You can make a lot of base and specialty malts from pale malt at home with a minimal investment. Specifically a large roasting pan exclusively for malt roasting and toasting.
I made a great brown ale from 100% pale malt. My grain bill was pale malt, amber malt and brown malt. I hot-smoked/roasted the brown malt with maple wood chunks. I oven roasted the amber malt. I also dried out the beer with some maple syrup right after the sparge.
