Hey guys, I am looking at buying this peadal, I've played one and they're awesome! what I want to know, and (I'm guessing) Aschleman can help me here, is the difference between the standard Fulldrive and the 20th anniversary Mosfet Fulltone Fulldrive? I know I should probably know this, but I dont, so can anyone help me out?

The MOSFET is just going to offer you a slightly different tone... What Fulltone is probably doing is using a different chip (MOSFET chip) instead fo the standard chip that they use in the standard Fulldrive...

The style of MOSFET chips used in this Fulltone Fulldrive are more commonly found in tube amps of the 80's and late 70's. So I'm guessing it's just a vintage reissue pedal.

MOSFET stands for metal-oxide-semiconductor field-effect transistor... These transistors have largely been replaced by the CMOS versions which are an upgraded version of the MOSFET circuitry... Hard to explain it all in general terms without going into a long drawn out history lesson and electrical engineering 101 class....

In short, The MOSFET system was probably the circuitry that was first featured in the original Fulltone Fulldrive pedals back in the 90's... My guess is that this offers a bit more warmth but may also offer less tonal versatility... The newer Fulltone Fulldrive probably uses CMOS circuitry that utilizes multiple styles of smaller MOSFET circuits..... It will give you more tonal versatility but may not give you the solid vintage tone of the MOSFET exclusive version... It appears that the MOSFET version gives you the option of using the original MOSFET settings and the newer settings... So I would say go for the MOSFET version.... unless you're not that into vintage tones... Then just go with the cheaper Fulldrive without the MOSFET...

Hope that was helpful.

thanks Adam, I was counting on you there. I was just uncertain of how the Mosfet chip's sound would differ to the Cmos chip's, but since the Mosfet reissue contains both the Mosfet and Cmos circuits(does it?) this sounds the way to go, as it is only about 20$ more expensive...

as for the electrical engineering thing, as many, or none of you know, I am currently studying electrical engineering, and would like to shout out to the world, that afrter battling with math, I got my results back yesterday and I PASSED! Hooray!

Awesome man!! Congrats on that!

Basically from what I know about the cmos circuitry is just that it's new technology... Probably more diverse and gets a lot more versatility out of the tone... From what I saw on the Fulltone website was that the Reissue did in fact have an extra switch that allowed you to switch between mosfet and cmos... So yeah, that would defiitely be the way to gol. Sounds like a cool pedal!!

I don't know too much about electrical engineering since I'm just finishing up my mechanical engineering degree... But I've had to do some cross studying between all the disciplines of engineering so I know the basics... Cool stuff man... Congrats again on passing the EE classes.

yeah well, I have only completed one of four years, so at the moment I also know the very basics of EE...I have no doubt that your EE courses that you'd take to become a mechanical engineer will have currently left your ee knowledge much greater than mine.
But in this upcoming year we start to focus more on the electrical side rather than the physics and math side required for every engineering degree.

Thanks for your help tho man, I think I'll go with the re-issue

About every one of my classes throughought my college career so far have dealt almost directly with math... Except for a few design classes... But I've had to take Statics, Fluid Dynamics, Thermal Dynamics, and the ever dreaded Differential Equations........ which is by far the worst math class ever... along with the Calc 1-4 and applied Trig and Physics 1 and 2... and I don't even liike math... in fact I hate it... I'm not even good at it... My guidence counselor told me that I only have to take 2 more classes to get my minor in mathematics... how ironic is that??

Yeah man... in the future you'll be the go-to guy for getting info on electronics!!! haha. Glad I could help though! That reissue pedal looks pretty sweet... I almost want to snag one now.
