Short answer. No.

20W solid state digital is nowhere near powerful enough to play over a live band instrument mix, and definitely not over acoustic drums.

What the Spider V20 MXII is is a (relatively) low powered versatile practice amp. Adequate for home practice and the learning guitar task.

That said, I note the Spider V20 MXII has an acoustic voicing or mode, so at a guess it'd probably do that just OK for a very small coffee shop type venue or school class room/family room at home single acoustic guitar 'gig'.

P.S. Edit: Looking out of curiosity, I found this for you. Played on an entry level Cort CR-100 Les Paul clone and direct recorded into the (included Steinberg Cubase LE?) DAW, it gives you a fairly good idea of the amp's versatility.
