Double Bass Am i crazy ? - Roland Jazz Chorus

Mainly, just don't run it full tilt. The back has to be actually sealed in order to avoid the excursion problem. But then, it's a toss up whether those particular drivers would sound good in a sealed cab.

If you get curious enough, measure the response curve using my program. That would help you get to the bottom of what might be making it sound good for your bass. If nothing else, it would help choose a bass amp and/or EQ settings for a similar sound.

I guess the only problem with that would be you wouldn't know that you were damaging the drivers until they started to crap out. And over time, you would be stressing them to the point of excessive wear towards failure. It always sounds great up to the point where it starts to sound ****ty. You know, open back cabs are really great for bass guitars in the recording realm, but the string bass just kicks those speakers to hard to trust in a live situation, in my humble opinion. If the open back cab design worked well for bass, wouldn't we see them readily offered in the marketplace? They are a heck of alot cheaper to build, that's for sure!

Just came home from a two-gig night with my Cube , i thought i take the risk and brought it to both gigs.
It was a trio gig , a loud drummer and the venue was horribel for music , an old church , the other one a restaurant.
Its a long time ago i took this amp to a gig , but it was realy awesome , i had PA support , used a linebox , i really could pump the volume up to 50 & without distorting and loosing quality. I will definitly use this amp moore on this type of gigs , actually i like it little better then the AI in this type of rooms.

Yes! Long ago I used a Cube 60 guitar amp (grey) that I had stuffed a EV 12" bass driver into. It had spring reverb, fixed Chorus, boost, and nasty distortion built in, foot switchable, all excellent ,and all very usable. Great EQ. With P.A. support it was all I needed for anything. Can't remember why I gave up on it, but I wish I had it back. Now I have the WW Ultra, it's great, but the Roland Cube took care of business quite well.

Certainly a reasonable point. Good bass drivers can handle some over-excursion without damage, but maybe I would not be so sure about an old open back guitar amp.

I accidently blew one of the speakers in my JC-120 using it with bass.

Has anyone out there any experience of the new Roland Bass Cube?

There's one BC 100 at the school I teach - I wouldn't recommend it to DB. It's not an acoustic instrument amp. It has some digital effects and amp modeling presets, for me these are unneccesary. Too much possibilities but weak sound.

The Roland JC (120, 77. 55, ect) series amps are great for bass....only problem for might be blowing speakers, since the it's an open back cab. If you must, you might get away with stuffing a blanket in the back or something. Then again, that might start a fire!

what if you replaced the speakers to bass speakers?

i loved the fender super twin reverb amp for bass, i have been looking for a more affordable similar or equivalent..

For a time I jammed in a room with a huge Fender (guitar) amp with 6x10 inch speakers. It sounded great, probably as a combination of valves and a large area of cardboard cones, but ofcourse totally impractical. Other amps that felt/sounded surprisingly great, were small Yamaha combos hanging at the wall at Berklee, and an oold, small Vox bass combo at a friend's studio. Both would probably be insufficient for gigging, tried it with the Vox once...

I used a JC-80 for years as a bass amp, it was pretty good. I then sold it to a keyboardist who played it for many more years.

I still have the JC-80 I bought around 1982. The whole JC series seem hard to come by but particularly the 80. I think you are the first person I have come across who had one.
