Feature:
Here no problems.. there are quite a few bits to play around with to tweak your sound. Quite nice to have the options available. Sadly when the "25w" VPR switch is engaged the cruch channel suddenly lack of every thing and the lead and clean channel sound more like a valvestate.. I would have gladly traded that VPR thing against a proper factory biasing. would have saved me a lot of time. The mute button though is much appreciated especially when doing some late night recording.. Genius Idea. Took a long time to turn up though.

Quality:
Built to last.. that's marshall. The back grill looks like it could take on a collision with a truck. No complaints there.

Value:
Well for the money it's not a bad deal. Could be better if it was setup properly in the first place and included better tubes.

Desirability:
Looks very hot. Classic Marshall. Black Gold and white. I love it, but then again that kind of a personnal thing.

Sound:
Well, the good old Marshall Sound.. Though in order to get there you have to discharge the plate voltage and re-bias the power tubes. Maybe put some new quality ones (Tesla, Groove?) while you're at it.. Stock tubes could be better to stay polite. Once this is done the clean channel is what you would expect from a marshall head: godly. The crunch channel isn't too bad but could see a lot of improvement if used with 1960AV/1960BV (with vintage 30 celestions) cabs. With G12T-75s it feels as if something is missing in the sound. I would recommend trying different cabs before buying. Though the Lead channel has much more headroom. You can get a really nice natural tube compression when the gain is set high. Great for tight shred. :)

Support:
Don't really know since i've never dealt with them for support.

Overall:
I wish i could give it a ten but i can't. These tiny mistakes that could easly be sorted out by marshall if they could be asked let the name and the product down. For the people putting down this amp (most of you mesa lovers) i suggest that you try one wich has been setup with new tubes and attached to an AV/BV cab. And for the Mesa people: This amp isn't designed with a cascade gain preamp so there is no point comparing it to a Mesa amp becuse it's a totally different thing. I totally agree that when it come to enormous gain, Mesa's sound extremely good even though they are stupidly expensive.

Feature:
The only issue I have with this amp is the footswitch. But let me say here IF ANYONE SAYS THAT THE FOOTSWITCH BREAKS IN A MONTHS TIME, THEN THEY ARE ABUSING THE PRODUCT! I gig regularly, and I got this amp when it came out, in 1999, and I have only had one footswitch fail. It took a year and a half before it did too, and I called Marshall and I got a FREE REPLACEMENT!!! And this one has never failed. I bought a 2nd TSL 100 in 2004 and since then the footswitch has been upgraded to a more heavy duty cable, and I have had no problems with it.

Quality:
The only thing I would want to change about this amp is to update the controls in the back. The JVM has a great feature, the wet/dry control for the FX loop, which I wish I had on my TSL for my dial FX loops, plus a true bypass on it that you see on the new JCM 800 reissues. Also Marshall's idea on the JVM and Vintage Modern, to use a regular guitar chord as your footswitch cable is AWESOME!!! Come on Marshall!!! DO THIS FOR ALL YOUR AMPS!!!!

Value:
The BEST, bar none

Sound:
This Amp is my favorite. I'ved used other marshalls (The new JVM, vintage modern, and older 6100, and 4100) and Mesa Boogies (The road King, and Triple Recitfer) And this amp is the best in my opinion. Just make sure you got new tubes (if one tube is bad, they will all sound bad, that goes for any amp) a good cabinet, and a good guitar.

Ease of Use:
This amp is very easy to use, and great to customize your sound. The Bass boost, mid shift and tone shift buttons are a godsend. ANd this is the ONLY MARSHALL WITH DIAL PRESENCE KNOBS!!! great for adjusting your sound prefectly. Also The VPR is great at home and recording.

Support:
Marshall has always been easy to deal with for customer surport.

Feature:
I couldn't buy another amp that was more universal than this one right here.. You have so much flexability with the 3 independent channels / EQ's.

Quality:
Hey it is made by Marshall. Need I say more?

Value:
Amps like this are like wine, they only get better with age.

Desirability:
When you have a Marshall full stack with the JCM2000 TSL100 on top of your two cabinets, there is nothing sexier.

Sound:
This amp will knock you on your ass, pick you right back up and throw you off the stage. I wouldn't buy any other amp than this one right here. The power if awesome and the tone is god like.

Support:
I've never had a technical problem with these amps. But the times I had questions I received an answer straight from the company in no time at all..

Overall:
I will stick with Marshall forever. Me personnally I believe that I get a better tone and quality of sound for the amount of money I spend on Marshall than anyone else (i.e. Mesa Boogie).

Feature:
The cool thing about this amp is the features. Although don't use the vpr switch. The dual effects loop is an extremely cool added feature!

Quality:
It's a marshall. Of course the quality is going to be good.

Value:
Great value for the money you spend. Alot less than a Boogie.

Desirability:
Looks like a Marshall

Sound:
It's pretty funny when I play on the weekends the sound guys always compliment my rig because it's so easy to get good tone. mesa is only good for saturated overdrive for new metal, as for any other tone there a piece of crap. Way to expensive also!!

Support:
I have not had to use support yet.

Overall:
Overall this is the only amp you will need for playing rock n roll. Any kind of rock n roll.

Feature:
all three channels are money. the two effects loops are a plus. plenty of reverb if you want it. banlanced XLR emulated out just in case. the footswitch is well made and easy to use

Quality:
built solid

Value:
you pay alot for this amp but it's quality. it was worth it for me

Sound:
pure money. the clean channel is great. both distortion channels really crunch. it takes a little practice to get the sound you want. some people were complaining about the distortion not being thick enough. if you crank the gain and mid eq up and push that deep switch it gets as thick as any other amp i've heard. sounds best at loud volume settings

Support:
no experience

I dont know if any of you have ever even played one of these before. It's a great rock amp, and it can also be a great metal amp. And the fool who sed that mesa's can switch to solid state preamp/poweramp in case they blow tubes... you obiously dont own one because the switch for silicon diodes or vaccume tubes is for the rectifier (getting the voltage and current into useable levels to briefly explain it). Rectifiers ALWAYS use tubes in the preamp and the poweramp sections. Anyways, my two favorite amps in the world are the Mesa Triple Rectifier and the Marshall JCM 2000 TSL 100. I have both and I would never trade in for another rig, no, not even for a rack system. I run both of em at the same time for the most killer tone you have ever heard, omg... You'll see me in the papers/news/mtv soon ;) Overall, very killer amp!
