does it have a dial under the 2v led? my friend has the eqx and i had the eqt's they work as line drivers..thing to remember is even though they can get "8 v" (believe they say high as 13)is that they prolly wont lol most i could get to boost cleanly was 5.5 volts from 3.9v then i got smart and used an amp as a line driver lol
