For about 2 years now I've been a proud owner of this particular bass https://www.thomann.de/de/warwick_rockbass_streamer_4_sbh.htm I'm looking to change the pickups, but as you can see, the original MEC vintage passive pickups have this kinda round shape, and also the "holes" in the body have this round shape. To clarify, I do not have any kind of experience with replacing bass/guitar electronics. This is my very first own bass and I'd just like to upgrade it, since I love the way it plays. So my question now is: Can replacing these pickups with for example MEC's MC-4 (https://www.thomann.de/de/mec_mm_style_mc_4_brushed_chrome.htm) cause any problems solely because of their shape? If I was to build in a typical MM-style pickup, there would be a gap in the body, right? Or does anyone in general have any experience with changing pickups on a Warwick RB Streamer STD? Thank you in advance, I'll gladly answer any questions if my descriptions were a little confusing.
