I use my Studio Monitors and my guitar tracks are incredible. Yes , I have the AxeFXII, but even when I had my Boss GT10 or even my GS-10 they always sounded good. I have to say the seakers have a lot to do with it. My MAckies are not the best by any means, but they sound great. Mackie HR624MKII's.
I believe it is your monitors, to a degree only. I have a little Fender Champ VibroXD and it sounds killer-it only has an 8" speaker in it.
You should be able to record exactly (pretty much) what you hear.

I love my little '70s Fender Champ. I put a Weber in it.

I was fairly pleased with my hardware Pod v2 until I got Guitar Rig.  I am phenomenally happy with GR.  I have GR4, but I understand  GR5 is even better.

I totally agree with this assessment. The monitors will add high end that you do not get from a guitar cabinet. This will also highlight any background noise and hiss that will occur. By plugging your boss straight in you are not getting the benefits of the cabinet. This is why some people suggest you mic a cab and others say try cabinet simulation. the great debate remains over which one is better.


In my case I believe placing a mic on a good amp and cabinet is the ideal situation, but I share my home with my family where my studio is, and volume is an issue. My little studio doubles as an office/computer room and I don't have the treatments I really need on the walls. This really limits me. So amp sims are what I am stuck with. Being a solo artist and only recording my music gives me a studio that fits my needs. but I must figure out a way to get great tone. The amp is fine for playing live or open jam sessions, but not everyday recording use.


I have a rack-mount Pod pro 3 and Pod farm 2.5 which is awesome. I also have the full version of TH2 which is much better then the version that comes with cakewalk. between these two products I get what I need, but it is not without a lot of trial and error.


If you can't mic your amp plugging straight in with the boss will not give a great tone. You will need to find a program to simulate a cabinet. without that you are not going to get a good guitar tone unless you use a mic.

Thanks to everyone who replied.  My guitar goes into my gt6, which in turn goes into my focusrite saffire 6 usb, which then goes into my mixer and plays through my monitors. The job of the monitor speakers is to give you a true unembelished sound and  they do, but no matter what settings I use on the boss, I cannot get a decent guitar sound through the speakers.  

I cannot get a good quality guitar sound through my speakers. I am looking for the same sound quality as I would get plugging my guitar into a guitar amp.

Sound quality is in the eye of the beholder. Maybe that guitar FX is not for you. But i can tell you that no one here can say set it up like this and you'll love the sound, as there is no magic settings for these things. Sell it, if you cant get what you want out of it. Ive bought some effects i did not like. That's life.
 
If you want your guitar to sound like when you plug into your amp, then buy an SM57 and a ribbon or condenser mic and mic your amp.

Well, those of you who have read my suggestions before know I'm a true non-conformist...so this may sound crazy to a lot of folks... but have you tried just recording a clean guitar part, then running that track through your guitar processor(s) to get the sound you are looking for?  I do this quite a bit, successfully.  A side benefit is you can try out all the processor sounds and not be "glued" to just one.
Guitar Rig 4/5 works really well this way, as does some of the many free amp sim plugs like Voxengo's Boogex.
And of course, you can use any combination of FX you desire on the clean guitar track.

Just trying to come up with another solution when all else has failed you...

Good luck!

I don't think you will ever get a good guitar tone with the Boss GT6 plugged straight into your interface. I have never had a good tone coming out from just an FX unit like that. The guitar sound should already have gone through a cabinet before they get to your studio monitors. The GT6 is great for playing with an amp tho, if you like the sounds.

If you really want to use your Boss then I suggest you add an amp sim or cab sim to the front of your effects chains and use the simulated cabinets in those to get a more natural tone. The Guitar Rig LE or Overtone TH2 will do this job just nicely. If you're up for more fine schmecker stuff, AudioEase have a pretty decent cabinet simulator. I think there are some freebies out there too but I haven't looked much into that.

For amp cab sims, I highly recommend cag IRs.  Redwirez has a ton of real good ones.  Same cabinet, different mics with different mic placements.

If you can't get a good cab sound out of one of these, it isn't the cab that is the problem.

On another note, the problem I have with DI'ed guitar recording through simulators, is the relationship between the signal attack and the sense of air.  DI'ed guitars always give me too much attack as part of the overall volume and by the nature of the method, there is little you can do about it.  

With a LIVE rig, and mic placement, the attack portion volume is naturally taken care of but the real signal chain.

Just my point of view and why I have moved more to LIVE tracking than using DI's and sims.

Good point about the lack of air Jim.

However, here's a trick; I usually insert a convolution reverb on my guitar bus with a room sample. It should be short and pretend to be the room where you would put an amp. I use a variety of studio or small room IR's from Altiverb and set it to 70-95% wet depending on the IR. it's not the same as a mic in front of a cabinet, but it's close enough sometimes and work surprisingly well for a lot of things.

I have also recorded my studio speakers with a mic and back into the project with varying results. But when it workes, it's quite cool
