Jvm 210c

I'm looking for a portable amp for gigging in small to medium size clubs. Tired of carting my full rig to bars, its starting to wear on me. I've done some research on it but the youtube videos are for crap. I'll probably go to GC or the like and try it out. Just wondering if anybody has any experiences with it and what I can expect in trying to get the legendary Marshall sound. Pros and Cons. Thanks.

Re: Jvm 210c

The JVM is an ultra-modern take on the Marshall tone. It's powered by the incredible EL34 power valve and has 4 ECC083 pre-amp tubes and a power-inverter. Digital reverb is nice, but the OD channel can get a bit noisy. It has an effects loop and a Power-amp Insert section so you can feed the amp to/through a separate power amp. The FX loop can be a bit tricky to get used to at first.

The speakers, you get 2x12" Celestion speakers: a Vintage 30 and a Heritage. Puts out 100-watts RMS power. Yadda yadda.

How does it sound? Like a boosted DSL, a JCM800, or a clean 1959. The Clean/Crunch channel goes from plexi cleans (possibly cleaner) to boosted JCM800 and everything in-between. The Overdrive channel has enough gain to step up next to a Peavey 6505+. Why you would want that much gain, I don't know. But it's there.

Lots of people like to mod their OD channel to match OD1 on the JVM410. The mod is changing two resistors. It centers the MIDDLE tone pot at 650Hz instead of at 500Hz, giving you a slightly more classic Marshall tone. Some others do the Plexi cap mod and then yet more do the negative feedback mod.

The JVM series employs lots of negative feedback in the power-amp section to keep the bass and drive tightly controlled during heavy amplification. This is in the same vein as the JCM800, JCM900, DSL/TSL, etc. By contrast, the JTM45, 1959/1987 Plexis, and the like all had relatively LOW negative feedback, allowing the power amp to really explode with sound and is mostly reponsible for that vintage Marshall overdrive CRUNCH sound. The -feedback mod puts a pot on the amp allowing you to dial in however much of it you want. Combined with the Plexi cap mod, you basically turn one channel of your amp into a high-gain plexi.

But that's all way in the future, even IF you decide to do stuff like that. JVM tone? This video made my decision for me and I bought a JVM410H. Your mileage may vary.

Re: Jvm 210c

I've got the 205c which is the 50w version. I've got no complaints; however it is quite a heavy beast. The side handles make it a fair bit easier to lug around than my 4210 combo which only has one 12" speaker though.
