So there's been a deal at GC. G-DEC 30 amp for 99 bucks, down from the normal 299 dollars. I can trade in my MG100HDFX and get a G-DEC with still enough $ left for a Crybaby or Vox wah pedal from the trade.

Question:

is it good at modeling amps? How effective is it if you use the inbuilt 10 inch speaker? What if you hook it up to a quality 4x12 cab? Then, will it sound 99% like one of those multi-thousand dollar amps that it allegedly models?

Volume isn't an issue.


How about its sound compared to that of a MG100HDFX?

Depends on the speaker(s) in the cab, but no. A solid-state modeling amp will hardly ever sound exactly like the real deal, especially on a beginner amp. A 4x12, 2x12, even a 1x12 will sound better/fuller than a 1x10.

It seems like a solid amp from what I've read. Almost anything will beat an MG, so... listen to some video or audio clips and decide for yourself.

TS, fill out the information here and we can help you more:

From what I understand, the GDEC is not that great, but neither is your MG. Fill out that information, and we can help you out much more. With the money you can get from selling your MG, you could buy a MUCH better amp. In fact, from what I've got out of your first post, I think a Peavey Vypyr Tube 60 with a Sanpera II footpedal would be an excellent choice for you, and that can be had used for around $400.

Fill out that information, then we can actually help

You should decide what you want first. These amps are clearly different in application. The GDEC 3/30 is a great amp for practice and jamming along with backing tracks/rhythms. Also if you spend $50 on the footswitch it has a built in looper. Whereas the MG half stack is good for taking up space and sounding nasty real loud.

The GDEC cannot be plugged into a cab unless you take it apart and rewire the speaker connection. I have the GDEC 3/30. It sounds pretty good, but isn't going to rival any expensive amp it models. The Fender Fuse software makes creating presets very easy. I don't like things about how they implemented the looper and F/S functions. But overall I think that the amp is a great deal and solid piece of gear.
