In addition to that we’ll present some other tricks how to make it smaller, bigger, cleaner, darker, brighter, firmer or looser.
We would like to talk about one very cool BF Vibrolux we came over in 2010.
It was loaded with one Weber 10A150 and one Jensen C10q delivering together a decent, loud clean sound and with firm lows.
There was plenty of clean headroom with the stock “AB763” tube configuration (12AT7 phase inverter and GZ34 rectifier) for funky chords and stingin’ clean notes at volume between 3 and 4.If we wanted to get more breakup from the amp for some raw blues tones and keep he same volume, we did the following: Playing the amp around volume 5 and 6 gives a raw, unfiltered texas blues tone out of the single 10″ Weber 10A150.A blackface Vibrolux with a pair of gold and red labeled Jensen is just a fantastic amp.The Jensen serial number starts with 220 followed by production year X(X) and week nr YY.We have had a silverface Vibrolux in our gear basement with a set of blue labeled “Fender” CTS speakers (serial number 137-XXYY).
This amp performed extremly well too, with lots of punch and sparkle.The 2×10″ speaker configuration with open back cabinet is convenient, efficient and powerful “enough” for us.Sonically, it offers everything we look for in a Fender amp; A dynamic and sensitive touch, brightness, volume, ambience, spread and a decent weight.This particular Jensen speaker with a Neo Dymium magnet will hold up against almost any 12″ speaker and is very efficient, responsive, punchy and and can take a lot of beating without farting out or breaking up.Where the Jensen NEO-100 can be a bit dull and muddy, the Jet series Tornado excels with quacky and bell-like sparkling blackface tones.See page How to select speakers for general speaker recommendations.
