Found a used zebra custom back in october but never got around to putting it in the Hamer. Did so last night and tried it on my Laney vc100 and it sounds great! The stock 57 was just lacking that punch and bite that the custom has, and it is a great balance for the neck 57 still.
On the Hamer, it gets a great rock-to-heavy rock sound, good palm mutes and excellent sustain.
Count me in with the Custom likers crowd!
