Running two amps !!!!!!!!!!!!!!

[BD13UK]

I want to run two Fender Blues Juniors together without using an untrustworthy Y cable, can I just make up a unit with one input jack and two output jacks  in say a Hammond 1590 enclosure or do you Guys have better suggestion.

i run two amps using a simple A/B box like the one you're suggesting. it's totally fine. I dont know about ground loops, but it's never been a problem for me.

the sound of two small amps spaced apart a bit is awesome. much more interestin to me than a single 4x12.

If the Blues Junior has two input jacks, you can just run a cable from the other input jack to a second amp. This is no different than how people have been "bridging" the two channels of their 4-input Bassmans and Marshalls for decades.  The Bassman has two input jacks for each channel.  A short patch cable gets run from the unused jack of the channel you plugged your guitar into to the input jack of the other channel.  Not as perfect as an active splitter, but it works.

you can check in the archive's here or go over to Geo, both place's have good info on A/B box's, you can do a search here also, just check out the header bar up above.

I think RG has a nice A/B/Y box design for this sort of thing at his GEO site.

It's possible that you might like it better if you drive it with a buffer/preamp. I use a mosfet booster, set for unity gain with four output jacks to drive several amps.

.....I like to run my pedals into a stereo delay/chorus unit and out into two amps......when  effects are off,it sounds great,an when the stereo effects are on,it sounds thicker(as long as you aren't adding too much of the effect)....

Just to say Mark that the Junior only has one input hence the reason I need to use another option unlike using an old Marshall head Bassman or AC30 etc, thanks for all the help and suggestions Guys as always it's most appreciated.

If you plug in with a regular "Y" cable type of splitter, the input impedance will be cut in half so keep in mind that it will affect your tone to some degree. Almost any buffer will solve that problem.

The other issue is that of ground loops. Make sure both amps have three prong plugs on them(!). Your absolute best bet I think is to use a transformer isolated splitter, but with both amps plugged into the same outlet you can probably get away with almost zero hum.

Take care,

Off topic, but tonight at the blues jam, I had to use the hosting bands guitar players amp. My crate vintage thirty needs some power tubes (lost volume bigtime and got muddy last week, they're old), so anyway, I must say... For a rated 15 watter, that little blues junior has some seriously big balls... Holy crap. On only 5 on the master, my strat pushed it real hard, great bluesy sound and OMG, the treble pickup was just plain frightening... I'm gonna get one of those little guys, for a amp of less than thirty pounds it'll do all the blues clubs I gig at for the most part, makes me forget all about something bigger until the venue is larger, then I'll have the 30 watt crate, but just wanted to say how impressed I was with the B.J., massive sound, light weight and not super expensive. Fender done it right on that one, PC board or no..
