Amp cconversion?????

Hi Folks,
I've a 100w Marshall Guitar Combo.......just wondered if I replaced the Speaker to a Bass Speaker if it could be then used as a Bass Combo? Just played on the clean channel.....would it be possible any thoughts.....money's real tight lol.

Probably no good using the cabinet, the amp might be useful if you can hook it up to a proper bass cabinet. Assuming its a transistor amp, not a valve amp it should be OK(ish) for practice.
Sticking a bass speaker in a guitar cabinet is not a good idea for a number of reasons, but without wishing to open up a can of worms, it's safest to say your best bet would be to sell/swap the combo for a bass combo.

Unless you are already in possession of a suitable (12"..?) bass speaker, a s/h bass combo (or, as suggested above, bass cab...) would be a better bet, I'd say. An open-back guitar combo is not an optimum basis for a bass cab. Nothing to stop you using the combo 'as-is', of course, for low-level practice, but it would be quite difficult to convert it for 'live' use, and probably not cost-effective. Either sell it on (or trade...) or acquire a bass cab.

Thanks for that......not a major issue at the moment, cheers.

Bit green on all this......having troubles with our present Bassist and I was going to drop onto Bass was looking for cheap option.....as the Guitar Combo is very tatty and probably not worth selling or trading.

Stop gap measure at very low volume as the combo is biased to gtr.
Practice -at home- amp at best, but not with any sort of band context, IMO

I use a Hiwatt guitar head for bass (with bass cabs) they are ok but the tone controls tend to be biased towards guitar frequencies so you may find, like me. that you have to turn the bass and mids up full to get a decent sound
