About the Marshall Haze MHZ15:

So what we have here is a 15 watt, two-channel amp jam-packed with features. It uses 3 x ECC83 and 2 x 6V6S to produce a huge tone without a huge footprint. A Normal channel and an Overdrive channel with a shared three-band EQ form the basis of the amp.

However, it also has 3 onboard effects; Echo, Vibe and Chorus. These effects are turned on via the front panel or you can use the foot switch. LED lights, each a different colour, tell you when an effect is on as well so you can tell at a glance.

It has the traditional Marshall design with the classic Marshall Overdrive channel to accompany it. A bright switch is shared between the channels and adds a bit more bite or sparkle. to your tone.

It’s worth mentioning also that the normal mode has a great amount of headroom for a smaller wattage amp, crisp and clean.
