Power supply for just two pedals?

[the low one]

I'm in a similar position to you, I just use the MXR M80 and MXR M288 most of the time. Occasional use of a chorus but more often than not just the two.
As I DI most of the time as well as connect to the amp I use phantom power for the M80 and therefore I won't buy a PSU for just the octave so I use a battery.
Your Tone Hammer will also run from phantom power so that could be a simple option for you.

You problem is that the Tone hammer is 18 volts, Your hitting it with 9, half. Way under current means no headroom and noise. You'll have to use 2 power supplies a 9 and an 18volt.

My soap box on 18 volt pedals. There is a chip that cost about a 1 cent that can take 9volts and step it up to 18 volts. It's common and in a lot pedals and other electronics.

The Visual Sound Visual Volume actually runs 18volts on a signal 9volts battery, because of this chip.

There's only one reason for not using the chip in a circuit. They want to sell you a $30 power supply that cost them $3 to make.

You could also use a 1Spot or Godlyke Power All power supply with a Voltage Pump like the Godlyke: http://www.pedalspluseffectswarehous...god-pwrpmp.htm It is basically just the chip mentioned in the above post added in to a basic adaptor that attaches to your power daisy chain. The only downside of a power pump is that it eats up your power supply's maximum amperage, but the 1 Spot has plenty at 1600 mA, so it has plenty to spare...

I suspect in some cases it's more that they're trying to keep the manufacturing cost down. I have a couple of 18v pedals that both came with a PSU included.

Like I said above, that chip costs about one red cent. A whole American penny. There is only one reason to make a pedal require a 18volts at the Jack. $$$$. If this were NOT true why would the NOT go with a considerably cheaper option for them and more convient option for the user.

The chips not even rare. Its very common and in thousands of electronics. Every engineer knows its available.

Some higher end pedals have started allowing universal inputs. For example the basswitch IQ. It takes 9-20 volts AC or DC.
