Ooops, I was wrong...I rechecked the speaker serial numbers and the original Fender Musical Instruments 12s in my Silverface are made by Pyle. I think EV's or JBL's were a $50-$100 Fender factory option on an amp that originally MSRP'ed at $1,000 back in '81 when I bought the thing.
I spoke to Bill Boekhoff today. He quoted me $500 delivered to my door for a gorgeous oversized (i.e., larger than stock) hand-rubbed and polished tung-oiled mahogany Twin Reverb cabinet with a center section in flame maple (same sound principle as a Les Paul) and mellotone grille cloth. He's making it with a covertible back that can be removed in sections to tune the bass response and openess (made from 3/4' mahogany). He's also going to supply me with new Weber California 12s at a discount which are modern versions of the old discontinued JBL D120F.
Bill is a Fender tube amp freak: he claims to have at least 40 various Fenders of various vintages in various states of repair. His forte is rescuing old, banged-up amps...one's that only the amp chassis is salvageable...and turning them into gold by mounting them in one of his awesome hardwood cabs with new premium drivers in them for his personal use. He is a Silverface man (he actually prefers them over Blackfaces for certain types/styles of music) and knew exactly what I was talking about as far as my complaints went. I told him I wanted a clean amp, mostly for jazz and clean rock tones that preserves the headroom, but firms up and extends the flabby bass while taming the shrillness. He said that the mahogany/maple combo would sound nice, and the extended higher- quality convertible back would tune the bass nicely while calming the highs. The JBL-clone speakers are uncolored and would not break-up even at high levels. Sounds perfect! He said that If I didn't like the way the Silverface chassis looked with the new cab, I could get a new blackface panel from Fender for $35 and drill-out an additional hole for the Master Vol. without encroaching on the Fender Logo.
So let's recap: for another $500 plus $170 = $670 delivered I can transform my old Silverface Twin (a decent stock amp in it's own right, just ask Steve Howe, Ted Nugent, Tim May, Dennis Budomir, Tommy Tedesco, etc., LOL!) into a really toneful LOUD and CLEAN jazz amp! Hmmmm...lessee....TOTAL investment: Amp $250, Switch $5, Tune-up $80, Larry LeCover Custom 2000Denier Ballistic nylon cover $35, Sultone Cab $500, Weber VST speakers $170...
Grand Total = $1040 ($1075 if I want it to look like a blackface)
Spread that over 23yrs of ownership, thats $45/yr, or so, LOL!
Can I get an amp that sounds that clean and loud in a gorgeous hardwood cab with premium speakers for that kind of money? Remember,$370 of that money is already spent and the amp is usable in it's current state. If I change out the cab, I can always restore it to stock for an EBAY sale if I had to, or conversely I can put a chassis from a wrecked amp in it.
Decisions, decisions, decisions, LOL! Bill can have it delivered to my door in about a month if I place the order this week.
