The Crawler has a great mid growl. It's quite thick in my swampashstrat. I guess it will even be more massive in mahogany. An Abraxas would be a good alternative for mahogany. Has a bit more topend chime then the Crawler. For the middle I would pick a Mule. So balanced, so much depth, full yet crispy. Abraxas and Mule should go well together, being both AIV's.
