Re: Marshall JCM 2000 TSL602
I have had many Marshall's, as well as other amps over the years. I have a TSL 60 head. Here is the deal with these amps. They have a bad rap which is not really deserved for the most part tone wise. Here is the skinny...
The clean channel is decent.
This amps needs to get loud or it's fizzy on the OD channels.
The red or lead channel has stupid amounts of useless gain that really is not practicle. The gain over 4 or 5 sounds like a bees nest.
The reverb is so so at best.
The footswitch is a $150 nightmare of bad design just waiting to break on you. If you gig this amp, you WILL break this footswitch. I babied mine and it still broke.
This amp needs to be tweaked EQ wise. The knobs make a big difference with slight turns. If you put everything on 10 it will sound like mud.
This amp really benefits from old glass or at the very least decent CP tubes.
These are a tech's nightmare. They are very difficult to fix when they break. Mine has been in the shop now for 2 months. Lots of techs won't touch them.
Ok that's the bad...now here is what is important.
The crunch channel, with the gain up about halfway and the master cranked is the essence of bone crushing kick ass vintage Marshall tone. It is very cranked 800ish and sounds totally killer. I use a DR Z Airbrake so I can crank this Thing or else it sounds like a different amp. I have put it next to quite a few Marshall's other guys were using and it blew their minds, as most had either never given this amp a chance or read a lot of Internet rehash from people who can't get tone from these things.
Bottom line, it really only has one great tone. If you want a super versatile 3 channel amp, it will do the job but you may be dissatisfied. If you want a great sounding classic Marshall tone that's FAT...this will work for you but it must be loud.
