Just got a brand new Pigtronix
and first thoughts where its awfull, totally squashed and strangled all life out of the bass.
put it back in box to send back.
then i read instructions (doh) turns out i was using it all wrong, firstly plugged it into 9v rather than 18v (double doh) it will work at 9v but not properly, then i realised this is the first compressor that actually does what a compressor is meant to do and was not using it for what i want.
now i get it and after a bit of playing around got exactly what i wanted from it. Set the volume to match at unity with amp, had compression set at about 10 o clock, sustain at 8 o clock. And bingo, got a rounder more defined sound a little cleaner volume boost and slightly thicker warmer sound without loss if tone and more note definition its only subtle but noticeable. Had to increase compression to around 11-12 when using more heavy Fuzz. Finally got what i want and finally get it. Think most of the other ones i have had are not trully compressors. This actually does what a compressor is meant to do.
