Hello all, brand new to the forum but far from new to the world of guitars and Gibsons. I just acquired a 1991 Gibson SG Junior which is a guitar I've been trying to hunt down for some time. Now, I realize the tone purists will scoff at this iteration of the Junior since it has a full factory Tune-o-matic and ABR-1 stoptail as well as Grover mini rotos. I know some tone loss is inevitable but I can compensate with aftermarket bridge upgrades to a degree. The big issue with the guitar is the factory P-100 which I know needs to go and die somewhere quietly. What I'd like to know is what P-90 should I hunt down and even which pots do I (should I?) use. I'm more than familiar with OX4's (have them in a Les Paul), I've seen good things about the Wolfetone Meaner, Throbak etc. My goal is to get that famous warm, midrange growl from this nearly 30 year old plank. A lot of the video demos seem to portray the boutique P90s as clearer and more bell like almost like a Fender single. I'm fine with tracking down a new Gibson P90 as the easy solution. Would buying a true vintage 50's or 60's P90 make THAT much of a difference? Would Central Labs pots make THAT much of a difference? And again....I realize I'm suggesting blasphemy putting vintage parts into an inaccurate SG Junior reissue and no...I'm not interested in selling the '91 and just buying a true vintage 60's Junior for $2k-$3k. Just looking for the best off all worlds and I know Duncans (including Antiquities) are NOT the answer as many posters have commented online that Duncans didn't upgrade the stock Gibby P90s. Thanks in advance !
