hi,

I have just bought a head and cab but not sure which ohms to choose.

The head is a bugera 6262 infinium and the cab is a Marshall 1960a jcm 2000

both of these have 4,8,16 ohms

which ohms do i chose

thanks

any you like, just make sure the impedance you use is the same on both.

You CAN mismatch impedance one way, and still be safe. The amp should always have the lower number in a mismatch scenario, so 4 ohms going into 8 ohms at the cab is OK. The other way around will fry your amp. Best bet is to always match impedance when possible.

He's obviously pretty young, and I'd guess he's being raised by wolves, or at least humans with the intellectual capacity and compassion of wolves.


You finally made it home, draped in the flag that you fell for.
And so it goes

Really doesn't matter on a tube amp. With a SS power amp you'll get a bit more wattage at 4 ohms, but with tube powah it really doesn't matter.

I'm not sure about it. My amp (Mesa/Boogie) instruction booklet says they recommend using 8ohm so I get the best tone possible. That's what they say.

cheers guys. oh and btw, to turn it on do i flick the standby switch, leave it for 30 seconds or so then flick the power switch on and leave the standby switch on

Other way around. With both switches "down" ('on' and 'off' are sometimes confusing; standby off means the amp is on) turn the power switch up, wait 30 seconds, turn standby switch to up.

ok man, so they both need to be on while playing. Power switch on first, 30 seconds later standby switch on
#11
Yes. You'll figure it out right away, it only makes lights and noise on one setting.

The op asked "ok man cheers, what is the best ohm to use? best sounding, not sure of the diffrence" in answer to...

"You CAN mismatch impedance one way, and still be safe. The amp should always have the lower number in a mismatch scenario, so 4 ohms going into 8 ohms at the cab is OK. The other way around will fry your amp. Best bet is to always match impedance when possible."

He has the option of 4,8,16 ohms. If he has to mismatch, keep them close
