I own a CORT A5 purchased new 7 months ago...and I'm not able to use it in any way! Don't misunderstand me, the bass is well made for the money, with a great playability and a pleasant acoustic tone. The real problem is the amplified tone. No matter how you set the amp or the onboard electronics, the bass retains the basic character producing a very bassy tone with an annoying peak at 40-100 hz that kills every other frequency. the mids are there, so the highs (quite metallic to my ears but this is active sound...), but the boomy big gun does not allow the notes to be intelligible. My amp is a great Markbass rig that sounds clear, balanced and brilliant with other basses. In my opinion the problem is the crappy korean electronics, a full Bartolini MK1 active system. I'm seriously thinking of eliminating the preamp and rewire the PUs in passive mode. It will be better to buy other PUs but I haven'y got enough money for now...need help and advice. The stock MK1 PUs will work without the preamp? How to connect them to the master volume and blend pot and the output jack? please, i'm in a babel...thank you in advance!
