1. Input:
Input jack for your guitar.
2. Sensitivity:
Controls the level of signal at the input. This allows you to adjust for the ouput of your pickups. Setting
this control higher will fatten up and boost single coils, lowering will clean up hotter humbuckers for a clearer sound.
3. Gain:
Controls the amount of preamp distortion.
4. Treble:
Controls the overall high frequency response.
5. Mid:
Controls the overall midrange frequency response.
6. Bass:
Controls the overall low frequency response.
7. Aggression:
Controls the amount of power stage distortion. Turn this up for a tighter, brighter, and more aggressive
distortion loaded with upper frequency harmonics great for fast rhythm playing. Lower this control for a more open
and broad response for smooth lead playing and massive sounding open chords. This control will increase the
perceived volume level when the Level control is past 12:00.
8. Presence:
Controls the overall high midrange response. The control’s effect will be diminished the higher the
Aggression is set, as this control interacts with the same frequency spectrum as the Aggression effects.
9. Level:
Controls the overall volume (loudness) of the amp.
10. Stand-By:
Leave in off position for 1 minute when powering up the amp. Turn on for play. Place in off position for
extended break periods.
11. Power:
Switch up to turn on amplifier. Switch down to turn off amplifier.
12. Power Indicator:
Lights up when power is switched on. If LED fails replace with a 6.3 volt #44 Bayonet Base(BA9S).

13. Send Jack:
This will send the signal from the amp to the “in” of your effects chain.
14. Return Jack:
Plug the “out” of your effects chain to return the signal back to the amp.
15. 16 Ohm Speaker Jack:
Plug in an external 16 Ohm speaker here. Use only one output at a time. Always have
a load connected to your amp.
16. 8 Ohm Speaker Jack:
Plug in an external 8 Ohm speaker here. Use only one output at a time. Always have a
load connected to your amp.
17. 4 Ohm Speaker Jack:
Plug in an external 4 Ohm speaker here. Use only one output at a time. Always have a
load connected to your amp.
18. Fuse:
The fuse protects the amp from electrical faults. Replace only with the same rating and type stated
below fuse holder (2A 250v SLO BLO). If the amp repeatedly blows the fuse contact your dealer or Dr. Z Amps.
19. AC Inlet:
(Class I Wiring). This device is used for disconnection from power mains and must remain readily
opearable. The power indicator light does not indicate connection to power mains. The power cord must be
disconnected to disconnect amplifier from power mains.
