hey, i have just got myself a dsl401 and was looking at putting a Celestion G12 Vinatge 30 16ohm inside.

Any thoughts on this, is it worth doing, for and against..?

Im relatively new to the whole 'tone' thing, having come into some money and investing some in my equipment, so I'm asking the opinions of those in the know!

I play
Gibson Les Paul Studio
Keeley Rat2
Boss MD-2
Vox v-847
Boss OC-3

through the DSL401
Yeah do it, from what I've heard the speaker is the weakest part of those amps. Drop in a Vintage 30 and I think you'll be pleasantly surprised.
