Tube 15

Fifteen watts of push-pull 6V6 through a 12-inch Celestion Seventy 80. Two Dane 12AX7 in the preamp, spring reverb, and one channel that goes from clean to cranked on the Master. The one that fits on a small stage.

1. InputPlug your guitar in here.
2. GainSets how hard the preamp is driven — clean when low, overdriven as you turn it up.
3. BassCuts or boosts the low frequencies.
4. MiddleCuts or boosts the midrange — the body of the sound.
5. TrebleCuts or boosts the high frequencies.
6. ReverbAdds spring-style reverb, from a hint of room to a long tail.
7. MasterSets the overall level after the preamp — turn it up for power-tube drive.
8. PowerSwitches the amplifier on — the pilot lamp glows when it is live.
