Sorry if my post came-off as being anti-Line6, but I believe I speak the truth. While I love my Line6 gear (Spider IV 75w and SV100HD), they aren’t pro quality. I don’t have an issue with this because I knew it going in, but I can understand the frustrations of those who purchased the SV line of amps expecting them to perform better than they did when trying to use them live. The sound drop and/or “pops†when switching channels, the super-sensitivity to voltage changes, the overheating, etc., etc., are non-issues for the vast majority of bedroom players, but they make them unsuited to use in live settings. Again, I don’t have any issues with this because you can’t expect to have no compromises with an amp in this price range. If we were talking about a high-dollar Mesa, Marshall, Fender, etc., etc., these issues would be inexcusable (and most likely quickly rectified by the manufacturer).
The only real issue I have with Line6 in regard to the SV line of amps was their misleading ads and literature that suggested that they had tubes in the preamp.
