I have had a femder princeton 112 plus for about 12 years now.. In recent discussion with a friend who is a professional musician, i questioned which to replace, the above amp or my zoom g2 multieffects pedal. I brought it down to jam and played the pedal through hos mega boogie roadster and the pedal sounded very solid.

So, i went home and began searching for an affordable tube amp that wouldnt cost me more than 600/800 or cheaper.. Amidst my search, the same friend called and said he was thinking about my next step, and felt buying the line 6 pod hd 500 would probably solve all my problems while providing a device to record through and many other benefits. I repeated many times- " but my amp sounds horrific, wouldnt the line 6 sound somewhat worse as well? He insisted it would not, and the processor would cure all.

What are your thoughts? My friend has been touring the world for a couple years now and has my absolute respect when it comes to anything guitar/music, but figured id seek a second opinion(hopefully a ninth or tenth opinion as well)... Here is a link to the line 6 processor as well, although i hope posting it does not lead to ill conceived advisement haha.
