Before you plug in:
Take a quick look inside the back of your amp. Make sure of the following—
1. The tubes are securely seated in their sockets (see page 15 for further information on checking for loose
tubes).
2. The internal speaker’s cord is plugged into the Speaker 1 output (this jack must always be used first).
3. The power cord is plugged in.
4. The FS-7 footswitch is plugged in (this is optional).
Now look at the front to make sure:
1. The Volume and Master controls are set at low levels (2 is a good starting point).
2. The Power switch is off (the lower half is pushed in).
3. The Standby switch is set to standby mode (the lower half is pushed in).
Plug in!
Now plug the amp into the wall, plug your guitar into either input jack, and set your controls to one of the
Quick Start settings outlined here. Then turn on the Power switch. Wait for about a minute for the tubes to
warm up. Turn on the Standby switch. Now it’s time to rock.
After you’ve played with your Hundred Duo Twelve for a while, check out the rest of the manual for some
good tips on getting the most out of your amp.

If you’re looking for a good starting point, try these settings. Remember that every guitar sounds different, so
try both inputs, and adjust the reverb and presence to suit your taste.
