I agree with Denny, but I think the IBUs can be even lower and any pale base malt will do. Personally, I would use 2-row or a British style base malt, shoot for 1.040-1.055 and 20-30 ibus with no dry hops and no major whirlpool addition.
That said, I have run numerous yeast strain semi-experiments with standard American Amber Ale and Special Bitter recipes and have been pleased with the results.
