Summary: I was bought this amp a while ago, and I quite like it. The main difference with this amp is that you don't need a set of pedals to make sounds, as there are literally hundreds of preset sounds already loaded into the amp itself (Line 6 do offer a special pedal with 4 foot switches to change sounds if you are going to be using it live).
Summary: I got this amp a couple of years ago, to play on my Epiphone Les Paul Standard. The sound is perfect, the clean is clean, the twang sounds twangy, the blues is bluesy, and so on, every effect setting is perfect. I'll never need another amp, it's perfect for recording with a headphone/output jack with perfect output sound quality. the inbuilt tuner is very handy and picks up each string without difficulty, it's very easy to use and easy to understand.
Summary: This is the first modelling amp I have owned since I have been using a Marshall 8080 valvestate for the last 15yrs. I bought this amp (75w)for the convienence of having so many sounds all contained in one box. I was not drawn to it because of the Artist presets- too gimmicky for my liking. The range of amp sounds are great and far reaching. Likewise the built in effects allow endless possibilities when creating your own sounds.
Summary: To be fair I don't own this amp, I own a Spider II cab and head, I tried this out at a guitar store and there's very little improvement. I thought I'd offer a little insight into why I don't like this amp. Firstly, if you're not familiar with amps, there are three different types; Tube amplifiers, Solid State (or SS amps) and modelling amps (Line 6).
