For sale is a Dr. Z Maz 18 MKii NR head, black tolex. Manufactured in July 2019, I've owned it since April 2026. It's a great piece of kit, but it's not my sound, so I'm moving it on. It's in great condition. While taking photos of this I snapped one of the tube retainer clips. It also has 2 scuffs on the rear bottom corner covers (shown in photos.) Includes the power cable and EQ Bypass/Boost switch. Willing to meet within 2 hours of Atlanta, or can ship. If you're interested in the cab as well I'm willing to make a deal, let's talk.

From Humbucker Music:

The Dr Z Maz 18 Jr MK II is easily one of the most desired amplifiers in the boutique amp world! Like all Dr. Z amps, it's all tube, all handwired and completely made right here in the USA!

First, if you are worried about the Maz 18 being only 18 watts, don't be. We're talking about 18 watts of all tube driven, class A, point to point hand-wired watts of Dr. Z tone! One of the features of the Maz 18 is it's ability to hang with a typical drummer when cranked yet because of it's lower wattage rating, it can still produce that full plate voltage tone in lower volume situations where it needs to be mic'ed. A perfect amp for studio or live use.

So how about the tone? Well, we like to place this amp as 80% modded Vox AC, and 20% Marshall Plexi. We love old Vox amps, but have often felt they are a little too "brilliant". The Maz addresses this by being a touch warmer at the top, but don't get us wrong. The top end is still there, but just not as much as the "ice picky" Vox amps of the 60's. The Maz still retains that wonderful mid range growl and punch you get from EL84s, so I wouldn't say there's a lot of tube compression going on. The Maz is a responsive amp, so you'll find you get back what you put into it. It's also important to note the Maz 18 plays very well with pedals. This isn't always so easy for an amp builder to accomplish on an old school hand-wired guitar amp, but Dr. Z must have it figured out since essentially all his amps are known for being very pedal friendly. For more tone info, feel free to call us. Like we mentioned earlier, we really know these amps!

The front panel features Volume, Treble, Middle, Bass, Master, and the ever versatile Cut control. Think of the Cut as a tone knob for the output tubes. That may or may not make much sense, but take our word for it. It's quite a powerful control!

The back panel features 4, 8 and 16 ohm speaker outs. An effects loop is standard, as is the EQ Tone Bypass (previously a popular factory mod).

This is the new and improved MkII version of the venerable Maz 18. The following is a list of improvements that have been made over the past couple years to become the Mark II version.

Specs:

• Voicing changes that warms the tone a bit, reducing some of the stark treble that comes with most EL84 based circuits.
• Newly designed post-phase inverter master volume allowing the player to fine-tune the tone at any volume.
• Buffered effects loop for for better integration with today's pedalboards.
• Power tube spec change from new production EL84's to NOS Russian mil-spec 6n14n (EL84) power tubes rated to last twice as long.
• Variable boost footswitch is included, providing anywhere from a small bump in volume to all-out, singing distortion.
