Q: What kind of sound can I expect from the Electro-Harmonix MIG-50 tube head?

The MIG-50 delivers classic, powerful tube tone, reminiscent of vintage Russian amplifiers. Its 50-watt output, driven by Tung-Sol 5881 power tubes and 12AX7 preamp tubes, provides rich cleans, dynamic crunch, and singing lead tones. It's known for its robust low end and articulate mid-range, making it versatile for rock, blues, and other genres.

Q: How do the "Normal" and "Bright" inputs on the MIG-50 differ?

The MIG-50 features two distinct 1/4-inch inputs: "Normal" and "Bright." The Normal input offers a fuller, warmer tone with a strong low-mid presence, ideal for a classic, beefy sound. The Bright input provides more treble and sparkle, perfect for cutting through a mix or adding clarity to darker-sounding guitars.

Q: What speaker cabinets are compatible with the MIG-50 head?

The MIG-50 offers flexible speaker output options, allowing you to connect to various cabinets. It includes 1/4-inch outputs for 4-ohm, 8-ohm, and 16-ohm speaker loads. This versatility ensures you can pair it with most standard guitar cabinets, from single 1x12s to larger 4x12 setups, always matching the impedance for optimal performance and safety.

Need additional help?

Q: Does the Electro-Harmonix MIG-50 include an effects loop?

No, the Electro-Harmonix MIG-50 is designed as a straightforward, classic tube amplifier and does not feature an onboard effects loop. This means time-based effects like delay and reverb will typically be placed in front of the amplifier, allowing them to interact directly with the preamp's natural overdrive characteristics.

Need additional help?

Q: How do I adjust the bias on the MIG-50, and why is it important?

The MIG-50 features convenient external bias controls, making tube maintenance easier. Proper biasing ensures your power tubes operate efficiently, sound their best, and last longer. You'll need a multimeter to measure the bias current and a small screwdriver to adjust the external pots. If you're unsure, a Sweetwater Sales Engineer can guide you or recommend a qualified technician.

What an amazing quite versatile amp head this is. And they should have a picture of this beside the term LOUD. Hard to tame this thing. Takes pedals great!! Goes perfect with my Marshall 2x12.

It may say EHX, it may come from Soviet Tech/Sovtek heritage, it may even be all black and white in its vintage handsome looks, but it sure acts and sounds like a 50 watt Plexi head! The most wonderful 50 watt amp head, I have ever had.

From channel II, I am running it into a Two Notes reactive load, and Friedman Mic No Mo, and thru my audio interface and laptop, I crank this little bad boy to 9 and boost it up front with a trusty Boss Sd1, and Marshall bliss is attained. No crazy volumes and screaming cab necessary. I use a reverb and delay for effects thru my GarageBand, so I don't care about the head having no effects loop. Actually, the circuit is pretty simple and plexi'ish, so adding an aftermarket effects loop is totally feasible.

If you want a classic british plexi 50 watter, try this first.

I wanted a clean tube amp with a lot of headroom for a pedal platform, but didn't want to spend $2k. I owned a Fender Bassman for several years that was superb, but was stolen and way too expensive to replace. I know the old SovTec mig-50 was built with nearly identical architecture to the Bassman design, and when I heard the Electro-Harmonix mig-50 was a direct copy I figured it would be my best bet.
This Mig-50 has tons of power and headroom for a pedal platform, and sounds superb. Channel 2 is the brighter channel and works well with all types of pick-ups. On volume level 3 it easily reaches over 90 DB and didn't show any breakup past level 5 which is crazy loud through my 4x12 Marshall cab. I keep it on 3 for home use and use the volume on the guitar to adjust from there.
I mainly wanted a good tube amp for better overdrive and distortion in a wet-dry-wet set-up to go with a pair of Katana 100 MkII's. The Katana's work really well for everything except overdrive & distortion, so the Mig-50 ended up being the perfect choice.
The Mig-50 does not have any reverb or tremolo which isn't an issue when you have pedals. The ONLY thing the Mig-50 is missing that would really make it better would be an effects loop for delays and other time-based effects. Having such clean power and so much headroom it really isn't an issue in my rig.
It is a superb amp at a very fair price that willabsolutely blow you away with how much clean power and raw volume it can put out. Basically imho it is a SovTec or Bassman for under $.

I've been waiting for this amp almost as long as for Fender to put a gain knob on a Bassman 50. My Marshall Origin 50 head blew after 7 months, and "may I add" is underwhelming) and I needed something quick for a huge live show in my living room, so I was lucky this came in stock.
I ordered the "Mig" (perfect name) Sunday night online and it was here in Tx., Wed at noon. I let it sit for the 24 hrs to open it, and it was perfect! Simple, excellent instructions that even describe how to bias the tubes with the screw on the back. I set everything to noon (except the volume) on the front and it's a really nice sounding amp. It has a good range in the eq knobs and they actually do something. (Origin 50 reference) The volume knob is real edgy down low and this thing is LOUD. Who knew it would be a perfect pedal amp? I run it through an old 4x12 Marshall cab and it loves it. Plenty of bottom and a really sweet clean sound. The knobs/pots feel good and the switches are smooth, on the front panel, and don't make any "pop" through the speaker. A gain knob would be nice, but who needs it?
Nice, simple, valve amp. Let's hope it lasts...

This amp really melds well with the band I've been playing in for close to a year. Our other guitarist has a very defined sound with a Twin Reverb and needed something that gets along while standing out and this amp is it. It's very pedal friendly so I've been getting tight cleans and gain layers can make it sing. Just last night we got together to re-track and re-amp and dialed it in real nice and it was absolutely perfect. The only thing preventing a perfect 5 to me is lack of a master volume as it is loud loud but in my situation I can get away with the volume.
