It'snotgreat asaclean/invisiblepeaklimiter,becausethe effectisso

limitbigpeaksjustfine. Becausethereleasetimeissovariableand
dependent onthe signalpassing through, the amount eachnewnote's
first peakwillbe compressed can change dramatically.So you'llget the
smoothest, mostconsistent action byplaying smoothlyand consistently,
with fewlong rests.
Aside fromthe ratioswitch,ithasonlytwocontrols:threshold(labeled
"peakreduction")and outputgain.Thereisnolight to indicate when
you'vecrossedthethreshold. Whilethe controlsareverylimited, the
good newsisthatthe range ofthe peakreduction controlisquitewide,
andcapableof awiderange of flavorsand effects.It justtakessome
timeand experimentation to find the flavorthat willworkbestforyou. It
doesseemtogetinto aheavier-squashing range fairlyquickly:playing
abasswith "average"output levels,itseemed tocrossthe threshold
quiteoften, with the peakreduction knob at around9:00. Soifyou want
morerangeof light/subtleaction,youmayneed to reducethe levelof
the signalyou feedinto thispedal.
Thereisno loss ofhighsorlows,although both high and lowendcan
soundabitcongested orattenuatedduringmomentsof heavy
squeezing. Mostof thetimeit'snot an issue, plentyofhighsand lows.
Infactatlight settingsthelowsseemto notget compressedasmuch
themidsand highs;thiscan be aprooracon depending onyour
expectations:at alowratioandhighthreshold,thelowfrequenciesare
simplymassive,whichsoundsfantasticbut mayresultinclipping of

transparent, butit'sjustcoloredenough to "haveatone",and to

strongercomp settings.
It'sinthe same"medium"sizeastheBarber,Diamond,and BBE
pedals.Theconstruction isclean andsolid,andthe footswitchisa
relay-basedtrue bypass (myfavorite kind of bypass).It runsona
12VDC,1.5Awallwartpowersupply;itwillnot be poweredbyany
daisy chainorbrick-type supply.
Comparing itagainst some othertube comps:
The Markbassismuchmorecontrollable,andlessexpensive,but it's
muchlarger.The Markbass can squashasheavily,butitdoesn'thave
the funkydip/swell;otherwise, their tone isequivalent.
The Retrospecismoreversatile(DI,EQ, preamp),butit'salot larger,
and also harderto find.TheRetrospeccolorsthe tonemore.
The Voxismuchcheaper,and itcando the samesortof extrasquashy
effect, butisnot capableof the "unobtrusive"ornearly-transparent
tone oraction the Effectrode canachieve.It'smuchlarger,but on the
otherhandit doesn'trequirea specialpowersupply.
The mostdirectcomparison wouldbeto theCAE V-Comp, butit'sbeen
averylong timesinceI'veused thatone, somycomment heremaynot
beaccurate.Iintend togetanotherV-Compsometimesoon. My
recollection,however,wasthattheV-Compwasn'tquite asversatile,
andwasa bitnoisier.
Allinall,ifyouareinthe market fora"high end"tubecompinpedal
