The Mini Z is back in acon with a few tweaks. Now available as a head and a 1x10
combo…this is the same circuit and tone many have grown to love from the original Mini Z
1x8 combo. We have added a built in aenuator! You can turn it up to get maximum output
tube distoron and dial it back to apartment dweller approved levels…tons of singing sustain
that you can talk over. The Mini Z will also shine on smaller gigs where volume is a concern.
The Mini has dedicated 8 and 4 ohm outs for different speaker cab applicaons. Put on top of
your favorite cab and go for it. A single EL84, a single 12AX7, 5 was down to under 1
wa…it’s very easy to like the Mini Z.
Clean headroom? Well, this amp wasn't built to give you much of that, but cleaner tones can
be achieved by rolling back the guitar volume. But, if you're like the rest of us, that'll last
about 30 seconds and then you'll have the guitar on 10 and be wailing away again...
The breakup begins lightly at around 9 o'clock on the dial, and the sound gets faer and
faer with more gain as you turn up the volume. Want a nice & crunchy rhythm tone? It's at
about 10-11 o'clock. Want a nice, sustaining tone for leads? It's at high-noon. Want ZZ-top?
It's at about 2-3 o'clock. Want over the top saturaon? Crank it all the way up. The amp gets
both louder AND more distorted as you turn it up, so it's "quite a ride." Most will find a happy
seng between 12 and 2 o'clock and control the volume and tone with their guitar.
General Informaon
Specificaons

1. Input: Input jack for your guitar.
2. Volume: Controls overall amp volume. As you turn the volume up more natural drive will occur along with
an increase in level.
3. Aenuator: Aenuates signal between amp and speaker. You can dial in your tone with the volume knob
and dial back the overall volume by turning aenuator clockwise.
4. Power: Switch up to turn on amplifier. Switch down to turn off amplifier.
5. Power Indicator: Lights up when power is switched on. If bulb fails replace with type T47.

6. AC Inlet: (Class I Wiring). This device is used for disconnecon from power mains and must remain
readily opearable. The power indicator light does not indicate connecon to power mains. The power
cord must be disconnected to disconnect amplifier from power mains.
7. Fuse: The fuse protects the amp from electrical faults. Replace only with the same rang and type
stated below fuse holder. If the amp repeatedly blows the fuse contact your dealer or Dr Z Amps.
8. 8/4 OHM Speaker Impedance Switch: Switches impedance of the speaker output jack signal
between 8 OHM and 4 OHM. Use this to match the impedance of your speaker cab.
9. Speaker Jack: Plug in speaker here. Always have a speaker plugged into the amp when it is powered
on. Always match the speaker impedance to the proper speaker out jack. This will allow the amp to
sound its best and avoid damage.
