Fender Blues Jr. III vs. Blues Jr. IV

The BJIV has a couple of circuit tweaks, Reverb is a little more laid back - cooler bias and a tad more low end and comes stock with a Celestion A-Type. I have the BJIV but stll added the popular Billm mods its a fine amp, I had the BJIII and its fine as well just not as full sounding to my ears but if you installed a few mods it would sound about the same as the BJIV.
