Features the pro junior iv features a 15 watt tube circuit driven by a pair of el 84 power tubes and two 12ax7 preamp tubes with a solid state rectifier.
Pro junior cabinet upgrade.
These features truly earn the pro junior iv its pro title.
We ve gotten some really great feedback on this upgrade for the pro jr.
In this case i feel like a 10 would sound spectacular in a blues junior cab whereas the 12 speaker never quite does it for me in a blues junior.
We ve always felt that the biggest limitation to the pro junior was the 1x10 particle board cabinet.
This larger cabinet actually weighs less than the smaller stock cab due to pine and birch construction so even if adding a heavier speaker.
Tonedog guitarworks is the home of the pro senior cabinet for your fender pro junior tube amp.
The overall tone is ok but they can sound boxy and small and for this reason many guitar players write off the pro junior as a non gig worthy amp.
From the factory the pro jr should have came with either an 8 speaker like a high powered champ or came in the blues junior box and the the blues junior should have either came with a 10.
The fender pro junior is a great sounding little amp and our 1x12 pro senior cabinet upgrade is a mod that will really open up the tone and make your pro jr.
I used to prefer the 65 princeton cleans to the pro junior but after this upgrade i have not played my princeton at all.
