Thank you all for your input and ideas. I probably should have clarified up front that I bought the fretless with objective that it would be a secondary instrument, not my primary bass. I want to use it to make be a better player on the fretted instrument, plus as an additional tool in my toolkit. I chose the SR370EF because it has a neck identical to my SR1350B, at least in terms of physical dimensions and general intonation. I alternate between 3 fretted basses, playing one per day, then moving on. I find this keeps me fresh and challenged. For now, I'm going to put the SR370EF into that rotation, so it will get played exclusively for one out of every 4 days. I'll see how that goes. Rich Brown has a drill outlined on his Brown'sTone YouTube channel that I will follow, which includes ideas some of you proposed, and I will use a C drone. I've used a lot of Rich's videos and they are always excellent and efficient. Fyi, I learned originally by ear, and my fingers know where to go on the fretboard (eh, maybe not so much in upper register), so it will be about adjusting intonation, and position. I may have to change finger technique on fretting hand for the upper register, since I'm more a pads player than fingertip player. I will record my playing and painfully listen to whatever crap I'm producing to try to improve technique and intonation. If all of these do not work, I will consider putting my fretted basses away for a period and focus exclusivley on the fretless, until I get it to at least a decent level. Again, though, I am always going to be a fretted player first, fretless second. By point of comparison, I leave my Ovation Elite Acoustic in its case, one of my oldest and most expensive instruments, even though I love it and tend to play it exclusively when I get into it, because if I play it for more than a matter of several days in a row exclusively, I come away ham-fisted. It wrecks my touch!
