I have the Flextone HD and I have a Duoverb...

The Duo is very light compared to the flex..

I had the duo for about 6 months maybe 8 months , time flys around here..

I just got the original flextone last week and I have not plugged the duo back in sense..

not because it dont sound great, it does sound great, the flex is a new toy and im positive ill be back to

the Duo..

The Flex has that cool presence boost, eq boost, distortion pedal type of boost..

the other thing about the flex that makes more sense is, it is not ohms picky, just dont go lower than 4  and your fine.

The Duoverb, is not like that, I have 2 of them, one works and one is a corpse... I accidentaly ran

the wrong ohm load on it and it popped... I loved the amp so much I went and found another one.. if that helps you at all..

I will have to admit to being somewhat of a tube snob until all this.. Im getting wonderfull tone out of this flextone HD

just a old flextone I think from 1998 or 99 .. this thing is LOUD , so is the duoverb... very very loud. If u knock all the bells and whistles

off the flextone and made it like 10 tube amps in a box with little options.. thats the duoverb.. its picky like a tube amp.. very clear, its a cleans and classic rock amp from hell, there is no Nu-metal sounds in it al all.. its a led zepplin jimmy hendrix "to a T" typle of amp... stuff like Pink Floyd, blues jazz.. it nails that stuff...

I also have a Fender Black Face Bassman and I just retubed it and all that jazz.. it sounds awesome... its a beautiful amp.. the duo almost sounds better than the black face, you just have to take your time,  these line6 amps offer more over the edge sounds than your average guitar player like myself is used to, thats where I read a lot of complaints about these amps "the fx sound bad" no, not really, not if you dont over do them, they sound real good infact..  if you dial everything into 12 Oclock and spin through the amp models, they arent all that different which is very true in the real world.

It does blow me away that I have "boutique" distortion going into seriously old school tubed tone and cannot get as sweet as a sound out of that rig as I can this flextone.. it took me 3 days but its there... and sounds great. As cheap as you can find duoverbs for .. Id highly recomend one. you wont be sorry... get the head version, I got 1 head and one 2x12 combo I gutted to make my head whole again, but i tried it as a combo amp and it isnt as cool, the head with cabs is definately where its at for me.  I have a lot more control over the over tone and volume.
