The Electro-Harmonix MIG-50 is a 50-Watt tube amp head that is essentially a reissue of the original Sovtek amps, but with some modern-day updates to the design. Although out for a few years now, they were sold only in the US. It would appear that the company has now received all the international safety certifications required to ship these amps everywhere.

With a similar tone to the tweed Fender Bassman, this reissue of the Electro-Harmonix MIG-50 gives you 50 Watts of all-tube power to play with. It’s a pretty basic setup, which includes two channels: Normal and Bright, each with its own separate volume control, and a shared global EQ section that consists of Bass, Middle, Treble and Presence. You get the obligatory standby and power on switch. And, of course, a status light that lets you know it’s on and ready to rock!

Amp Specifications

The amp itself is powered by a pair of Tung-Sol 5881 power tubes, and one Mullard 12AX7 and two Tung-Sol 12AX7 tubes in the preamp section. This modern reissue also has a very handy external bias adjustment control on the rear of the amp head. It has the ability to power cabinets rated at 4, 8, or 16-ohm from three dedicated speaker outputs on the rear.

No master volume

As a modern-day reissue, this amp head should benefit from having the external power tube bias control and, I would imagine, sound juicy with the tubes that it ships with. It is still going to be pretty loud, as there is no master volume or any kind of power attenuation going on. So be prepared for some serious volume.

On the plus side, it could make a great platform for any pedals on the Normal channel, which should have plenty of headroom before breaking up. The Bright channel, on the other hand, should have more gain. And you can always push it further with your favourite overdrive pedal, should you so desire.


Asembled in the USA

Each MIG-50 amp is now assembled by hand in the Electro-Harmonix NYC factory in the USA, whereas the originals were made in Russia. Hopefully, the price will be enticing enough to tempt players to try one of these reissues.
