I bought my Spider V back in April and had nothing but trouble with it since. I have kept it up to date with the latest updates which cured my first problem with cabinet modelling switch. But now i am having more problems. -The built in effects for the reverb channel which intermittently cuts out on certain effects. -The sound, in that sometimes there is no sound coming out from the amp at all, both with the built in speakers (except drums/metronome), my cab, and my other guitarists cab. We spent 20-30 minutes last band practice trying to figure out what was causing the problem only for it to start randomly start working again how it was previously set up. This has happened twice now. -And the lack of power! It's 240watts, it should be enough to crumble the surrounding walls and cause all my band members hearing issues, yet my other guitarists 50watt Randall turned quarter way up sounds louder then the Spider V all the way up. Is anyone else having these problems and feel like they made a big mistake going for the Spider V?
