bass compressor pedals Lusithand Alma MK3 Bass Compressor Pedal

DESCRIPTION - MK3

Optical compression is famously used in studios because it sounds natural and musical. It doesn't have artifacts like pumping or breathing sounds, it doesn't overly squash your signal, and it just gives your overall bass tone a "your-bass-but-better" kind of vibe. It compresses in a fairly transparent and musical way.

The Lusithand Alma compressor is an optical compressor, and its original inspiration is the legendary Diamond Compressor. However, it takes a very Lusithand approach to compression, and now in its third iteration—the Mark 3—it's pretty much the ultimate optical compressor you can get for bass.

For starters, it has four controls that make it super simple to dial in. It has a clean blend and a compression control (which is the point at which the signal starts to compress), it has the output to compensate for volume reduction from compression, and it has multiple compression ratios which go from light and subtle to pretty heavy. Most importantly, it has the Tilt EQ feature, which is frequency-selectable and gives this compressor a super useful twist on the classic optical compression formula.

Tilt EQ is a seemingly simple EQ, but it just sounds really good. It's very cool and musical, it makes all the frequencies sound naturally balanced. Essentially, with Tilt EQ you choose whether you want things below a certain frequency point to sound louder than the highs, but in a very natural-sounding way. If you want brighter, more higher-mid content, turn it one way. If you want lower mids and bigger sound, turn it the other way. Or keep it neutral down the middle.

The MK3 version also adds extra features, most notably the attack switch. This gives you the typical fast attack characteristic of optical compressors, plus an option for a slower attack, which allows more of the initial transients through for a punchier sound, a fairly unusual feature in optical compressors.

It also has a -6dB pad for use at the end of your pedal chain, even with super hot signals. The voltage doubler increases headroom to prevent artifacts or distortion, keeping your playing feeling dynamic.

The build quality reflects Lusithand's commitment to professional-grade pedals. The enclosure is robust enough to handle years of touring, while the components are selected for sonic properties and reliability.

If you've been looking for a great-sounding optical compressor that can be neutral or give you character, the Alma might be the right compressor for your rig.

From Lusithand:

The Alma Compressor MK3, an opto-isolator compressor, is an evolution of it’s predecessor; it retains all the original elements and it adds a few more.

A voltage doubler (internal circuit) doubles the voltage being fed. This makes it possible to have 36v when powering from an 18v supply. The pedal can be run from 9v to 18v (max). The higher voltage operation significantly increases the headroom and prevents unwanted clipping/distortion, caused by hotter signals.
