I'm in need of a 5 string, though if I get a 5 a 6 wouldn't hurt. My first thought was to grab an inexpensive Ibanez sr and change the electronics. Going that route will cost the price of the instrument plus $600 for pups and pre. So about $1000. I enjoy the btb's. They feel nice and play well. I've never had the opportunity to play a Mayones but man it looks amazing. I just dont know is it is worth double the price. I will say aesthetically I enjoy the Mayones more. It almost looks like they come from the same factory. How do the 2 compare in sound? They seem to be similar in quality. Here are the 2 in question. The 3rd option is an Ibanez 305 with a complete overhaul. Tuners, pickups, electronics and possibly bridge.
