What is your opinion of this product?
I've been using Line 6 amps now since 1996...I have had several models, Flextone, 2 Spider III 2x 10" , a Spider IV 15, A Spider Valve Tube 100, an HD 150 Spider III, a Spider IV 2x10" . and now I just ordered a Spider IV 150 Stereo Combo 2x12" Celestion. Stereo makes all the difference on stage and off, and blows all the other amps off the stage...I did several comparisons with MONO Fender amps, Peavey, VOX, and others and the Stereo makes the sound HUGE... The MONO amps sound sterol and no color or movement to their effects...I just added the Spider IV 2x12" Celestions to get that BIG STRAT Bottom End for my favorite SRV tunes... These amps are rugged reliable and sound fantastic...I've never had one fail in 20 years now!!!
