I was thinking of putting some additional controls on the front panel of a JTM45 type build that I'd like to get going.
The chassis I've got is blank, no holes / cut outs.
Was the original Bluesbreaker built using the same 17" wide chassis as the regular JTM45?
I'd like to know the control spacing for the BB, and ideally a full chassis drawing.
So I'd be very grateful if anyone has any links to such info, or files they could share.
TIA

Two models. There is a /T model that is wider and has two extra controls to the left (after pres) spaced just like the others. only wider by two spaces.
I'll measure my panel openings. It's wide.

The original BB was in a bigger cab according to this article

I think one could scale the chassis dimensions pretty accurately from this

Yeah they are deeper and the profile and every feature is totally different.

Re: Marshall Bluesbreaker Chassis Drawing
Scaling the front panel width from the cab width seems to give 22", quite a bit more than my 17" chassis.
So I guess the control knob spacing will be 1.5"?

Re: Marshall Bluesbreaker Chassis Drawing
Marshall knobs are 3/4" diameter, so in the picture above it looks like they are on 1.75" centers. I agree the chassis is probably around 22" (without the flanges), so you'll have to scale the spacing down to fit your width, 17/22, that would be 1.35".
