sounds like you have most of what you need . why not just spend most of your money on accessories? decent chrom tuner, strap locks, strings , treat your strat to a pro set up , a new guitar case? shed load of picKs!
every gig i play is a payer!!! if i can not recoupe my expenses (fuel,etc) i wont bother!!!! sad i know but to drive 20 - 30 miles to a venue only for poor advertising , overpricing on the door and poor turnout etc shouldnt come outa my pocket!!! on the other hand an awesome gig and money makes a top night!!!!!
if you have your wah before your DS1 then your putting a clean 'wah' before the effect. And same applies the other way round , as in , if you use your wah after the DS1 then you are 'wahing' a dirty sound, if that makes sense!!! personally I use mine first in the chain and finish with a boss grahic eq.
