my favorites are the Fender 69’s but I also really like Fat 50’s, Antiquities, Texas Specials, 57/62, and Lace Sensor golds. Last but not least the stock pu’s in your Strat are pretty good. Have you experimented with adjusting the height? For your Blues. Jr, have you tried this: turn both master and volume to zero, then turn the master all the way on and turn the volume in small increments. This will give you another tone from the amp. You might like it, might not but it’s easy and free.
