[littlelabs]

If the STD was new give it a couple days use, it will warm up after a short period of break in. This isn't audiofool mojo it's just a new electrolytic cap takes a lil time to polarize correctly. I break in all the other littlelabs stuff for 24 hours before shipping, but on the STD because of being battery operated I don't. You can add long cables after the base unit if you like and it will work fine. The purple cable should be plugged in as close to the guitar output as possible, either into the guitar jack or your last pedal. The STD basically eliminates the cable capacitance because it converts the guitar to lo z (lo z is far less susceptible to capacitance) and if it's plugged into the guitar it's like you aren't using a cable. If you like the roll off of the cable you use, use a barrel connector plug your cable into your guitar then the other end into the barrel connnector (female/female) than the STD cable that will give you the roll off you might have liked when plugging straight into the amp without the std. Hope that helps.
