Amplifier Discussion / Yamaha G-100 Head
« on: January 25, 2020, 01:49:32 PM »
 Hello Forum,
  I've had my Yamaha G100 now for about 4 years. I really love this amp. There is a jack on the back of the head labeled "Record output". Because I have no way of recording with a mic i would like to try using this and I have with no success.
  I believe I'm using or doing something wrong. The schematic says "+4dBm nominal  +31.2dBm max  For 600 ohm unbalanced lines". 

 So far Ive tried using a guitar cord from the record out to my instrument in jack on my Line6 and got nothing. I didnt want to risk frying anything so thats all Can anyone explain what im doing wrong and how I can properly use this jack. Everything on the amp works perfectly (I bought it used) so I dont think anything is wrong with the amp.

ANY help on this would be greatly appreciated Thank You

I know it's an old post but fer the helluv it my 2 cents. Ive had my G100 for 6-8 months $120out the door at a pawn shop. At 1st I couldnt get any good tones then I started stacking different pedals in front and........HOLY Sh**. Im using an Ibanez s series with Boss MT into the clean head.  FN" insane when you spend some time with the pedals dialing in small nuances really pay off.

Oh yeah and a buddy of ine calls me saying he found some speaker in an alley (actually 2 of em) and do I think I'd want it . Lansing something or other h says. Bring it over I said. $40 later I had a vintage 15" Lansing woofer. Built a quick box painted black And window screen over the front painted black. Really...outstanding. Thru fluke things that happen I have a killer setup.

Although I still feel the yamaha distortion really weak and foul sounding and despite what I've been told I do believe the head can be modded to fix that. I just don't have the exact knowledge of how to do this but in time.........in time.

Amplifier Discussion / Yamaha G100 Head distortion and foot switch
« on: April 14, 2017, 04:05:29 AM »
Hello,
 As I am fairly new to DIY and electronics I have uploaded the schematic to my Yamaha G100. I'm hoping someone can help me out by telling where the distortion section is and what type of distortion is used and is it mod do able. I find the distortion fully cranked very weak and going clean with different combos of a DS-1, ross comp., a cheap overdrive and a cheap blues breaker style. So far Im diggin the DS-1 into a Nuxx OD-3 (now when I go through my little fender Bullet using the Bullets distortion and these 2 pedals it screams (and I LIKE a LOTTTT) but much weaker and blatty using the Yamaha. I figured they are both solid state could I get the fender distortion sound from the yamaha?

  Also I've been scouring the internet trying to find out the wiring for the footswitches. Can any body help e out here? Maybe draw up a schematic of how I am to wire one up. Like mono or stereo plugs? Latching or non latching switches?  momentary or non switches? I have the skill to do fairly good modding and building just lacking the ability to really understand and comprehend the whys and hows of electronics. Building kits and diy ing is 1 thing but total comprehension of a schematic is a totally higher level IMHO

Scoticus,
  I recently picked up a Yamaha G100 head awesome price and even better sound!
 I was wondering if you know or anybody on this forum would know how to go about making my own foot switches for this amp. Also have you found any literature on your amp if so where? Like an owners manual I believe mine is series 1 but I don't know for sure  how to tell.
  I was able to wire up one of my speakers from another little practice amp to tr out the head everything works I just don't have the foot switches or any info on the amp.
 Any info or help would be really appreciated.

thanks in advance

Hello Forum,
   I am hoping some one out there can give any info on this particular model. I dont have a cabinet but I do have 3 little SS amps 1 crate and 2 fender bullet amps . I was hoping that 1 or 2 of those speakers could work providing they match ohm ratings. Am I correct? And 2nd where and what kind of speaker cable do I get? On the back of the amp head there re 2 outputs. 1 says 1 ou 2 : 4~8 ohms  and the other   says 1 + 2 : 8~16 ohms.  I am assuming this means 1 of the outs is for 4 to 8 ohm speakers and the other for 8 to 16 ohm. Am I correct?
   Any insight would be greatly appreciated Thank you in advanceXFHATK
