    Anyone know any mods to get this amp more towards a Blackface Princeton? More headroom, sweet cleans with volume, great with drive pedals, etc.

    I'm interested in getting one and using it as a clean platform for pedals to use at blues jams and low volume gigs.

    Everything I have found on the net so far points towards getting more gain out of it and making it more "tweedy".

    You'll get the most mileage by replacing the speaker.

    An upgrade in tubes couldn't hurt.

    Here's now...put the Blues Jr. on EBAY and take the funds and buy a black face Fender...

    Sorry, I'm on my 2nd Blues Jr. and you aren't ever going to get a Blackface sound out of this boxy EL84 amp... You can push it into tweedland with the appropriate tube choices and some neat speaker selections...and maybe find a little Vox sparkle in the BJ, but scooped mids with BF tones...nope.

    I don't buy into those Billm mods...I'm read to much of his idea of tone and heard his clips...they all have too much bass and sound lifeless, imho.

    I've been through 6 different speakers in my current BJ (settled on a very good Emi Tonespotter, it's the best I've had) and tried some cool preamp tube choices (mostly V1 will give it a different tonal direction)...the amp is a basic, cheap, blues amps...nothing more , nothing less...a Carmen Ghia, Deluxe Reverb, Marshall 18watter, AC15 it ain't.

    Actually the Blues Jr. isn't bad at all IF you install bias control, bias it correctly and change tubes-

    El84"s: MATCHED JJ's biase to around 8.4W IPD
    V1: NOS 12AY7
    V2": Whatever you want/have....
    V3: 12AT7, anything but EH/Sovtek/any rebranded Sovtek.

    This is from experience...

    i was in the same boat, except with my pro jr. the amp was fun, then i got bored with it. too boxy and plain for me. i couldnt find any good mods for it, so i just sent it off to steve @ www.s2amps.com to have him do his 1794x conversion. cant wait to get it back. P2P baby!

    +1, BF it ain't...really no way to make an 84 sound like a 6L or a 6V. Victoria got as close as you can w/ the Victoriette/lux model, but the best option is to unload or leave it in the corner as a practice amp and buy the blackface sound.
