After building pine cabs for my Vox VT50 and my Peavey Bandit Red-Stripe I have decided to do the same for my Cube 80xl.
I try to build the combo cabs exact or close to stock so I can use all corners and parts of the stock amps plus the stock amp covers will fit.
Now the stock cube 80xl uses 1/2 or 9/16 inch particle board plus tolex which makes the sides about 5/8 thick. For this project I will be using 3/4 pine. I will make the inside of the cab the same dimensions as stock so the amp will be about 1/4" larger than stock in height and width.
I have cut the top, bottom and sides glued and screwed , let dry remove the screws, drill out then glue wooden dowels in their place.
Pics show the completed Vox , Peavey and Roland progress so far!

While I am working on Roland cube 80xl. I am wondering if anyone has converted one to an open backed cab or done a speaker swap.
I plan on opening the back or installing a removable panel.
But I may upgrade the speaker if anyone has done so ,I am open for suggestions.

I converted a Fishman Mini with new poplar sides and an optional open back. I used a 6" diameter boat hatch, round plastic. I faced the inside of the hatch lid with foam to avoid any resonance issues.. I had to cut it because the amp is so small, but on a larger amp you could just use the hatch round as it comes. It comes with an outside ring and the hatch screws out or pops out normally.

Finally had some time to continue.
Framed out the face with some poplar which tends to take the stain a little lighter than pine.
Cut a plywood speaker baffle using 3/8 ply was planning on using 1/2" ply but I am not concerned with strength cause it's such a small area 14 3/4" x 15 1/4".
Still deciding on open or closed back and whether to change the stock speaker.

Looks quite nice! I know the previous gen Minis had tolex issues and I was contemplating something like this. I've got a newer one now and the tolex is in good shape, but the real wood looks better anyway. Nice job!

I really appreciate you posting your progress here. I'll probably make a speaker cab at some point (once I actually have tube amp head). I was thinking about possibilities of construction, and you pretty much confirmed what I was thinking. Hadn't thought about removing the screws for dowels, though. I like that idea. You do good work!

yeah, that brown vinyl almost fell off on it's own! I guess they improved it.

Roland Cube 80XL pine cab finally finished. Be so busy haven't time post as it was happening.
I couldn't use the roland's corner protectors cause the wood I used was only 9 1/4" wide the roland's are about 3/16" longer. So used aftermarket corners. Made it open backed and sounds good but need to use it on a gig to really judge but Lord knows when that will be.
Probably 5-7 lbs lighter.

Sweet......I have a Fishman that has the tolex coming off if you barely touch it. I might give that a try with mine.

Thanks, removing the screws and drilling out and glueing in wooden dowels is actually very strong and allows the rounding of edges without hitting screw heads. One of these days I'll get a dovetail jig though.

Still waiting for a gig to give this the ultimate test. It is looking like 5/26/21 is the earliest one so far.
I purchased a stereo breakout cable to connect the left and right outputs of a Zoom G5 to go into the Aux in on the Roland Cube 80XL.
The Aux in bypasses everything on the amp and goes directly to the power amp. However it also bypasses any volume control on the amp, so volume will have to be controlled by the G5. I have never used a processor in this way before but I got time to play with it before the next gig.
