V30 (30 W) greenback is a good choice for a MA50C
but for a MA100C I dont believe thay will resist
the 100W output !

Jagermike & Lizzy I totaly agree about the MA sound when played load. It's sound better that's all. I personaly think that, even if the MA is consider a low budget tube amp, it is not made for a non skill player. What I mean is, It need to be ajusted perfectly to give it's best. You will not reach a...

Well new curtains wont work she changed everything last summer, after she put me in contribution with some major renos in the house lolll But their is some hope, she want me take make a new bathroom upstair this summer lolll. So, I give it a try with my VOX ICE 9 & my GT10 it took me 15 min to plug ...

Nebulozny Thank's for the advices. The sad thing is that I used to own a SD-1 many years ago but I guess the VOX ICE 9 should work pretty good also. And since that I bought it recently, if I decide to change it, I will have to pass through the administration concil lolll (women doesn't only complain...

I personnaly think that Electroharmonix sucks sorry if I offendent some peoples.
I use JJ.s Tesla in all my amps.
I made some shows using my MA but still it seems that it didn't brought the amp up lollll
I have one gig comming on April 26 maybe after that show the MA will be famous lollll.

Nebulozny loooollll The same kind of stories apply here, it's so funny ! I'm sure those girls use telepathic. Ok so you are boosting the front (input) with another OD pedal to get more gain + the OD channel vol around 8 or 9 to give an extra punch and the SD-1 is use as a master vol... Cool setup. I...

lolll Nebulozny
I love your "wife tolerated volume levels" it seems like what ever country you're from, woman are the same lolll.
Now about your setup...Do you leave the SD-1 always "ON" ?

Hi I personaly dont use the "Clean Boost" method in the effect loop. But I use this set up directly in the input of my MA100C. I tried it in the effect loop and it didn't sound pretty good. Maybe I didn't plug it right but passing thru the effect loop made my amp sound loader but with not the amount...

Hey Steve, thank for the inputs. I've today today on the net and found some J174.
So i will perform the operation myself. Never better serve but by yourself .... I'll give you guys the result of the operation later : )

maybe component tolerances could cause that but it would have been flagged during final sonic and functional testing. From my personnal experience in Quality Assurance (20 years for a big Aerospace cie) I know that Inspection and FTP are not always done as per Eng. requirements. Since I still have ...

Yep guys I agree with you the V30 greenback would probably make a much more dramatic change in the tone but will it sustain the 100 watt of the MA100C. The aim of this post was just to bring some clarifications to some comments or concerns that I read here and there about the Eminence speakers and a...

Hello After reading some posts about upgrading the AX-75 Eminence speakers installed in the MA series, I was curious to see if in deed changing the original speakers would do a major change in the tonal response of my MA100C. I must note that, I’m actually pretty happy of my purchase. Except that I ...

Hi jagermike66

By having this arrangement, it's saturate the input with a Hi-gain signal causing distorsion. Using this set up in the overdrive channel combine the overdrive of your amp + the saturate gain of the pedal.
In the case of the MA series amp, it work pretty good !

Hello DK2
Yep ! Same thing for me. On the overdrive channel only. It's the way this amp is design.
Lolll I told you on another post you need top crank this volume to enjoy loll not to put it down.

Enjoy ciao !

Hello DK2 I have a MA100C and I love it more and more day after day ! I had also had bias ajustment issue and I bough this amp brand new. The Bias was over tolerance past 80mA insted of 76mA. Re-adjusting the bias did improved the sound greatly. I guess this is due to transport and climatic changes....
