Cutout dimensions for a Tweed Bassman?

[LeftyStrat]

I'm ordering a Tweed Bassman built out of pine, but this one is going to be a little different and I think I might end up with two rows of controls. I know the chassis dimensions of an original are 20'' L x 4 1/8'' W x 2 5/8''.

I plan on increasing the depth and have two questions.

- What are the dimensions of the cutout on an original?

- If I increase the depth will I run into clearance issues with the transformers and speakers?

Probably. I don't know the dimensions of a standard Bassman cab, but I do know that the upper two speakers do not have magnet covers so that there is sufficient clearance for the transformers.

Thanks guys. I'm making the cab two inches deeper.

Good idea! I think they sound a little shallow myself. Ya know, I likes some bass.
