The BLOOM from Jackson Audio is a comprehensive dynamic engine that is designed to give guitarists maximum dynamic tonal control in ways never before possible. The BLOOM v2 – MIDI takes everything people love about our original BLOOM and updates it with MIDI!

The BLOOM v2 – MIDI now offers MIDI control over all 6 compression settings, circuit ON/OFF (COMP, EQ, BLOOM) and bloom level; the bloom level can also be expressed via MIDI!

A three-fold device, the Bloom manipulates the dynamics of the instrument by way of precisely tuned optical compression, equalization, boost and sustain circuits which can be activated separately or in tandem with each other.
 
COMPRESSOR OVERVIEW
 
As a compressor, the Bloom features an optical limiting circuit that takes its inspiration from compressors designed during the golden age of vacuum tube circuits. Optical compressors as they are called, are known for their transparency and subtlety. While the Bloom can provide a very aggressive response at more extreme compression settings, its real strength lies in its ability to add a gentle sweetening and roundness to the tone as the optical circuit works to polish off any rough edges in the sound.
Because of its natural and touch responsive bloom, the Bloom is ideal for players who typically don’t use compression but want the ‘mastered’ response that optical compression gives a guitarists tone.
 
The frequency response of the compressor section is flat as a board and does not boost or cut any of your highs or lows. In fact for the demo videos we recorded, Dow Tomlin (Bass Player for Wynonna Judd) used the Bloom on his bass the entire time and loved it! Just like a well-designed compressor should, the Bloom alters the dynamics of the guitar signal and not the tone. A good compressor should be felt and not heard.
 
DUAL COMPRESSION – AKA SLIDE MODE
 
During the design phase of the Bloom we consulted with slide master Joey Landreth, of The Brothers Landreth fame, on what an ideal compressor for guitarists as well as slide players would be. After going back and forth with him it soon became clear that to build the ultimate compressor for guitarists we would have to include the option to run two compressors in series with each other to provide the legendary Lowell George slide tone. Lowell George, the bandleader/singer/songwriter/guitarist for the band Little Feat was famous for using two Urei 1176 compressors in series with each other to give his guitar near-infinite sustain while still remaining crystal clean.
 
When set to compression preset 5 or “Slide Mode” the aux compressor circuit is activated and placed in series ahead of the primary compressor. The tonal result of using two compressors in series is that notes will sustain almost endlessly and oftentimes break out into harmonic feedback while still remaining clear and clean! It ‘feels’ like you have an overdrive pedal on but the tone is still clean with endless sustain!
Hidden inside the Bloom, is an auxiliary compressor circuit that is identical to the main compressor circuit however without externally mounted controls. This aux compressor, which is set with a fast attack of 7.5ms, has two trimmers mounted on the right side of the pedal and are accessible when the cover is removed. These trimmers allow you to adjust the COMP and VOLUME settings of the aux compressor when using compression presets 5 and 6.
 
CLEAN BLEND
 
When more subtlety is desired from the compression circuit, we have included a BLEND control that allows the player to blend in their clean, unaffected signal back in with the compressed signal. One of the best features of the Blend control is that it allows the player to dial in a really aggressive compression setting and then blend some of their clean signal back in with it. This produces the effect of giving the note a very natural attack while slowly fading in the sustain that comes from running a high compression setting.
 
MIDI – NEW FOR 2019!
 
Since the BLOOM first came out, we have received many requests from our players saying that adding MIDI to the BLOOM would make it the perfect compressor and we completely agree! Always we take player feedback as a primary driver of product development and we are very proud to announce that the most flexible compressor on the just got better with the addition of MIDI! NOTE: In order to accommodate this new feature, for space reasons, we were required to eliminate the SIDECHAIN that the original BLOOM featured.
 
3 BAND EQUALIZER OVERVIEW
 
The EQ circuit features a studio-grade EQ that gives tremendous tonal flexibility to the BLOOM. Based on the legendary Baxandall EQ that is featured in countless studio EQ’s, the Bloom EQ takes this circuit and tailors it for guitarists! We spent tons of time on this EQ dialing it in so it would hit all the frequencies that guitarists need to adjust and then sweetened it by removing the ear fatiguing highs and lows that can appear at extreme settings.
 
EQUALIZER CIRCUIT FEATURES:
 
Studio-grade EQ with High Bandwidth and Flat Response at 12:00
+/- 12dB Boost/Cut per control
Center Detents on the pots that make it easier to get back to a neutral or flat response.
 
BLOOM OVERVIEW
 
The Bloom circuit is one of the most exciting parts of the Bloom! Designed as both a level booster and sustainer, the Bloom can work as a set boost by quickly pressing and releasing the Bloom footswitch, or by pressing and holding the Bloom footswitch, the Bloom circuit will slowly ramp up the level to the level set by the boost. This ramp-up time, which is programmable, can be used to increase sustain on held notes or to match the dynamics in a song. Once the ramp-up is complete, pressing and holding the Bloom footswitch again will fade the level back down to unity.
 
BLOOM CIRCUIT FEATURES:
 
0-20dB Boost Available (quick press on Bloom footswitch)
0-20dB Bloom Available (long press on Bloom footswitch)
True Boost Circuit. Fully counter-clockwise position is unity level.
Totally flat EQ down to sub-audio frequencies.
Programmable Ramp Up/Down Time.
