I have a pair of blackface non reverb Deluxes and have been looking to replace the V30's I used for years. I've been thru many speakers recently both alnico and ceramic and have found the ceramic Silver Bell is the one I'm looking for. Great low end. I have found I can turn the bass up to 7 or even 8 and it doesn't flub out, at least in my case. My Silver Bell must be broken in as I have used it in a 1X12 cabs for a couple of years, many hours of playing. Big warm tone with plenty of detail for me. I liked it better than my ceramic Blue Dog. My Weber's are 50 watt, light dope, and I prefer a 16 ohm speaker in my Deluxes.
