I have an MTD Grendel 5-string which I have really enjoyed playing. It has very nice balance and I have fallen in love with the 35" scale assymetric neck. However, shortly after I bought it, I played an MTD Kingston and loved the growl that bass produced. I have since enjoyed the sound of MM bases. Just last week I listened to an excellent bass player on a cruise. His bass was tight punchy and had a mild growl in the midrange. I talked to him after the show and he showed me his Warwick Streamer Stage II (5). I loved the sound of this bass also, but I'm wondering if there is a way to get that sound from my Grendel. Some information: I play 100% fingerstyle and play some mellow and some more alternative rock music. I usually play with mostly the neck jazz PU and use very little of the bridge PU. Since I don't use the bridge PU very much I was considering replacing it with something that I could blend in some of that growly tone I'm looking for. I thought about a basslines jazz pickup, but also considered routing out the top and adding a large coil MM style bridge pickup. Any suggestions on how I can add growl to my Grendel?
