VST3-Plugin Bundle Live in 1979

MK-Guitar.com Vintage Plugin Collection

VST3 plugins for Windows (support for other operating systems and additional plugin formats planned).

All six plugins are also available separately.

Some guitar sounds keep us listening for a lifetime. The touch, the phrasing, the way a note blooms and hangs in the air—we learn to hear more in them as our own playing develops. And the closer we listen, the more the small details matter.

The MK-Guitar.com Vintage Plugin Collection grew out of that same journey: playing, listening, and looking more closely at the equipment behind the sounds we love. Its development brought together careful research, measurements of authentic vintage hardware, investigation of circuits and components, and countless comparisons by ear.

With so many plugins available, why make more? Because sometimes the sound we are searching for is the perfectly imperfect one. A little distortion, a particular softness in the repeats, or the faint breathing of an old circuit can contribute something musically valuable. These details helped shape the character of equipment once found between a guitar and its amplifier, on concert stages, and at live mixing desks.

The six plugins in this collection focus on effects that can become part of your everyday guitar sound. Compression shapes the response and balances the notes. Delay adds richness and depth. Spring reverb gives the sound space, width and a sense of being in a room. Dynamic treble control gently tames the notes that bite too hard.

Each effect offers a different part of that experience, with the same purpose: to help you find a sound that responds to your touch and makes you want to keep playing.

The six plugins included

1. Orange Juicer Compressor

   The Orange Juicer Compressor brings vintage compression to your guitar recordings. It gently controls louder notes, brings quieter details forward and adds sustain, helping fingerstyle passages and melodic lines sound more balanced and connected.

   Developed through measurements and listening comparisons with original vintage hardware, it captures the distinctive response and subtle coloration that make this kind of compressor part of the tone itself. Your touch still shapes the performance—with a little extra support for every note.

2. Green Analog Delay

   The Green Analog Delay adds depth and richness to your guitar sound, from subtle echoes that blend into the notes to create a thicker, warmer guitar tone. Its progressively darkening repeats leave room for your playing while adding a sense of warmth and space.

   Developed through measurements and listening comparisons with original vintage hardware, it captures the filtering, feedback behaviour and small imperfections that give analog delay its character. Mark Knopfler used such a device on stage to thicken his guitar sound (not to produce long echoes, this was done with tape delays).

3. Alchemist Spring Reverb

   The Alchemist Spring Reverb surrounds your guitar with a rich stereo spring ambience. It adds depth and a lingering sense of space, helping a close, dry recording feel more open and inviting.

   Inspired by vintage multi-spring studio reverbs—like the one that Mark Knopfler put into his new stage effect rack in 1980—its multiple simulated spring paths combine into a textured, spacious sound, without the unwanted “clustering” of simpler spring reverbs. Shape the reverb’s tone to complement your guitar, from a subtle background glow to a more enveloping atmosphere with its own distinctive character.

4. Guitar De-Piercer

   The Guitar De-Piercer softens harsh, piercing treble when it becomes too prominent—a regular problem of bright clean guitar lead sounds. Unlike a fixed treble cut, it responds dynamically, helping you retain the brightness and detail of your guitar while controlling notes and attacks that sound too sharp.

   Choose Absolute mode to target stronger treble peaks, or Relative mode to respond to the balance of treble within your sound—even in quieter passages. It is a useful finishing touch when you like your guitar tone but want it to feel smoother and more comfortable to listen to. Using a device like this was a “secret” of many top sound engineers, and was seen both in recording studios and in live effect racks.

5. Simple Space Delay

   The Simple Space Delay adds spacious, tape-inspired echoes to your guitar sound. Use it to give melodic lines more depth, let sustained notes linger, or add rhythmic movement to a phrase.

   Place the echoes independently in the stereo panorama and soften their treble to help them sit naturally behind your playing. Inspired by the longer echoes heard in classic live guitar mixes, it offers a straightforward way to make a recording feel wider and more atmospheric.

6. 79 Spring Reverb

   The 79 Spring Reverb brings distinctive vintage spring ambience to your guitar. It gives dry notes room to breathe and adds a lively, lingering texture that complements expressive picking, melodic lines and sustained chords.

   Developed from measured spring-reverb behaviour and careful listening, its eight simulated spring paths create an atmospheric sound inspired by classic late-1970s live guitar tones, where such a device was used in the mixing desk of the PA system. Simple tone and mix controls make it easy to find the amount of space that brings your playing to life.
