    Hey everyone my great aunt just gave me a Yamaha fifty-112 that she had in her attic for many years. There doesn't seem to be much info on the web about these amps. I believe mine is the first generation that was produced. Does anyone know how old that would make it? Also, I've heard it's a solid state amp, but mine looks like its got tubes in it. If anyone has some info that would be great!

    The first amp I ever bought, at age 16 in 1981, was a used G30-112. It was four or five years old at the time, and had belonged to a jazz session musician. I've still got it, and it's a great amp for warm, jazzy clean tones. It's solid-state. Its built-in distortion is lousy (and so is its reverb), but it does a passable job with an overdrive. It's got a MASSIVE Yamaha Black Max (I think that's what it's called) speaker, which makes the thing much heavier than it looks. I would imagine that yours is just a more powerful version of the same amp, but I'm no expert on that line. I'm pretty sure they made them in versions up through a 100-watt 4x10. Would love to see a picture of it.

    They are popular amps with Jazzers and others who like big clean sounds, they are cool with a compressor and a OD pedal running infront, and if you like lo fi distortion, I have had good luck kicking in a EQ when using the built in circuit..set to taste...:lol:
    They are well made and very reliable.

    The very first Yamaha amps were triangular when viewed from the side, they were replaced by grey amps with blue grille cloth..the black ones with the silverish cloth were next IIRC.

    Yamaha G50 112 , 50 watts , one 12" speaker, reverb .

    I had one a while back, very warm sounding for a ss amp, the reverb sounded good too, the built in distortion no so great but put a good pedal in front of it and rock on.

    I had a later model with a really cool parametric EQ for the mids, that made the amp very versatile.

    Mike Stern used to use these a lot as did a lot of other guys, they are good sounding amps, the G50 is lightweight too.

    Yamah made a Series II and Series III of these amps, the later ones have more sophisticated EQ and seperate clean and OD channels.

    Here is one on eBay for reference

    SS all the way, the cylindrical things that look like tubes are probably capacitors....

    Ok thanks for all the info everyone! I've got to do a little electrical work to get it sounding normal again.

    The first-model Yamaha G50-112 came out in the mid-70s. My best buddy and I each had one and they served us both pretty well as gigging amps. Nice clean sound with reasonable headroom, perhaps a little light in the bottom end, and the distorted sound may not have been great but it was usable. I went on to get a G15-100 too. Nice enough amps in their day and if yours is in decent condition, once it's fixed it should serve you well for as long as you want it to.

    Back in the 80's I used a borrowed G100-212 to run my acoustic through. Sounded much better than the PA. Those Yammies are nice are just starting to see a resurgence of interest.

    I had that exact amp for years. Very nice, warm clean tone. Distortion (as expected) not so nice. I'm not a distortion guy, so no worries there.

    My only complaint was that I thought a 50-watt amp should have been louder.

    Good, clean and reliable amps.

    My sentiments exactly. Wish I still had mine, but I was getting buried volume-wise in the band I was in so I had to move it. Nice amp.

    Hello, I have the same amp. It just started fading in and out after 10 minutes of use. What did you have to do to your amp electrically?

    My buddy has one. I was at his house for the first time in years and he had it sitting back in the corner. I think it was his first amp from the 80's as well. He got it used for $50!

    I had the G50-112, plus the G50-210, and the 100 watt, 1x15 bass amp. Great amps!

    I had one back in the early 80's too, a step up from the Guild Model 1 amp I had-still not a great amp (though the clean tone was alright), wound up trading it STRAIGHT UP for a '49 Fender Deluxe (wish I had THAT amp, fer sure!!!)... at a music store no less...

    Jimmy Thackery used to use the 4-10 model with the Nighthawks back in the day... they were indeed very reliable amps!
