Okay, I have been playing guitar for about 4 years now and 3 of them I have had my Crate GX65. Now there is nothing wrong with this amp, I just feel like it is the time to get a new amp that has the sound I am wishing for and some more power.I would like to spend around $800 on this new amp.I am looking for an amp that has very crisp clean clean channel, and a very "high gain" i think is what I am looking for(the distortion I would be looking for would be like Blink 182,Red Jumpsuit Aparatus,Atreyu,Avenged Sevenfold, Underoath & Taking Back Sunday).I dont care much for the warm sounding distortion too much, although having that versatility to get that high gain and the warm distortion would be nice.I don't know what to get.Solid state or tube?

I have looked at the Vox AD100VTH thats about it.

Any help is aprriciated.

here you go man http://www.musiciansfriend.com/product/B52-AT212-100Watt-2-x-12-Combo-Tube-Amp?sku=481309 try that one out ive been researchign it heavily myself as i plan to try the head out which is 700 on its own if u want to spend a lil more for a cab too but anyway its 100 watt tube more than anyone will ever need very high gain has a bright button for the crisp cleans u were talking bout and from what i read it has extreme flexibilty hope this helps
i'm sorry, but i have to discourage you from getting a B-52. i came really close to getting one, but when i demoed it, i found the gain to be really piercing (in a bad way) and trebly. the tone just stuck to the back of your ears in a really unpleasant way. but definitely go all-tube. you won't be happy with solid state after trying it. here're some of my suggestions for an all tube amp like you described within the price you mentioned:

- Fender Prosonic or Supersonic (the reissue of the Prosonic).
there might not be enough gain for you on it, but definitely look into it just in case.

- Madison Divinity
looks like it was made for that kind of abrasive, crunchy, high gain sound in the vein of the bands you've mentioned.

- Carvin MTS3200
probably the best cleans i've heard at this price and the gain is pretty spectacular.

- Peavey 5150 combo and Roland JC-120 Jazz Chorus
for the price you mentioned, you have the option of getting both and A/B'ing them. the 5150 is the amp that avenged sevenfold, atreyu, and a host of other bands of their ilk used to play, and the JC-120 is widely regarded as the prettiest clean sound of any solid state amplifier. you've have to use ebay to find the right price for them, but it's definitely do-able.

- you can do what i do, and use a single channel, all-tube amp that only has a clean channel (i use an Ampeg VT-40, but other options are Fender Bassman, Ampeg V-4, or the aforementioned JC-120) and just find gain pedals that suit your tastes. for the sounds you mentioned, i'd suggest the G2D Morpheus pedal, Tech 21 SansAmp GT2, Radial ToneBone Hot British, or maybe even Boss' brand new ML-2 MetalCore pedal.

...anyway, hope that helps a little.
