Power Supply Question

I have been getting fustrated with going through 9v batteries, so I'm making a stand against using them if I can help it. I have a power supply that came with a pedal I bought a while ago (output 9.6V DC 200mA), but I have one more I found around the house (from non-guitar related stuff):

Class 2 Power Source
Input 120V AC 60Hz 6 W
Output 9V DC 100ma

Is this safe to use with guitar pedals?

Either will work, but they will likely need a lot of additional filtering if you don't want to hear a lot of hum in your playing. Search previous threads here for recommendations on how to set this up. Also note that the output voltage will vary with the load, and a 9 volt output does not give you enough headroom to add a regulator. I generally go with 12 volts into a regulator to get a solid 9 volts under load. Bottom line: What you want to do is possible, but you should know the limits and some ins-and-outs before you start.

For most power supply situations, I just use a One Spot. Haven't had any problems with them.

one spot with the octopus connections is the best item I have bought. Gives clean power and supports all of the pedals I use, except my valve caster, but that use 12v at

just be careful about polarity. most pedal adapters are center neg, but household ones could be the opposite

always think outside the box
