its best if you get the tonecore adaptor. It is recomended.
anyway, if all your 7-8 pedals is drawing current less than the rated spec of one spot, it shud work. But if you are kind and dont want to overwork your one spot, you can separate using 2 one spot to power those effect
i use verbzilla with one spot in daisy chain with other effect coz iam lazy to add in another adaptor at times, it work, no hum. But if spoilt, i am willing to accept, coz i didnt follow the advice on using tone core adaptor..
so, if you wanna use one spot, try at you own risk. If you wana play safe, use tonecore adaptor..
