A fantastic little 5w valve amp head with a built-in attenuator, to get the tone you want at the volume you want! In excellent condition with just a few light marks to the corners and casing (see pics). The 2 valves have been tested by ourselves and are good.

Here's what Dr. Z says about it:

The Mini Z is back in action with a few tweaks. Now available as a head…this is the same circuit and tone many have grown to love from the original Mini Z 1×8 combo. We have added a built in attenuator! You can turn it up to get maximum output tube distortion 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 applications. Put on top of your favorite cab and go for it. A single EL84, a single 12AX7, 5 watts down to under 1 watt…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 fatter and fatter 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 saturation? 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 setting between 12 and 2 o’clock and control the volume and tone with their guitar.
