Ok...so a band mate and I have a disagreement going on. Shed some light on this for us if you would... Marshall 2203 and 2204 all tube...NO diode clipping. Marshall 2205 and 2210...Diode clipping. Silver Jubilee and Mini...diode clipping. JCM 800 Studio Classic 20h...DIODES OR NO? After responses I will let ya know which side I was on...100% sure I'm right here though. CHEERS!
