Thanks.
The Mules are great .I had them in my old VOS 57 and PAF stickered T-Tops in my old 71 routed gold top at the same time.
I love both,but prefer the Mules.They are similar,but more articulate and focused.
I like the twang of the Flat 50's. I like the Brown Sugars extra gain,but might try and trade the them for Yardbirds which I originally had in the 62 RI.
