I have 3 Ibanez fretless basses (370F, 370EF, 500F) and Love them all. Short and sweet, I would try the 500F and go from there. I say this because you are going to notice a difference between the size of necks. Your MM's is beefier than the Ibby's. Also, some don't like the string spacing on the Ibby's but I have smaller hands so they work well for me...Thank you, so SR500F is 475 USD and SRF700 is 790 USD, the range is 315 USD, is the price between them worth to have a SR700 or there is not much diffirencies between them and should I go for SR500F, what do you think ? If you know and experience with SR500F or Cort B4FL, can you share it please![]()
