Jule Monique All Tube Bass Preamplifier by Jake Wolf
Jule Monique All Tube Bass Preamplifier by Jake Wolf…ย When I first unearthed the Jule Monique from its shipping box, I wasnโt sure what I was getting in to. ย ย At first inspection, it appears gorgeous; a bamboo wrapped, cleanly executed tube-laden symphony of quality components and luxury fit/finish.ย Then, as my wheels of practicality and pragmatism started turning,ย I started looking at this sizeable, relatively expensive, preamp-only device, and I couldnโt help but wonder if, with todayโs cornucopia of great sounding micro heads and stompbox preamp/DIโs, is there really a niche/need for this beast?ย Iโve played through and owned a lot of tube preamps over the years, in my quest for bass tone nirvana.ย On the whole Iโm a big fan of the warmth and textural depth that tube circuits often bring out in my sound.ย ย ย As I waited for the Moniqueโs tubes to warm up for an initial listen as the front end of my rig, I was thinking; โThis thing better really bring the heatโ. After about 2 minutes of testing, it was evident that Monique might just be the pinnacle of impeccable, studio-grade tube tone for the bass world.
Monique was designed as both a studio direct box and a tube front end for live rigs, in the spirit of classic bass heads like the mighty Ampeg SVT.ย With Moniqueโs huge and defined tone, super low noise floor and powerful EQ, she excels at both. While many bassists covet the tone of their all tube heads, they rarely covet the size and weight that accompany it.ย As many working proโs find themselves flying all over the map to gigs and sessions, one can see how having a portable device that can offer similar tone and feel to their beloved tube head is becoming increasingly practical and desirable.
The front panel of the Monique is simple and effective.ย A knob labeled โLine Levelโ acts as a master volume control for the ยผโ output, and a powerful 3 band โBaxandall-styleโ EQ allows for broad tone shaping with 20db of cut/boost per band.ย ย The โsensitivityโ knob is where things get interesting.ย As you turn the knob clockwise from zero, as Jule puts it, โYou hear more from Moniqueโ.ย ย Set closer to zero, Monique sounds clean and precise.ย The more you crank it up, the more grit and growl comes out of the unit, and the more dynamically expressive it becomes.ย Dimed, it definitely starts to resemble an overdriven tube amp.ย Additionally, the Sensitivity knob has a pull function that adds 4 db of headroom, designed to optimize its use with passive basses.ย The rear panel features two discrete outputs: The ยผโ unbalanced output is intended to drive the front end of an amp, but I found it will also adequately drive a poweramp (or for that matter, an effects return/power amp input on a bass head).ย The transformer driven XLR output level is set by the volume knob on the rear panel.

The Jule Monique is available in bamboo for $1700, or with a metal frame for $1300, sold direct from the builder, Jule Potter of Jule amps.ย In his small California workshop, he hand crafts a luscious array of boutique amps and preamps. Check him out online at www.juleamps.com.
