Become a master of metal with this versatile, brutal head.

The Engl MetalMaster 20 head offers 20W of tube-flavored brutality built specifically for the heavy riffing and shredding solos that the metal gods demand. Featuring two channels (clean and lead), a switchable FX loop, built-in reverb, a mid-scoop switch for extra brutality, this little beast delivers the goods without overloading you with knobs and switches — or backache. Plus, with power attenuation from 20W to 5W to 1W or speaker mute for silent recording, this potent, portable combo is just as capable on the stage, the studio or in bedroom practice. 

Whether you're into a '70s hard rock, '80s shred, modern-day drop tuning or anything in between, the MetalMaster handles it with ease.

    Comments about Engl MetalMaster 20W Tube Guitar Amp Head with Reverb:

    This amp has the typical ENGL high gain awesomeness but with surprising versatility. The cleans are fantastic and the reverb is really sweet. But who are we kidding, anyone looking into this is after killer ENGL distortion and this amp delivers. Super tight low end, aggressive mids, crisp high and with lots of attack but never harsh, tons of usable gain, low noise. This amp along with the Ironball 20 is about as good as it gets for a low wattage tube high gain head. Love it!

    Comments about Engl MetalMaster 20W Tube Guitar Amp Head with Reverb:

    First off this is a hybrid amp, having just 2 preamp tubes most of its gain is obtained through circuitry. It has tons of gain on tap it just isn't warm like pure tube gain, bear in mind I'm a Mark V user and maybe given my preference it's just not for me, I play mostly 80's to current metal and although this can get your there it lacks the clarity and note definition other amps can provide. If you want a simple metal machine and this fits in your budget it seems well built, offers reverb and a decent clean channel. However if you want something more on the musical side of things this isn't your amp. Also lacking a footswitch at this price is a negative in my book, plus it requires 2 or a 4 button switch with 2 cables.
