hi guys...i have had my LA series SWR 15" combo for about 9 months now. I recently bought a Boss Overdrive pedal and ran it through it. I played it a few times and how i noticed when i play cleanly on my lower 4 and 5th strings the amp seems to sound slightly distorted. I dunno was this beacuse the amp can't take the Overdrive pedal? or maybe my battery is dying in my bass cuz it's active. what do you think. could i really damage my amp running an OD through it?
