Hi. I´m new to this site, and new to amps. I´ve played for some years, but never really bothered that much about pedals and amps, until now. So I´m a noob. Bear with me... I´ve just got myself a JVM410H with a 1960a 4x12 cabinet(ordered online). I was super excited to get it home and try it(at bedroom-friendly levels), but I got some issues with the sound. On OD1 and OD2(orange and red - and a bit on crunch/red), the sound seems flat, and there is a fizz/buzz/magnetic-"kindoff"sound when I play(especially when I play the lighter strings), which gets stronger when I up the gain on the amp, so I now have to play with gain at 9-10 at most.. I don´t really get the warm/fuller tone I want, when playing rock/metal. I´ve read about mods and pedals all over the internet, but I´m totally new to this, and would like some advice. It´s the tone itself that is the problem, so any hizz/buzz/fizz between notes is not an issue. - Is there any chance that there is something wrong with my amp? - Will it be better with a pedal/noise gate? - Anything else..?
