PLEASE NOTE:
-THE WIRE LOCATIONS ON THE DIAGRAMS ARE NOT IN THE SAME ORDER AS THEY ARE ON THE
MODULE AND WERE ONLY DRAWN THAT WAY FOR SIMPLICITY. FOLLOW COLORS, NOT WIRE ORDER.
- IF NOT USED, THE BOOST LEAD SHOULD BE COVERED WITH ELECTRICAL TAPE OR SHRINK
TUBING TO PREVENT GROUNDING. VERY HIGH GAIN, NOISE, AND DISTORTION WILL RESULT IF THE
BOOST LEAD IS GROUNDED.
-DO NOT OVERHEAT PINS OR WIRES. USE A LOW WATTAGE (25 WATTS MAXIMUM) OR A
THERMOSTATICALLY CONTROLLED SOLDERING IRON AND GOOD QUALITY ELECTRONIC SOLDER.
APPLY THE LEAST AMOUNT OF HEAT FOR THE SHORTEST TIME NECESSARY TO MAKE A GOOD
CONNECTION.
-AS ALWAYS, WE RECOMMEND TO TAKE YOUR INSTRUMENT TO A GOOD GUITAR REPAIR SHOP.

The TC2, TC4, and TC6 preamps are the “stereo” 2-channel versions of TC1, TC3, and TC5. The output impedance of
the TC preamps is 60K-ohm. The unboosted gain is measured with a 500K-ohm load. If these preamps are used with
250K-ohm volume controls at the output lead the unboosted gain will be slightly lower (~1dB). If 25K-ohm controls are
used at the output lead the unboosted gain will be lowered by 6dB (half the output) without distortion.
The maximum undistorted signal level of all the TC preamps is 2.5 volts r.m.s. The maximum input level for undistorted
pickups output (unboosted) is 2.5 volts r.m.s. divided by the unboosted gain. This means 250 to 300 millivolts for the TC1
and TC2 preamps. The TC1 and TC2 should be used only with pickups that have very low output levels, otherwise the
pickups will overdrive the input stage of the preamp.
