Hi guys.. I know that power supplies like the dc brick is expensive.. Is there any other alternative products that can power up my pedals.. Or.. is it advisable to save up and buy power supplies that are with the same league as the dc brick.. My pedals are a ibanez tubeking 12v, a ge-7, artec delay, and fender tuner. I'm gonna expand my rig further... So, enlighten me guys.. Thanx.. I'm so new to this..
