I know this has been talked to death though I have this query... My Alchemist runs two 16ohm v30's in parallel for 8 ohm and when I'm plugged into the 8 ohm tap, it doesn't sound as full or tight as when it's plugged into the 4 ohm tap. Will I damage the amp running a 4 ohm tap with an 8 ohm load? Is it just a matter of time or would it be fine? I ask as I'd had a mesa 20/20 power amp previously and there was no prob about running the 8 ohm tap with a 16 ohm load. Even the Bogner says on the back that I can use the 8 ohm tap with a 16 ohm load (and that it might just be quieter). So using the same concept 4 ohm tap and 8 ohm load, will I be ok? The tonal difference is TBH quite noticable which I wasn't expecting. Other amps I've tried this with have had no tonal differences. Any advice would be greatly appreciated!
