My Marshall MA100C 100 Watt All Valve 2 X 12 Combo Amp

might sound different too up off the floor

I did notice before that there wasn't a whole lot of Bass in the sound of the Marshall, maybe there might be more Bass now cause the floor isn't absorbing it, might give it a test run later to confirm my theory.


Just did the test-run and yep, to my ears the Bass does seem a bit more thumpier and focused now that those Castors are on and the amp is a bit higher off the floor.


I noticed that the amp goes into musical-feedback easier at lower volumes now too.

Be careful when playing aggressively at volume as once on castors they can tend to wander around a bit, at least that is what I found out on my 4 x 12 slant front cab. Ended up giving the castors to our drummer for his 'Coffin Case' to hold all his cymbal stands, etc. and put a couple of strips of pine the size used in housing timber frames underneath running from front to back. Worked great as you could just slide the thing around a stage or in the back of the truck without the fear of it always wanting to move all over the place on it's own as if possessed by an evil spirit.

Our guitarist at the time had a Fender Twin with those side strips of metal that allowed you to tilt the amp back and use them as supporting legs. Great idea as it helped to project some of the stage sound to head height so he could hear his own amp.

Being off the ground a little bit now will help you hear things a bit better rather than have more bottom end as anything with an open back tends to lose a bit of low end grunt out the back too.

That's a good point, I actually thought about that prior to buying the new casters, and I made sure I bought a set of four that had an integral braking system so that the amp will not move once the brakes are engaged, each of the new casters has a small lever that is pushed down to engage the brake-system, works really well.

Mine didn't have brakes and if ever there was a slight tilt on the stage surface there was more rolling than rocking going on if you get my drift.

Another reason why I got rid of the wheels is that I had a sturdy chunky roadcase for the 100w Marshall Head which was about 8" to 10" high from memory and plonked the cab up on top of that to get a bit more of the sound nearer to head height.
