#Super pro speakers mod#
We usually start with explaining a mod from a functional perspective where we relate to components in the logical schematics diagram. You’ll need schematics to implement some of these mods. If you also implement the tremolo disconnect mod you can really make the amp break up at practise volumes. Tube mods (pulling V1 out and a 12ax7 PI) will take you a long way. Having an AB763-similar circuit, there are many mechanisms in the circuitry that you can tweak to suit your needs, basically to increase or decrease the clean headroom. Personally we like to mod the amp so we can make it smaller when needed. Like all silverface amps, the Pro Reverb was modified in the CBS periods to increase the clean headroom making it thinner and harder sounding. Speakers are very difficult to recommend since the tone experience is nothing but personal taste. A set of Celestions give you a Britsh Marshall color with strong mids, while traditional Jensen-style speakers give you the classic Fender tone. Different speakers may alter the tone significantly in the Pro Reverb, as in all amps. The 2×12″ speaker configuration can deliver lots of punch and powerful mids that cut through with a good sound spread on stage. In modern times where low wattage breakup has become desirable, the Pro Reverb has become very popular. In the blackface and silverface years players wanted powerful amps, and the Pro Reverb was probably considered too weak. For many years it has been a relatively unknown amp.
The amp is less powerful than both the Twin and Super Reverb and we’d place it somewehere between the Deluxe Reverb and Super Reverb. The power transformer and power tube circuitry is equal to the Super Reverb, but a smaller output transformer lowers the clean headroom and introduces sag and breakup. Together this makes the Pro Reverb break up significantly around the usual volume level 4, while the Twin Reverb is clean almost all the way up. It has half the number of power tubes, smaller transformers and a tube rectifier in stead of diodes. It has the same 2×12″ speaker configuration as the Twin Reverb but has a less powerful amp. The Pro Reverb is one of the beloved 40W 6L6 working horses.
