actually visualrocker69, that last bit IS important....
yes, Boogies are fixed bias amps. However, that doesn't that mean you never bias them.
To have any tube amp operate to it's best, they must be properly biased, regardless of whether they are "fixed" bias or "adjustable" bias. In the case of a "fixed" bias tube amp, it usually means that the amp must be biased by a tech that knows what they are doing. Many of us "old dogs" like to refer to the spark plug/car analogy...you can buy the spark plugs off the shelf and put them in as is and your car will operate ok. However, if you want the best gas mileage and performance, you have the spark plug gap(s) set the the right gauge. Essentially, biasing new tubes to your amp is like fine tuning the engine of your car.
Back to the Boogies....every new Boogie is biased "cold" from the factory. Every Boogie owner that has had their Boogie rebiased to proper settings (by my service) has been blown away by the difference in tone and response. I'm sure that the same would be true for you if you would have your Boogie rebiased too...as long as it's done properly.
