MR Z MZ-8: based on Dr. Z Maz 8

MR Z MZ-38: based on Dr. Z Maz 38 SR

Dr. Z is Mike Zaite. He builds simple amplifiers that sound pure and are appreciated widely. Famous Dr. Z amp players include Brad Paisley and Joe Walsh.

Cliff: "Dr. Z is the quintessential country amp."

These models are based on Dr. Z’s Maz amps. These are popular single-ended amps. These amps have no negative feedback (model: Damping is 0).

The Maz 38 Sr is an 38 watts amp (head or combo) with four EL84s. Controls: Volume, Treble, Middle, Bass, Cut (model: Hi Cut), Master Volume. The tone controls can be bypassed on the real amp. It has two inputs: Hi and Lo (3 dB less gain). The regular version has Reverb built-in, the NR version doesn’t.

Dr. Z:

“Big rockin’ amp with that undeniable Dr. Z sound!”​

“The Maz 38 is one of Dr Z’s most enduring designs. It is the perfect combination of sound and power. 4 EL84s with no negative feedback give you a wide pallet to work from. The 38 has enough clean headroom to make for a great pedal platform and gives up the goods for a great drive sound at reasonable levels. The 38 can satisfy many different styles and playing approaches. You are able to dial in mid 60s blackface sounds as well as UK flavored chime. The Dr. Z MAZ-38 is a truly versatile amp for the working or studio musician. Whether your forte’ is Blues, Country, Roots, or Rock, The MAZ 38 Senior will fit the bill.”​

The Maz 8 is an 8 watts amp (head or combo) with a single EL84. Controls: Volume, Treble, Middle, Bass, Reverb, Cut (model: Hi Cut), Master Volume and Pentode/Triode switch (not modeled). The tone controls can be bypassed on the real amp. It has two inputs: Hi and Lo (3 dB less gain).

Dr. Z:

“Based on the modern day classic Maz 18 platform, the Maz 8 is set to become the new standard in single ended class A amps. If you are tired of thinking of ways to win the volume wars with sound guys, club owners, and recording engineers the Maz 8 is the solution. The Maz 8 is a full featured 8 watt amp that will give you an incredible range of shimmering cleans to full on rock action at reasonable volume levels.​

The Maz 8 gives you the true class A experience. The single EL84 output section can be run in Pentode or Triode mode. In Pentode mode you get the sonic signature of the Maz 18. The chimey top end and sweet low end bloom are all there, but at a significantly lower volume. The pentode setting gives you plenty of dynamic range for clean country picking to grinding riff rock bliss. You can even take it a step beyond with the footswitchable EQ bypass function. This gives you a great gain boost for effortless leads that will sustain for days. The Maz 8 takes on a much different dialect in triode mode with more of a vintage feel and sound. In triode, the volume level drops back and the tone fattens up making you think you plugged into a lost gem from the 1950s. Kicking on the EQ bypass in triode mode will have you reaching for your slide in no time.​

Review of the Maz 8 in Premier Guitar.

Here are the manuals.

I really like these amp models, the Maz 8 even more than the 38. Not limited to country. They are capable of putting out vintage medium rock tones too. But they excel at clean tones at the verge of breakup. Loose and bold power amp sound. The ratio Input Drive / Master is important if you want to keep the sound tight.​

Pick a G12H IR to use with these models. I have KTS-70 speakers (by Austin Speaker Works) in my cabinets, which is a high powered version of the G12H, and these models sound awesome through it.

The Triod/Pentod switch is not modeled - so what sound do we get from our axemodel? The G12 Alnico speaker - is this the same as a Voxspeaker ? The videos sound really great with both amps, have to pick my Tele at once..........:D

Love me some Z. Especially the 38.
I don't use it for country... for me it's just a sweet lo-mid gain amp.

Pretty sure the switch is just power scaling and we have the pentode
