... and what a difference it makes. It's a Marshall JCM 600 2x12 combo. It came stock with a half-back. Dad and I just fabricated the other half. It makes a world of difference. The amp is way tighter and more focused now. Sounds much much better. I encourage anyone with a half-back or open cab to try it, just to see the difference. The only concern I have is potential overheating problems. The 600 line has been known to get hot, and I just cut it's internal airflow dramatically. A fan may be in order if things get too toasty.

are you saying that you closed the back on an oopen back tube combo amp?

Yes

tube amps NEED that air flow...without it they WILL burn up, it will cause early tube failure, as well as other issues with other parts...it can also cause a fire in some cases...the amp might sound a lot better to you with a closed back but trust me when I tell you it is VERY BAD for the amp...if I were you I'd take the quot;backquot; off asap...

What if I left the tube/transformer area open?

Marshall stopped making them because they over heat and some of them cought on fire. As another guitar player and a nice guy Im telling you that it's a bad idea to do that...if you could remove some of the cab I'd suggest that! I'd take it off asap...and just before you ask an internal fan would do very little if any at all good.

ok thanks/sorry
