I currently have a Schecter Omen 6 FR and a Squier SP-10 amp. I am looking to upgrade my amp but I don't have much money. I will have around $100 if my stepbrother buys my squier and squier amp and I have about 30 bucks saved up. I also have a VOX wah pedal that I could maybe sell for $100 if my friend wants to buy it.

So far I am looking at either a Roland cube 15x ($240), Line 6 Spider 3 15w ($200) or a Marshall MG15DFX. Is it worth upgrading from my pile of shit to a small 15 watt amp or should I wait about 3-5 months to save up more money for a better amp.

NOTE: I don't have a job.
My Gear:
Epiphone Les Paul Standard
Peavey Vypyr 30
DW Collector's 3 pc drums
Mapex Black panther snare
Sabian AAX/Zildjian K cymbals.
save the money, the only decent amp in that list is the cube. save up for something that will last you for a while till you cand pay for an amp that is in your price rance and will suit your needs. ex. gigs, recording, just jamming
