Has anybody tried these Ibanez 5-strings? I'm partial to the SR 905 but I haven't thried these others: Ibanez SR 505 Ibanez SR 3005 Ibanez SRX 705 How much? Hot? Not? r PS and let's keep the price ratio in mind. I know the SR 3005 is the highest caliber bass here but I'm also sure its WAY expensive too. So pound for pound who is the best buy?
