This effect is a complex spectral saturation processor simulating a set of different analog gear in a new and unique way. Benefits of this algorithm is that it is highly CPU efficient and adds (almost) no latency.

The 7 models available are based on real analog gear individually measured in two dimensions; gain responses (-inf dB to +6 dB) at the frequency spectrum 20Hz to 20kHz. This data is used to transform input audio to output audio.


Cassette Deck

A consumer cassette deck produced in the mid 80’s. This profile adds some nice grit in the lower mids and rolls off the higher spectrum in a very pleasant way.

1/4” Tape Reel

A high quality tape reel machine was used for this profile. Set to one channel mode, there was plenty of dynamic bandwidth to capture on this one. Adds some subtle tape saturation that oozes mid 70’s.

Preamp Tube Clean / Preamp Tube Drive

These two profiles are captured from a high end tube microphone preamp with two different input gain levels (normal gain on the Clean version and a boosted level on the Drive version). Used on only one channel, this profile is very subtle, but the impact adds up when several channels are used simultaneously.

Guitar Tube Clean / Guitar Tube Drive

The guitar amp used is a well known pro amp used by several pro guitar players, and Just like the Preamp Tube profiles, these are recorded with two different input gain levels.

Tube Bass Amp

One of the developers friends dad had an old bass amplifier that we borrowed and profiled. Tip: Run a Fender Jazz bass through it and your neo soul licks will sound just like they’re supposed to.


Since there are several models available, this one can be used on almost any type of audio in any genre. The output can span from lo-fi to high-end hifi. One approach is to put it on several tracks with a more subtle setting which makes the essence of the gear simulated add upp. Another is to put it on the mix, or a bus.

Since we’re in the digital domain there can be some added aliasing when distorting the signal too much, resulting in an unpleasant high frequency boost. To prevent this, set the HARMONICS switch to SOME or FEW.

Digital saturation that doesn’t “sound digital”

I’m about as bored as I could be with glitch-based digital distortion and saturation that seems to rely solely on spiking the signal, filling the room with noisy pops. Although I don’t necessarily need my digital gear to sound like analog gear, I do like smoothness and musicality sometimes. This app delivers sweet overdrive and saturation without putting the whole sound spectrum through a cheese grater, adding depth without destroying harmonic character. So nice! I haven’t plugged a guitar into it yet, but it sounds awesome on synths and samples. Versatile enough to make just about anything sound better, it has a place in almost every mix now. Almost as indispensable as a compressor!

Another Klevgrand, another hit

Literally just bought several overdrive apps yesterday searching for an AU guitar solution that didn't sound crappy. I came away unhappy. Then today, Klevgrand releases another top quality app that fits my needs for an overdriven DI guitar perfectly, and then is capable of doing even more. I don't know what's gotten into them since Brusfri, but the professional quality of their apps has jumped through the roof...they're all must-buys.

Unbelievably amazing tone. I wanted a simple and great guitar tone without all the millions of options and effects from other apps. Plugged in and played for hours because I couldn’t get over how good it sounded.
