I dont think the heavy gauge strings will work on the harmony, I tried 12's then 11's but settled for 10's as they had the best balanced sound, but ever guitar is different. fenders do suit heavy strings as that is what they were designed for, especially the jaguar which will sound crap with anything less than 11's. My vox has 11's but would probably sound better with 12's but its a killer trying to get blues bends on 12's, hard work. To get those vintage tones try high gauge vintage re-issue type strings as mentioned above, that should do it, never use less than 10. I used a set of 9's on my hofner galaxie to calm it down a bit as the pickups are so hot it growled too much, but as i'm used to 11's & 12's I just broke em all (3 in one gig), playing and bending way to hard : )
