Richard:
I agree with Stratrhythm, you should probably contact a
real person at Mesa for a true diagnosis of your issue.
Some additional advice to consider:
1. What is the ohm rating for your SWR speaker cabinets?
(You can test this with a multi-meter or ohm-meter on the
male end of your speaker cable). It can be 2 ohm, 4 ohm, 8
ohm...
2. How many outputs are on the rear panel of your Mesa? At
what ohmage are these outputs rated? 2 ohms? 4 ohms?
3. Your amp output ohm rating and your speaker ohm rating
should MATCH.
4. How many watts does your Mesa output to speakers?
5. How many watts is EACH INDIVIDUAL SPEAKER rated at?
Usually you can read this info off of the back of the
speaker, sometimes the info is on a plate on the back of
the cabinet.
(for example, I run 4 x 12" speakers in my cabinet: EACH
SPEAKER can handle 300 watts...I run approx 300 watts from
my GK amp into this cabinet)
If the speakers in a cabinet are rated at 100 watts each,
then you shouldn't put more than 100 watts into that
cabinet (even if the cabinet says "200" on it).
6. Do you use any effects on your signal path? This may
cause unwanted noise.
7. Are the speakers in good order? In other words is there
any chance that they may have been damaged before you
acquired the cabinet?
8. Any loose wires inside your cabinet? Loose solder
joints? Loose jack? Loose connectors or jacks anywhere
along your signal path? Loose jack on your bass?
Just some ideas...you might want to see if Mesa can direct
you to an owner's manual for your particular amp. I
believe these manuals are online at Mesa's website.
good luck, fellow surf bassist...
