There are many good basses out there for nice slap tones. Some of my favorites are the Lakland 55-01's, 55-02's, and 55-94's, the Sadowsky M5-24, especially with the EMG 40J's, and my Valenti J5 has an incredibly hot slap tone, also with the EMG 40J's and an Aguilar OBP-3 preamp. I also love the sound of an active Fender Jazz or and active Fender PJ. MTD's have a very hot and bright tone to them which makes them great slappers as well. Well shoot, you might as well throw in my old Kubicki X-Factor, pre-Fender mind you. That thing was a beast. The Pedulla Thunderbass was a great slapper too. Much thump came from that bass.
