marathon required!"

Great little amp by MIke (2025-10-11)

"I've used this on a handful of guitar covers (Black Sabbath, The Sword, etc) since it's easy to dial-in in a pinch. Just gotta pair it with the right IR and you're golden. "

5
It sounds "orange"! by Mirko (2025-10-11)

"Cypress has been available for free for several years. There are similar plugins, but this amp just sounds right. It works great with both digital and analog pedals. I sometimes use it to add a little extra flair to other sounds. I don't use the cabinet section, but that's a matter of taste. From jamming to quickly recording something to production, this plugin is a must-have!"

5

Great plugin, also simple and easy to use! by ForzaSans (2025-10-11)

"This has become a versatile guitar amp plugin for me, I use this for mixing guitars in cinematic scores or rock (sometimes). Moreover, the plugin is simple and easy to use, produces a good tone, and is suitable for rock if you want to make a rock song. The best part? It's free!"

5
Minimalist bass and guitar amp by Mark Dancer (2025-10-10)

"Only a few controls (based on an Orange Tiny Terror), but enough to dial in a great sound, particularly at the lower gain settlings. Designed for guitar, but also works well on bass."

5
Great little sim by Jordan O (2025-10-10)

"Quick and easy amp sim. Sometimes it's the simple one that gets the job done best. I like that I can set it up in no time, and the visual element is a nice touch. Feels like using a real little amp without the fuss."

Cypress TT-15 - Good juju! by Cliff Ziarno (2025-10-09)

"Love the Black Rooster plugs. Very simple and sound really good. Having a bunch of knobs doesn't mean value. Well done..."

5
Cypress TT-15 by JC S (2025-10-09)

"It only has a few knobs and options but I find this amp to be a perfect platform for carving your sound. The sonic flexibility around it is made possible by the fact that the Cypress TT-15 is very easy to work with if you want to integrate it into a more complex signal chain. It has the tonal caracteristics of the amps it is modeled after. As far as I'm concerned, it is the closest a plugin has been to sounding like my Orange Dark Terror. A delight really."

5
Rock on! by Steve C (2025-10-09)

"Minimal tweaking needed to get you rocking with this one. Just a good clean distortion(?) that takes you back to the days of cranking it up down the basement."

Very Nice Tiny Terror Emulation by Angie Angel (2025-10-09)

"One of the best sounding Tiny Terror emulations I tried so far. Clear recommendation!"

5
Easy tones by Chris (2025-10-09)

Nice amp sim by JB (2025-10-09)

5
it’s really close to the real Orange Amp by Fabrizio (2025-10-09)

"I love the creamy sound on guitars. This is one of the most realistic emulation of the Orange Sound. Amazing!"

5
Excelente emulación!! by Isaias (2025-10-08)

Tiny Terror by AlpacArtist (2025-10-08)

"I often use it with my bass D.I. to replicate my Orange amplifier, with devastating similarity."

Love it by masademar (2025-10-08)

"No soy guitarrista, pero cuando uso samples de guitarra, este es el ampli que uso y que me da más realismo. Es muy liviano para la CPU y realmente suena bien."

Did you say "amp sims are trash?" by Ken B (2025-10-08)

"well...some of them are. Actually a lot of them can tend toward the plastic sheen sound aesthetic, creating dirty artifacts and overblown gain modes. Not the Cypress, it's creeeeaaamy. At least the way I'm using it at the moment it is. Running a di'd guitar signal into it, you would imagine there would be the usual un-inspiring notched out fizzy fart fest to contend with...nope! The Cypress gain runs like actual amp gain, in fact it does it so well we ran a bunch of pedals, pre di, into the desk to try and break the gain characteristics...we failed. Ok, so it handles pedals, so what? Well, recently a client arrived with his favourite head (Orange 50) in disrepair, and basically cooked. He was upset and having a hard time getting into the groove of the performance. I ran to the iso booth and pretended to mess about with a similar amp to his with the guise that we could make it work. Secretly I did nothing, except maybe scratch my butt. At the desk I loaded up the Cypress on a separate monitor window and full 11'd the volume and started slowly raising the gain while he noodled in despair. After 10 or so seconds he asked if I'd magically fixed his amp. I said nothing and carried on. 45 minutes later and two new tracks complete he asked if he could borrow the amp until his got fixed. I said sure and sent the link to his phone! Speechless was that man! So a very precious lead guitarist was fooled into assuming either I'm an amp wizard or I have a plethora of boutiques sat in my cupboard (I don't) to the point he wanted to gig it. The Cypress has now appeared on 5 other separate band recordings, all with the same great reception, and I'm going to keep doing it...Nuff said. Oh, and it's FREE!"

This thing actually *smokes!* by Giselle Chacon (2025-08-21)

"I actually hate amp sims. They always leave me missing the interaction of a real speaker and amp in the room with me. But there are a lot of times mixing and producing that you need a great amp sim. The problem is most of them are too fizzy, to fake. Great classic rock guitar tones are simple and pretty clean. Listen to ACDC again. Cypress is great because its simple but it sounds great. Nice sorta 'ducky' British citrus tone but best of all it really sounds like a tube amp. If you run at -18dBu on the console pad the input another -6dB for more headroom ;) Thanks BRA team, you rock! And its FREE!! 5 stars twice. :O"

Amp Sims by Michael James (2025-10-09)

"I like this amp sim. I have an Rockerverb MkII that I couldn’t really turn on because it’s 100 watts and I have kids now. This gets me really close to the sound I have in my head. "

Amp sims by Michael Campos (2025-10-09)

"I have an old orange 100 watts Rockerverb MkII that I can’t really crank anymore. This amp does a good job of getting me to that sound in my head. I wish there was a clean sound too but that’s alright because it’s free!"

So Simple, So Good by JerryG (2025-03-17)

"Most everyone should know what amp this plugin is emulating, and it does it damn well. I record raw (black metal) and this is so good, it is now the only plugin I need for the tone I want."

Great by Hotmitts (2025-01-29)

"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!!"
