TUBES
Preamp tubes last longer than power amp tubes and the need to change them occurs only
after thousands of hours of playing. It is still best to turn the POWER switch off when not
playing through the MP‐1‐CHANNEL. This will lengthen the life of the tubes. When replacing
the 12AX7 vacuum tubes, always use high‐gain, low‐noise selected tubes for best performance
and the lowest noise.
At high gain settings the inherent mechanical (microphonic) noise can become an issue, so be
careful not to tap, kick or bump the MP‐1‐CHANNEL while playing at high gains. The
mechanical noise will show up in your sound.
QUICK HOOK‐UP
When using a combo amp or a head and guitar cabinet.
1. Set the POWER switch on the MP‐1‐CHANNEL to its OFF position.
2. Plug in the supplied AC adapter (12VDC at 800mA, 2.1mm plug, center negative) to
the MP‐1‐CHANNEL.
3. Turn on the source power to the AC adapter.
4. Set all the controls to 12:30 o'clock except OD1, which is set at full counter
clockwise.

6. Set the TRUE BYPASS foot switch to bypass, LED off.
7. Connect your guitar via a high quality cable to the INPUT of the MP‐1‐CHANNEL
